I. Introduction

Chapter 1. Introduction
1.1. Introduction
This is version 1.3 of the Linux Standard Base Specification for the Itanium™ Architecture. An implementation of this version of the specification may not claim to be an implementation of the Linux Standard Base unless it has successfully completed the compliance process as defined by the Free Standards Group.
1.2. Purpose
The Linux Standard Base (LSB) defines a system interface for compiled applications and a minimal environment for support of installation scripts. Its purpose is to enable a uniform industry standard environment for high-volume applications conforming to the LSB.
The LSB defines a binary interface for application programs that are compiled and packaged for LSB-conforming implementations on many different hardware architectures. Since a binary specification must include information specific to the computer processor architecture for which it is intended, it is not possible for a single document to specify the interface for all possible LSB-conforming implementations. Therefore, the LSB is a family of specifications, rather than a single one.
The LSB is composed of two basic parts: A common part of the specification describes those parts of the interface that remain constant across all hardware implementations of the LSB, and an architecture-specific part of the specification describes the parts of the specification that are specific to a particular processor architecture. Together, the generic LSB and the architecture-specific supplement for a single hardware architecture provide a complete interface specification for compiled application programs on systems that share a common hardware architecture.
This document is the architecture-specific supplement. It must be used in conjunction with the generic LSB. This document provides architecture-specific information that supplements the generic LSB as well as additional information that is not found in the generic LSB.
This document should be used in conjunction with the documents it references. This document enumerates the system components it includes, but descriptions of those components may be included entirely or partly in this document, partly in other documents, or entirely in other reference documents. For example, the section that describes system service routines includes a list of the system routines supported in this interface, formal declarations of the data structures they use that are visible to applications, and a pointer to the underlying referenced specification for information about the syntax and semantics of each call. Only those routines not described in standards referenced by this document, or extensions to those standards, are described in the detail. Information referenced in this way is as much a part of this document as is the information explicitly included here.
1.3. Related Standards
The specifications listed below are referenced in whole or in part by the Linux Standard Base. Such references may be normative or non-normative; a reference to specification shall only be considered normative if it is explicitly cited as such. The LSB may make normative references to a portion of these specifications (that is, to define a specific function or group of functions); in such cases, only the explicitly referenced portion of the specification is to be considered normative.

1.4. Relevant Libraries
The libraries listed here shall be available on a Linux Standard Base system. This list is an addition to the list in the general specification.
Table 1-2. Standard Library Names
Library	Runtime Name	
libm	libm.so.6.1	
libdl	libdl.so.2	
libcrypt	libcrypt.so.1	
libc	libc.so.6.1	
libpthread	libpthread.so.0	
proginterp	/lib/ld-lsb-ia64.so.1	

