| Overview |
|
IBM XL C Enterprise Edition V8.0 for AIX® is an optimizing, standards-based compiler for the AIX operating system running on the PowerPC® architecture. The compiler is a professional programming tool for creating and maintaining 32- and 64-bit applications in the C programming language.
The XL family of IBM compilers includes XL C Enterprise Edition (AIX and PASE), XL C/C++ Enterprise Edition (AIX and PASE), XL Fortran Enterprise Edition (AIX and PASE). The C/C++ family of products also includes z/OS® C/C++ and C/C++ for z/VM®.
The XL C compiler optimizes and tunes your application code for superior execution on RS/6000® and System p5™ and pSeries® servers supporting the POWER3™, POWER4™, POWER5™, and PowerPC architectures. This AIX product will also run on i5/OS™ PASE.
With V8.0, the XL C compiler will exploit, optimize, and tune the latest POWER5+™ architecture in
the IBM 
pSeries machines.
In addition, it will also exploit, optimize, and tune for the PowerPC 970 processor within the
IBM eServer® BladeCenter JS20. The XL C compiler also supports the POWER4 and POWER5
architectures on IBM eServer iSeries™ with the i5/OS Portable Application Solutions Environment
(i5/OS PASE).
XL C Enterprise Edition V8.0 for AIX adds a number of features to make it easier for programmers to write complex applications that have high performance.

| Description |
|
XL C Enterprise Edition for AIX, the IBM C compiler continues to improve, especially in the categories of performance and optimization, and conformance to industry standards and ease of use.
Optimizations exploiting the latest POWER5+ processors
XL C Enterprise Edition V8.0 for AIX offers a number of new optimization and performance-tuning features and enhancements that exploit all PowerPC systems, including the latest POWER5+ hardware architectures. The -qarch compiler option controls the particular instructions that are generated for the specified machine architecture. The -qtune compiler option adjusts the instructions, scheduling, and other optimizations to enhance performance on the specified hardware. These options work together to generate application code that gives the best performance for the specified architecture.
XL C Enterprise Edition V8.0 for AIX augments the list of suboptions available to the -qarch compiler option to support the newly-available POWER5+ processors and processors that support the VMX instruction set. The following new -qarch options are available:
- -qarch=pwr5x
- -qarch=ppc64v
High-performance libraries
XL C Enterprise Edition for AIX includes highly-tuned mathematical functions that can greatly improve the performance of mathematically-intensive applications. These functions are provided through the following high-performance libraries:
MASS: MASS libraries provide high-performance scalar and vector functions to perform common mathematical computations. The MASS libraries included with XL C Enterprise Edition V8.0 for AIX introduce new scalar and vector functions, and new support for the POWER5 processor architecture.
BLAS: XL C Enterprise Edition V8.0 for AIX introduces the BLAS set of high- performance algebraic functions. You can use these functions to:
- Compute the matrix-vector product for a general matrix or its transpose
- Perform combined matrix multiplication and addition for general matrices or their transposes
VMX support
XL C now supports vector multimedia extension (VMX) instructions and the Altivec programming model.
Objects compiled with vector data types and related operations can run on systems with processor architectures and operating systems (AIX 5L for POWER V5.3 with the 5300-03 Recommended Maintenance Package required) that support the single instruction, multiple data (SIMD) instruction set. The SIMD instruction set (also known as vector multimedia extension or VMX instructions) enables higher utilization of microprocessor hardware and supports performing calculations in parallel. The compiler provides the ability to automatically enable SIMD vectorization at higher levels of optimizations. This release of XL C introduces several new option and suboption combinations to enable and exploit VMX instructions.
Other performance-related compiler options and directives
A number of compiler options and directives have been enhanced in this release. In addition this release adds a number of new built-in functions for the POWER and PowerPC architectures.
OpenMP API V2.5 support for C, C++ and Fortran
XL C now supports the OpenMP API V2.5 standard. This latest level of the OpenMP specification combines the previous C/C++ and Fortran OpenMP specifications into one single specification for both C/C++ and Fortran, and resolves previous inconsistencies between them.
XL C builds on official industry standards, so your code can be ported easily among a variety of platforms and implementations. The OpenMP API is a portable, scalable programming model that provides a standard interface for developing user-directed shared-memory parallelization in C, C++, and Fortran applications. The specification is defined by the OpenMP organization, a group of computer hardware and software vendors, including IBM.
For more information about the OpenMP specification, visit the OpenMP Web site at
Ease of use
XL C includes the following new features to help you more easily use the compiler for your application development:
Support for IBM Tivoli License Manager: IBM Tivoli License Manager (ITLM) is a Web-based solution that can help you manage software usage metering and license allocation services on supported systems. In general, ITLM recognizes and monitors the products that are installed and in use on your system.
XL C Enterprise Edition V8.0 for AIX is ITLM-enabled for inventory support only, which means that ITLM is able to detect product installation of XL C, but not its usage.
Note that ITLM is not a part of the XL C compiler offering, and must be licensed and installed separately.
Once installed and activated, ITLM scans your system for product inventory signatures that indicate whether a given product is installed on your system. ITLM also identifies that product's version, release, and modification levels.
Section 508 of the U.S. Rehabilitation Act
XL C Enterprise Edition V8.0 for AIX is capable as of October 14, 2005, when used in accordance with IBM's associated documentation, of satisfying the applicable requirements of Section 508 of the Rehabilitation Act, provided that any assistive technology used with the product properly interoperates with it. A US Section 508 Voluntary Product Accessibility Template (VPAT) can be requested via IBM's web site at

| Product positioning |
|
XL C Enterprise Edition V8.0 for AIX is part of the IBM family of C and C++ compilers that support a number of platforms (IBM and non-IBM). It joins XL C/C++ Enterprise Edition for AIX on the pSeries, XL C/C++ for Linux™ on iSeries and pSeries, C/C++ for z/OS, ILE C/C++ for OS/400® on iSeries, and C/C++ for z/VM. The code base for all of these compilers (C and C++) is the same. This will make source-level portability of your applications from these platforms to AIX easier than ever before.
In addition, the C compiler supports the latest ISO C 1999 (International Standard ISO/IEC 9899:1999) standard. XL C Enterprise Edition V8.0 for AIX has included the latest C standard committee technical report for Unicode support. With representation from IBM compiler development team on the ISO/ANSI C committee, IBM is in a position to understand the latest updates, clarifications, and recommendations to the C standards. Support of programming language standards allows for maximum portability of your source code among a variety of compiler implementations.
