| Overview |
|
IBM C for AIX®, V6.0 is a command-line C compiler for the AIX operating system. Libraries and tools shipped with the compiler help you to effectively create high-performance and complex programs. The IBM Distributed Debugger shipped with the compiler allows you to visually debug programs running locally, remotely or in a client-server environment. Extensive online help ensures that you can easily access the information you need for using C for AIX.
The C for AIX compiler builds on the AIX operating system and the PowerPC® architecture to offer efficient compiler options and built-in functions. It also allows users to compile industry-standard, compliant programs for running on 32-bit and 64-bit environments.
What's New in V6?
- Conformance to the latest C99 industry standard
- New compiler options and pragmas for increased efficiency
- Optimizations exploiting the PowerPC Architecture™
- Support for a subset of features related to GNU C
- Enhanced language level support
With this announcement, program services for C for AIX, V5.0 (product number 5765-E32, part number
41L3102) are extended to December 31, 2003.

| Description |
|
The C for AIX, V6.0 software is a highly productive and powerful development environment for building C applications.
1999 C Standard
The IBM C for AIX, V6.0 program builds on official industry standards, so your code can be ported easily.
The ISO/IEC 9899:1999 International Standard (also known as C99) specifies the form and establishes the interpretation of programs written in the C programming language. This is the second edition of the standard. This update is designed to enhance the capability of the C language, provide clarifications, and incorporate technical corrections to the previous edition of the standard. Not all run-time functions and facilities required by the ISO/IEC 9899:1999 International Standard are supported on all the operating system levels that can run this version of the compiler. The availability of system header files provides an indication of the support.
The first edition, which is supported by C for AIX, V6.0, is ISO/IEC 9899:1990 (also known as C89). With representation from IBM's compiler development team on the ANSI C committee, IBM is in a position to understand the latest changes and clarifications to the C programming language standard.
The C99 standard offers a number of additional language functions including:
- Long Long
- Bool
- Pragma operator
- Initializer allow con
- Empty new argument
- Macro with variable number of args
- Inline function specifier
- Complex
This international standard is designed to promote the portability of C programs among a variety of implementations.
The -qlanglvl compiler option has been enhanced to support all of the available language levels that you can use to compile your code within C for AIX. These include the strict conformance to the latest C99 standard, extended conformance to C99, conformance to the previous C89 standard or enabling of C99 with the universal character set. C for AIX offers you the flexibility to compile your code to the language level that you need.
Support for a Subset of Features Related to GNU C
GCC is an open-source compiler collection for C, C++, Fortran, Objective C, and other languages. To help with the porting of code that was originally written for GCC, a subset of features related to GNU C are supported by C for AIX. Other GNU C features are recognized (accepted and ignored). This will help you minimize the number of changes that you need to make to your GCC source code to ensure that it compiles successfully using C for AIX.
32-bit and 64-bit Application Development
You can use C for AIX to develop 32-bit and 64-bit applications. C for AIX provides 64-bit pointer and 64-bit addressability support for SMP and serial code. High optimization levels, interprocedural analysis, and SMP are supported for 64-bit code.
Optimizations Exploiting the PowerPC Architecture
C for AIX, V6.0 supports the PowerPC architecture (includes the POWER4 architecture) of the RS/6000. The new -qarch=pwr4 and -qtune=pwr4 suboptions support POWER4 architecture. The -qarch=pwr4 suboption allows the compiler to exploit the instruction set of POWER4 and generate code optimized for this latest architecture. The -qtune=pwr4 suboption instructs the compiler to tune the optimizations of the generated code to the POWER4 architecture.
C for AIX, V6.0 also supports a number of special built-in functions for the PowerPC architecture.
New Compiler Options and Pragmas
C for AIX, V6.0 introduces a number of new compiler options and pragmas for ease of development and increased efficiency in compilation.
-
New compiler options include:
- New -qhot option — determines whether to perform high-order transformations on loops and array language during optimization and whether to pad array dimensions and data objects to avoid cache misses.
- New -qarch=pwr4 suboption — supports POWER4 architecture.
- New -qtune=pwr4 suboption — supports POWER4 architecture.
- New -qtocmerge option — enables the TOC merge feature in C for AIX. This feature maps data items to absolute addresses by means of an import file.
- New -qreport option — determines whether to produce transformation reports showing how the program is made parallel and how loops are optimized.
- New -qipa=threads suboption — used for threaded interprocedural analysis.
- The -qlargepage — a new option to support the new POWER4 architecture's support of large 16 M pages, in addition to the default 4 K pages.
- New -qsmallstack optimization option — intended to reduce the size of the stack frame.
- New -qunwind optimization option — reduces the number of saves and restores of volatile registers on the most common paths through a function.
-
New pragmas include:
- New #pragmas execution_frequency (very_low) directive — specifies infrequently executed code.
- New #pragma snapshot directive — sets a debugging breakpoint at the point of the pragma, and defines a list of variables to examine when program execution reaches that point.
- New #pragma pack directive — allows the user to modify the alignment rule for members of structures.
Comprehensive Help System
C for AIX help is online and in HTML format, so if you've browsed the World Wide Web, you already know how to use it effectively. This online help provides you with information on every component in C for AIX. It is optimized for fast access to information, and gives you fuzzy and precise full-text search. Most information is also provided in Adobe Acrobat PDF format.
Text help is also available directly on your command line. This help will give you a quick
reference for the format and argument description for all C compiler options.