These libraries will be in an implementation-dependent directory which the dynamic linker will search by default.
1.5. How to Use this Standard
The complete LSB specification is composed of a generic LSB specification and this supplemental processor-specific specification. These two documents constitute a specification that should be used in conjunction with the publicly-available standards documents it references. The LSB enumerates the system components it includes, but descriptions of those components may be included entirely in the LSB, partly in the LSB and partly in other documents, or entirely in other reference documents.
1.6. Definitions
gLSB
 	The common part of the LSB Specification that describes those parts of the interface that remain constant across all hardware implementations of the LSB.
archLSB
 	The architectural part of the LSB Specification which describes the specific parts of the interface that are platform specific. The archLSB is complementary to the gLSB.
LSB Implementation Conformance 
 	An implementation satisfying the following requirements: 
	1.	The implementation shall implement fully the architecture described in the hardware manual for the target processor architecture. 
	2.	The implementation shall be capable of executing compiled applications having the format and using the system interfaces described in this document.
	3.	The implementation shall provide libraries containing the interfaces specified by this document, and shall provide a dynamic linking mechanism that allows these interfaces to be attached to applications at runtime. All the interfaces shall behave as specified in this document.
	4.	The map of virtual memory provided by the implementation shall conform to the requirements of this document. 
	5.	The implementation's low-level behavior with respect to function call linkage, system traps, signals, and other such activities shall conform to the formats described in this document. 
	6.	The implementation shall provide all of the mandatory interfaces in their entirety. 
	7.	The implementation may provide one or more of the optional interfaces. Each optional interface that is provided shall be provided in its entirety. The product documentation shall state which optional interfaces are provided. 
	8.	The implementation shall provide all files and utilities specified as part of this document in the format defined here and in other referenced documents. All commands and utilities shall behave as required by this document. The implementation shall also provide all mandatory components of an application's runtime environment that are included or referenced in this document. 
	9.	The implementation, when provided with standard data formats and values at a named interface, shall provide the behavior defined for those values and data formats at that interface. However, a conforming implementation may consist of components which are separately packaged and/or sold. For example, a vendor of a conforming implementation might sell the hardware, operating system, and windowing system as separately packaged items.
	10.	The implementation may provide additional interfaces with different names. It may also provide additional behavior corresponding to data values outside the standard ranges, for standard named interfaces.
LSB Application Conformance 
 	An application with the following characteristics: 
	1.	Its executable files are either shell scripts or object files in the format defined for the Object File Format system interface.
	2.	Its object files participate in dynamic linking as defined in the Program Loading and Linking System interface.
	3.	It employs only the instructions, traps, and other low-level facilities defined in the Low-Level System interface as being for use by applications.
	4.	If it requires any optional interface defined in this document in order to be installed or to execute successfully, the requirement for that optional interface is stated in the application's documentation. 
	5.	It does not use any interface or data format that is not required to be provided by a conforming implementation, unless: 
•	If such an interface or data format is supplied by another application through direct invocation of that application during execution, that application is in turn an LSB conforming application.
•	The use of that interface or data format, as well as its source, is identified in the documentation of the application. 
	6.	It must not use any values for a named interface that are reserved for vendor extensions. 
A strictly conforming application does not require or use any interface, facility, or implementation-defined extension that is not defined in this document in order to be installed or to execute successfully. 
Rationale 
 	An LSB conforming application is expected to have no dependencies on any vendor extensions to this document. The most common such extensions are additional function entry points and additional libraries other than the ones defined in this document. If an application requires such extensions, it is not portable, since other LSB conforming implementations may not provide those extensions. 
An LSB conforming application is required to use system services on the implementation on which it is running, rather than importing system routines from some other implementation. Thus, it must link dynamically to any routines in the implementation that perform system traps to kernel services. 
It is to be expected that some applications may be companion applications to other applications. For example, a query application may be a companion to a database application; a preprocessor may be an adjunct to one or more compilers; a data reformatter may convert data from one document manager to another. In such cases, the application may or may not be LSB conforming, regardless of whether the other application on which it is dependent is LSB conforming. If such an application merely uses data produced by another application, the application's compliance is independent of the other application's compliance. If such an application actually invokes another application during execution (as, for example, a third-party math library), the invoking application is LSB conforming only if it also constitutes a LSB conforming application in combination with the invoked application. 
Shell Script
 	A file that is read by an interpreter (e.g., awk). The first line of the shell script includes a reference to its interpreter binary.
1.7. Terminology
can
 	Describes a permissible optional feature or behavior available to the user or application. The feature or behavior is mandatory for an implementation that conforms to this document. An application can rely on the existence of the feature or behavior.
implementation-defined
 	Describes a value or behavior that is not defined by this document but is selected by an implementor. The value or behavior may vary among implementations that conform to this document. An application should not rely on the existence of the value or behavior. An application that relies on such a value or behavior cannot be assured to be portable across conforming implementations. The implementor shall document such a value or behavior so that it can be used correctly by an application.
may
 	Describes a feature or behavior that is optional for an implementation that conforms to this document. An application should not rely on the existence of the feature or behavior. An application that relies on such a feature or behavior cannot be assured to be portable across conforming implementations.
To avoid ambiguity, the opposite of may is expressed as need not, instead of may not.
must
 	Describes a feature or behavior that is mandatory for an application or user. An implementation that conforms to this document shall support this feature or behavior.
shall
 	Describes a feature or behavior that is mandatory for an implementation that conforms to this document. An application can rely on the existence of the feature or behavior.
should
 	For an implementation that conforms to this document, describes a feature or behavior that is recommended but not mandatory. An application should not rely on the existence of the feature or behavior. An application that relies on such a feature or behavior cannot be assured to be portable across conforming implementations.
For an application, describes a feature or behavior that is recommended programming practice for optimum portability.
undefined
 	Describes the nature of a value or behavior not defined by this document which results from use of an invalid program construct or invalid data input. The value or behavior may vary among implementations that conform to this document. An application should not rely on the existence or validity of the value or behavior. An application that relies on any particular value or behavior cannot be assured to be portable across conforming implementations.
unspecified
 	Describes the nature of a value or behavior not specified by this document which results from use of a valid program construct or valid data input. The value or behavior may vary among implementations that conform to this document. An application should not rely on the existence or validity of the value or behavior. An application that relies on any particular value or behavior cannot be assured to be portable across conforming implementations.
will
 	Same meaning as shall; shall is the preferred term.

II. Low Level System Information

Chapter 2. Machine Interface
2.1. Processor Architecture
The Itanium™ Architecture is specified by the following documents 
•	Itanium ™ Architecture Software Developer's Manual Volume 1: Application Architecture
•	Itanium ™ Architecture Software Developer's Manual Volume 2: System Architecture
•	Itanium ™ Architecture Software Developer's Manual Volume 3: Instruction Set Reference
•	IA-64 Processor Reference: Intel® Itanium ™ Processor Reference Manual for Software Development
•	Itanium ™ Software Conventions & Runtime Architecture Guide
•	Intel® Itanium ™ Processor-specific Application Binary Interface
Only the features of the Itanium™ processor instruction set may be assumed to be present. An application is responsible for determining if any additional instruction set features are available before using those additional features. If a feature is not present, then the application may not use it.
There are some features of the Itanium™ processor architecture that need not be supported by a conforming implementation. These are described in this chapter. A conforming application shall not rely on these features.
Applications conforming to this specification must provide feedback to the user if a feature that is required for correct execution of the application is not present. Applications conforming to this specification should attempt to execute in a diminished capacity if a required feature is not present.
This specfication does not provide any performance guarantees of a conforming system. A system conforming to this specification may be implemented in either hardware or software.
This specification describes only LP64 (i.e. 32-bit integers, 64-bit longs and pointers) based implementations. Implementations may also provide ILP32 (32-bit integers, longs, and pointers), but conforming applications shall not rely on support for ILP32. See section 1.2 of the Intel® Itanium ™ Processor-specific Application Binary Interface for further information.
2.2. Data Representation
See Itanium ™ Software Conventions & Runtime Architecture Guide Chapter 4.
Within this specification, the term byte refers to an 8-bit object, the term halfword refers to a 16-bit object, the term word refers to a 32-bit object, the term doubleword refers to a 64-bit object, and the term quadword refers to a 128-bit object. Although the Itanium™ architecture also supports 120-bit addressable objects, this specification does not require LSB-conforming implementations to provide support for these objects.
2.2.1. Byte Ordering
LSB-conforming applications shall use little-endian byte ordering. LSB-conforming implementations may support big-endian applications.
2.2.2. Fundamental Types
Table 2-1 describes how fundemental C language data types shall be represented: 
Table 2-1. Scalar Types
Type	C	sizeof	Alignment (bytes)	Notes	
Integral	char	1	1	
	
	signed char	

	
	unsigned char	

	
	short	2	2	
	
	signed short	

	
	unsigned short	

	
	int	4	4	
	
	signed int	

	
	unsigned int	

	
	long	8	8	
	
	signed long	

	
	unsigned long	

	
	long long	8	8	See Note Below	
	signed long long	

	
	unsigned long long	

	
Pointer	any-type *	8	8	
	
	any-type (*)()	

	
Floating-Point	float	4	4	
	
	double	8	8	
	
	long double	16	16	

	Support for the long long data type is dependent on support for ISO9899:1999 C language. This standard is not required for LSB-conformance, but this data type is important when developing applications for the Itanium™ architecture. The GNU Compiler Collection (gcc) includes support for long long of ISO9899:1999.
A null pointer (for all types) shall have the value zero.
2.2.3. Aggregates and Unions
Aggregates (structures and arrays) and unions assume the alignment of their most strictly aligned component. The size of any object, including aggregates and unions, shall always be a multiple of the object's alignment. An array uses the same alignment as its elements. Structure and union objects may require padding to meet size and element constraints. The contents of such padding is undefined. 
•	 An entire structure or union object shall be aligned on the same boundary as its most strictly aligned member. 
•	 Each member shall be assigned to the lowest available offset with the appropriate alignment. This may require internal padding, depending on the previous member. 
•	 A structure's size shall be increased, if necessary, to make it a multiple of the alignment. This may require tail padding, depending on the last member. 
A conforming application shall not read padding.

2.2.4. Bit Fields
C struct and union definitions may have bit-fields, which define integral objects with a specified number of bits.
Bit fields that are declared with neither signed nor unsigned specifier shall always be treated as unsigned. Bit fields obey the same size and alignment rules as other structure and union members, with the following additional properties: 
•	Bit-fields are allocated from right to left (least to most significant).
•	A bit-field must entirely reside in a storage unit for its appropriate type. A bit field shall never cross its unit boundary.
•	Bit-fields may share a storage unit with other struct/union members, including members that are not bit fields. Such other struct/union members shall occupy different parts of the storage unit.
•	The type of unnamed bit-fields shall not affect the alignment of a structure or union, although individual bit-field member offsets shall obey the alignment constraints.

LSB-conforming applications shall use the Process Startup as defined in Section 3.3.5 of the Intel® Itanium ™ Processor-specific Application Binary Interface.
5.1. Special Registers
Intel® Itanium ™ Processor-specific Application Binary Interface, section 3.3.5, defines required register initializations for process startup.
5.2. Process Stack (on entry)
As defined in Intel® Itanium ™ Processor-specific Application Binary Interface, section 3.3.5, the return pointer register (rp) shall contain a valid return address, such that if the application program returns from the main entry routine, the implementation shall cause the application to exit normally, using the returned value as the exit status. Further, the unwind information for this "bottom of stack" routine in the implementation shall provide a mechanism for recognizing the bottom of the stack during a stack unwind.
5.3. Auxiliary Vector
The auxiliary vector conveys information from the operating system to the application. Only the terminating null auxiliary vector entry is required, but if any other entries are present, they shall be interpreted as follows. This vector is an array of the following structures.
typedef struct
{
  long int a_type;              /* Entry type */
  union
    {
      long int a_val;           /* Integer value */
      void *a_ptr;              /* Pointer value */
      void (*a_fcn) (void);     /* Function pointer value */
    } a_un;
} auxv_t;
The application shall interpret the a_un value according to the a_type. Other auxiliary vector types are reserved.

	The auxiliary vector is intended for passing information from the operating system to a program interpreter, such as /lib/ld-lsb-ia64.so.1.
5.4. Environment
Although a pointer to the environment vector should be available as a third argument to the main entry point, conforming applications should use getenv to access the environment. (See The Single UNIX® Specification(SUS) Version 1 (UNIX 95) System Interfaces & Headers, Section exec).

Chapter 6. Coding Examples
LSB-conforming applications may implement fundamental operations using the Coding Examples as shown below.
Sample code sequences and coding conventions can be found in Itanium ™ Software Conventions & Runtime Architecture Guide, Chapter 9.

.sdata1	SHT_PROGBITS	SHF_ALLOC+SHF_WRITE+SHF_IA_64_SHORT	

.got
 	This section holds the Global Offset Table. See `Coding Examples' in Chapter 3, `Special Sections' in Chapter 4, and `Global Offset Table' in Chapter 5 of the processor supplement for more information.
.IA_64.archext
 	This section holds product-specific extension bits. The link editor will perform a logical "or" of the extension bits of each object when creating an executable so that it creates only a single .IA_64.archext section in the executable.
.IA_64.pltoff
 	This section holds local function descriptor entries.
.IA_64.unwind
 	This section holds the unwind function table. The contents are described in the Intel (r) Itanium (tm) Processor Specific ABI.
.IA_64.unwind_info
 	This section holds stack unwind and and exception handling information. The exception handling information is programming language specific, and is unspecified.
.plt
 	This section holds the Procedure Linkage Table.
.sbss
 	This section holds uninitialized data that contribute to the program''s memory image. Data objects contained in this section are recommended to be eight bytes or less in size. The system initializes the data with zeroes when the program begins to run. The section occupies no file space, as indicated by the section type SHT_NOBITS. The .sbss section is placed so it may be accessed using short direct addressing (22 bit offset from gp).
.sdata
 	This section and the .sdata1 section hold initialized data that contribute to the program''s memory image. Data objects contained in this section are recommended to be eight bytes or less in size. The .sdata and .sdata1 sections are placed so they may be accessed using short direct addressing (22 bit offset from gp).
.sdata1
 	See .sdata.
10.2. Linux Special Sections
The following Linux IA-64 specific sections are defined here. 
Table 10-2. Additional Special Sections
Name	Type	Attributes	
.rela.dyn	SHT_RELA	SHF_ALLOC	
.rela.IA_64.pltoff	SHT_RELA	SHF_ALLOC	

.rela.dyn
 	This section holds relocation information, as described in `Relocation'. These relocations are applied to the .dyn section.
.rela.IA_64.pltoff
 	This section holds relocation information, as described in `Relocation'. These relocations are applied to the .IA_64.pltoff section.
10.3. Section Types
Section Types are described in the Intel® Itanium ™ Processor-specific Application Binary Interface, Chapter 4.2. LSB conforming implementations are not required to use any sections in the range from SHT_IA_64_LOPSREG to SHT_IA_64_HIPSREG. Additionally, LSB conforming implementations are not required to support the SHT_IA_64_PRIORITY_INIT section, beyond the gABI requirements for the handling of unrecognized section types, linking them into a contiguous section in the object file created by the static linker.
10.4. Section Attribute Flags
See Intel® Itanium ™ Processor-specific Application Binary Interface, Chapter 4.2.2.
10.5. Special Section Types
See Intel® Itanium ™ Processor-specific Application Binary Interface, Chapter 4.2.3.

Chapter 11. Symbol Table
If an executable file contains a reference to a function defined in one of its associated shared objects, the symbol table section for that file shall contain an entry for that symbol. The st_shndx member of that symbol table entry contains SHN_UNDEF. This signals to the dynamic linker that the symbol definition for that function is not contained in the executable file itself. If that symbol has been allocated a procedure linkage table entry in the executable file, and the st_value member for that symbol table entry is non-zero, the value shall contain the virtual address of the first instruction of that procedure linkage table entry. Otherwise, the st_value member contains zero. This procedure linkage table entry address is used by the dynamic linker in resolving references to the address of the function. 
	Need to add something here about st_info and st_other ...

Chapter 12. Relocation
LSB-conforming applications shall use Relocations as defined in Intel® Itanium ™ Processor-specific Application Binary Interface, Chapter 4.3.

V. Base Libraries

Chapter 16. Libraries
An LSB-conforming implementation shall support base libraries which provide interfaces for accessing the operating system, processor and other hardware in the system.
Only those interfaces that are unique to the Itanium™ platform are defined here. This section should be used in conjunction with the corresponding section in the Linux Standard Base Specification.
An LSB conforming implementation need not define an Unwind library interface as required by the Intel® Itanium ™ Processor-specific Application Binary Interface. If such an interface is provided, it shall conform to the specification in the Intel® Itanium ™ Processor-specific Application Binary Interface. A conforming application shall not depend on this interface.

16.2. Data Definitions for libc
This section contains standard data definitions that describe system data. These definitions are organized into groups that correspond to system headers. This convention is used as a convenience for the reader, and does not imply the existence of these headers, or their content.
ISO C serves as the LSB reference programming language, and data definitions are specified in ISO C format. The C language is used here as a convenient notation. Using a C language description of these data objects does not preclude their use by other programming languages.

Appendix A. Alphabetical Listing of Interfaces

Appendix B. GNU Free Documentation License
Version 1.1, March 2000
Copyright (C) 2000 Free Software Foundation, Inc. 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA Everyone is permitted to copy and distribute verbatim copies of this license document, but changing it is not allowed.
B.1. PREAMBLE
The purpose of this License is to make a manual, textbook, or other written document "free" in the sense of freedom: to assure everyone the effective freedom to copy and redistribute it, with or without modifying it, either commercially or noncommercially. Secondarily, this License preserves for the author and publisher a way to get credit for their work, while not being considered responsible for modifications made by others.
This License is a kind of "copyleft", which means that derivative works of the document must themselves be free in the same sense. It complements the GNU General Public License, which is a copyleft license designed for free software.
We have designed this License in order to use it for manuals for free software, because free software needs free documentation: a free program should come with manuals providing the same freedoms that the software does. But this License is not limited to software manuals; it can be used for any textual work, regardless of subject matter or whether it is published as a printed book. We recommend this License principally for works whose purpose is instruction or reference.
B.2. APPLICABILITY AND DEFINITIONS
This License applies to any manual or other work that contains a notice placed by the copyright holder saying it can be distributed under the terms of this License. The "Document", below, refers to any such manual or work. Any member of the public is a licensee, and is addressed as "you".
A "Modified Version" of the Document means any work containing the Document or a portion of it, either copied verbatim, or with modifications and/or translated into another language.
A "Secondary Section" is a named appendix or a front-matter section of the Document that deals exclusively with the relationship of the publishers or authors of the Document to the Document's overall subject (or to related matters) and contains nothing that could fall directly within that overall subject. (For example, if the Document is in part a textbook of mathematics, a Secondary Section may not explain any mathematics.) The relationship could be a matter of historical connection with the subject or with related matters, or of legal, commercial, philosophical, ethical or political position regarding them.
The "Invariant Sections" are certain Secondary Sections whose titles are designated, as being those of Invariant Sections, in the notice that says that the Document is released under this License.
The "Cover Texts" are certain short passages of text that are listed, as Front-Cover Texts or Back-Cover Texts, in the notice that says that the Document is released under this License.
A "Transparent" copy of the Document means a machine-readable copy, represented in a format whose specification is available to the general public, whose contents can be viewed and edited directly and straightforwardly with generic text editors or (for images composed of pixels) generic paint programs or (for drawings) some widely available drawing editor, and that is suitable for input to text formatters or for automatic translation to a variety of formats suitable for input to text formatters. A copy made in an otherwise Transparent file format whose markup has been designed to thwart or discourage subsequent modification by readers is not Transparent. A copy that is not "Transparent" is called "Opaque".
Examples of suitable formats for Transparent copies include plain ASCII without markup, Texinfo input format, LaTeX input format, SGML or XML using a publicly available DTD, and standard-conforming simple HTML designed for human modification. Opaque formats include PostScript, PDF, proprietary formats that can be read and edited only by proprietary word processors, SGML or XML for which the DTD and/or processing tools are not generally available, and the machine-generated HTML produced by some word processors for output purposes only.
The "Title Page" means, for a printed book, the title page itself, plus such following pages as are needed to hold, legibly, the material this License requires to appear in the title page. For works in formats which do not have any title page as such, "Title Page" means the text near the most prominent appearance of the work's title, preceding the beginning of the body of the text.
B.3. VERBATIM COPYING
You may copy and distribute the Document in any medium, either commercially or noncommercially, provided that this License, the copyright notices, and the license notice saying this License applies to the Document are reproduced in all copies, and that you add no other conditions whatsoever to those of this License. You may not use technical measures to obstruct or control the reading or further copying of the copies you make or distribute. However, you may accept compensation in exchange for copies. If you distribute a large enough number of copies you must also follow the conditions in section 3.
You may also lend copies, under the same conditions stated above, and you may publicly display copies.
B.4. COPYING IN QUANTITY
If you publish printed copies of the Document numbering more than 100, and the Document's license notice requires Cover Texts, you must enclose the copies in covers that carry, clearly and legibly, all these Cover Texts: Front-Cover Texts on the front cover, and Back-Cover Texts on the back cover. Both covers must also clearly and legibly identify you as the publisher of these copies. The front cover must present the full title with all words of the title equally prominent and visible. You may add other material on the covers in addition. Copying with changes limited to the covers, as long as they preserve the title of the Document and satisfy these conditions, can be treated as verbatim copying in other respects.
If the required texts for either cover are too voluminous to fit legibly, you should put the first ones listed (as many as fit reasonably) on the actual cover, and continue the rest onto adjacent pages.
If you publish or distribute Opaque copies of the Document numbering more than 100, you must either include a machine-readable Transparent copy along with each Opaque copy, or state in or with each Opaque copy a publicly-accessible computer-network location containing a complete Transparent copy of the Document, free of added material, which the general network-using public has access to download anonymously at no charge using public-standard network protocols. If you use the latter option, you must take reasonably prudent steps, when you begin distribution of Opaque copies in quantity, to ensure that this Transparent copy will remain thus accessible at the stated location until at least one year after the last time you distribute an Opaque copy (directly or through your agents or retailers) of that edition to the public.
It is requested, but not required, that you contact the authors of the Document well before redistributing any large number of copies, to give them a chance to provide you with an updated version of the Document.
B.5. MODIFICATIONS
You may copy and distribute a Modified Version of the Document under the conditions of sections 2 and 3 above, provided that you release the Modified Version under precisely this License, with the Modified Version filling the role of the Document, thus licensing distribution and modification of the Modified Version to whoever possesses a copy of it. In addition, you must do these things in the Modified Version:
	A.	Use in the Title Page  (and on the covers, if any) a title distinct from that of the  Document, and from those of previous versions (which should, if  there were any, be listed in the History section of the  Document). You may use the same title as a previous version if  the original publisher of that version gives permission.
	B.	List on the Title Page,  as authors, one or more persons or entities responsible for  authorship of the modifications in the Modified Version,  together with at least five of the principal authors of the  Document (all of its principal authors, if it has less than  five).
	C.	State on the Title page  the name of the publisher of the Modified Version, as the  publisher.
	D.	Preserve all the  copyright notices of the Document.
	E.	Add an appropriate  copyright notice for your modifications adjacent to the other  copyright notices.
	F.	Include, immediately  after the copyright notices, a license notice giving the public  permission to use the Modified Version under the terms of this  License, in the form shown in the Addendum below.
	G.	Preserve in that license  notice the full lists of Invariant Sections and required Cover  Texts given in the Document's license notice.
	H.	Include an unaltered  copy of this License.
	I.	Preserve the section  entitled "History", and its title, and add to it an item stating  at least the title, year, new authors, and publisher of the  Modified Version as given on the Title Page. If there is no  section entitled "History" in the Document, create one stating  the title, year, authors, and publisher of the Document as given  on its Title Page, then add an item describing the Modified  Version as stated in the previous sentence.
	J.	Preserve the network  location, if any, given in the Document for public access to a  Transparent copy of the Document, and likewise the network  locations given in the Document for previous versions it was  based on. These may be placed in the "History" section. You  may omit a network location for a work that was published at  least four years before the Document itself, or if the original  publisher of the version it refers to gives permission.
	K.	In any section entitled  "Acknowledgements" or "Dedications", preserve the section's  title, and preserve in the section all the substance and tone of  each of the contributor acknowledgements and/or dedications  given therein.
	L.	Preserve all the  Invariant Sections of the Document, unaltered in their text and  in their titles. Section numbers or the equivalent are not  considered part of the section titles.
	M.	Delete any section  entitled "Endorsements". Such a section may not be included in  the Modified Version.
	N.	Do not retitle any  existing section as "Endorsements" or to conflict in title with  any Invariant Section.
If the Modified Version includes new front-matter sections or appendices that qualify as Secondary Sections and contain no material copied from the Document, you may at your option designate some or all of these sections as invariant. To do this, add their titles to the list of Invariant Sections in the Modified Version's license notice. These titles must be distinct from any other section titles.
You may add a section entitled "Endorsements", provided it contains nothing but endorsements of your Modified Version by various parties--for example, statements of peer review or that the text has been approved by an organization as the authoritative definition of a standard.
You may add a passage of up to five words as a Front-Cover Text, and a passage of up to 25 words as a Back-Cover Text, to the end of the list of Cover Texts in the Modified Version. Only one passage of Front-Cover Text and one of Back-Cover Text may be added by (or through arrangements made by) any one entity. If the Document already includes a cover text for the same cover, previously added by you or by arrangement made by the same entity you are acting on behalf of, you may not add another; but you may replace the old one, on explicit permission from the previous publisher that added the old one.
The author(s) and publisher(s) of the Document do not by this License give permission to use their names for publicity for or to assert or imply endorsement of any Modified Version.
B.6. COMBINING DOCUMENTS
You may combine the Document with other documents released under this License, under the terms defined in section 4 above for modified versions, provided that you include in the combination all of the Invariant Sections of all of the original documents, unmodified, and list them all as Invariant Sections of your combined work in its license notice.
The combined work need only contain one copy of this License, and multiple identical Invariant Sections may be replaced with a single copy. If there are multiple Invariant Sections with the same name but different contents, make the title of each such section unique by adding at the end of it, in parentheses, the name of the original author or publisher of that section if known, or else a unique number. Make the same adjustment to the section titles in the list of Invariant Sections in the license notice of the combined work.
In the combination, you must combine any sections entitled "History" in the various original documents, forming one section entitled "History"; likewise combine any sections entitled "Acknowledgements", and any sections entitled "Dedications". You must delete all sections entitled "Endorsements."
B.7. COLLECTIONS OF DOCUMENTS
You may make a collection consisting of the Document and other documents released under this License, and replace the individual copies of this License in the various documents with a single copy that is included in the collection, provided that you follow the rules of this License for verbatim copying of each of the documents in all other respects.
You may extract a single document from such a collection, and distribute it individually under this License, provided you insert a copy of this License into the extracted document, and follow this License in all other respects regarding verbatim copying of that document.
B.8. AGGREGATION WITH INDEPENDENT WORKS
A compilation of the Document or its derivatives with other separate and independent documents or works, in or on a volume of a storage or distribution medium, does not as a whole count as a Modified Version of the Document, provided no compilation copyright is claimed for the compilation. Such a compilation is called an "aggregate", and this License does not apply to the other self-contained works thus compiled with the Document, on account of their being thus compiled, if they are not themselves derivative works of the Document.
If the Cover Text requirement of section 3 is applicable to these copies of the Document, then if the Document is less than one quarter of the entire aggregate, the Document's Cover Texts may be placed on covers that surround only the Document within the aggregate. Otherwise they must appear on covers around the whole aggregate.
B.9. TRANSLATION
Translation is considered a kind of modification, so you may distribute translations of the Document under the terms of section 4. Replacing Invariant Sections with translations requires special permission from their copyright holders, but you may include translations of some or all Invariant Sections in addition to the original versions of these Invariant Sections. You may include a translation of this License provided that you also include the original English version of this License. In case of a disagreement between the translation and the original English version of this License, the original English version will prevail.
B.10. TERMINATION
You may not copy, modify, sublicense, or distribute the Document except as expressly provided for under this License. Any other attempt to copy, modify, sublicense or distribute the Document is void, and will automatically terminate your rights under this License. However, parties who have received copies, or rights, from you under this License will not have their licenses terminated so long as such parties remain in full compliance.
B.11. FUTURE REVISIONS OF THIS LICENSE
The Free Software Foundation may publish new, revised versions of the GNU Free Documentation License from time to time. Such new versions will be similar in spirit to the present version, but may differ in detail to address new problems or concerns. See http://www.gnu.org/copyleft/.
Each version of the License is given a distinguishing version number. If the Document specifies that a particular numbered version of this License "or any later version" applies to it, you have the option of following the terms and conditions either of that specified version or of any later version that has been published (not as a draft) by the Free Software Foundation.

Appendix C. Build Environment
C.1. Introduction
This section is informative, and carries no normative requirements on the Itanium™ Application Binary Interface. The interfaces described here should be available in an Itanium™ LSB Build Environment. An LSB Build Environment is a platform on which LSB conforming applications can be built from source code. Platforms providing an LSB Build Environment need not provide an LSB Runtime Environment.
C.2. Build Environment
A conforming LSB Build Environment should provide a compiler capable of producing objects that conform to this standard.
Such a compiler should provide the following predefined symbols, pre-processor assertions, and compiler pragmas.
C.2.1. Pre-Defined Preprocessor Symbols
Table C-1. Pre-Defined Preprocessor Symbols
Symbol	Description	
__ia64	This symbol should be used when testing for the target architecture at compile time. The initial value shall be 1. Further information on the architecture can be determined from the ELF header flags.	
_LP64	Value is defined as 1. The architecture supports 64 bit longs, long longs, and pointers. Integers are 32 bit.	

	The gcc compiler currently pre-defines the symbol __LP64__, but not the symbol _LP64. The gcc team are aware of this deficiency.
C.2.2. Pre-Defined Preprocessor Assertions
Preprocessor assertions are deprecated, and conforming applications should not require any preprocessor assertion support. LSB Conforming Build Environments are not required to provide any predefined preprocessor assertions.
	The Intel® Itanium ™ Processor-specific Application Binary Interface requires preprocessor assertion support. However, this feature is deprecated in some compilers (most notably gcc), and applications should not use it.
C.2.3. Compiler Pragmas
The Intel® Itanium ™ Processor-specific Application Binary Interface, chapter 7.2.3, defines a number of compiler pragmas specific to the Intel Itanium™ compiler. These pragmas are not required to be supported by other compilers.
C.3. ILP32 ABI
Support for the IA32/ILP32 ABI is optional. See Intel® Itanium ™ Processor-specific Application Binary Interface Chapter 7.3.
C.4. Synchronization Primitives
The synchronization primitives listed below should be available to applications in the LSB Build Environment for Itanium™. These intrinsic functions need not be provided in any system library, and the compiler may treat these as inline functions in all cases. See Intel® Itanium ™ Processor-specific Application Binary Interface, Chapter 7.4 for details. 
Table C-2. Intrinsic Functions
Symbol	Description	
__sync_fetch_and_add	Atomically add a value to a referenced location and return the previous value	
__sync_fetch_and_sub	Atomically subtract a value from a referenced location and return the previous value	
__sync_fetch_and_or	Atomically bitwise or a value with a referenced location and return the previous value	
__sync_fetch_and_and	Atomically bitwise and a value with a referenced location and return the previous value	
__sync_fetch_and_xor	Atomically bitwise exclusive or a value with a referenced location and return the previous value	
__sync_fetch_and_nand	Atomically bitwise not-and a value with a referenced location and return the previous value	
__sync_add_and_fetch	Atomically add a value to a referenced location and return the new value	
__sync_sub_and_fetch	Atomically subtract a value from a referenced location and return the new value	
__sync_or_and_fetch	Atomically bitwise or a value with a referenced location and return the new value	
__sync_and_and_fetch	Atomically bitwise and a value with a referenced location and return the new value	
__sync_xor_and_fetch	Atomically bitwise exclusive or a value with a referenced location and return the new value	
__sync_nand_and_fetch	Atomically bitwise not-and a value with a referenced location and return the new value	
__sync_bool_compare_and_swap	Atomically compare a referenced location with a given value. If equal, replace the contents of the location with a new value, and return 1 (true), otherwise return 0 (false).	
__sync_val_compare_and_swap	Atomically compare a referenced location with a given value. If equal, replace the contents of the location with a new value. Return the resulting value.	
__sync_synchronize	A synchronization point.	
__sync_lock_test_and_set	Atomically set a referenced location to a value and return the old value. Acquire a lock on the referenced location.	
__sync_lock_release	Release a lock acquired previously.
