Overview

XL C/C++ Advanced Edition for Linux™, V9.0, a highly advanced optimizing compiler for the Linux distributions — Red Hat Enterprise Linux AS 5 for IBM POWER™ and SUSE Linux Enterprise Server 10 Service Pack 1 for IBM POWER — runs on the PowerPC® architecture, including the POWER6™ processors. The compiler is an industry standards-based professional programming tool that can be used for developing large, complex, computationally intensive 32-bit and 64-bit applications in the C and C++ programming languages.

XL C/C++ Advanced Edition for Linux, V9.0 is the follow-on release to XL C/C++ Advanced Edition V8.0 for Linux. The XL family of IBM compilers now includes XL C/C++ Enterprise Edition (AIX® and PASE), XL C Enterprise Edition (AIX and PASE), XL C/C++ Advanced Edition (Linux), XL C/C++ Advanced Edition (Blue Gene®/L), XL C/C++ (z/OS®), XL Fortran Enterprise Edition (AIX and PASE), XL Fortran Advanced Edition (Linux), and XL Fortran Advanced Edition (Blue Gene/L). The C/C++ family of products also includes C/C++ for z/VM®.

The XL C/C++ compiler can optimize and tune your application code for execution on IBM System p™ servers supporting the POWER4™, POWER5™, POWER6, and PowerPC architectures, including the PowerPC 970 processor within the IBM BladeCenter® JS20 and BladeCenter JS21. With the V9.0 release, the XL C/C++ compiler exploits, optimizes, and tunes the latest POWER6 architecture for the System p5™ servers and PowerPC processor-based blades.

Description

The XL C/C++ compiler continues to deliver additional functionality and enhancements, especially in the areas of performance and optimization, support for language enhancements, and support for new processors.

Support for the new POWER6 processors

With V9.0, the XL C/C++ compiler exploits, optimizes and tunes for the latest POWER6 processors. XL C/C++ V9.0 expands the list of -qarch and -qtune suboptions to support the newly available POWER6 processors.

Default language level change for C — extc99

The default -qlanglvl compiler option setting is now extc99 when invoking the C compiler with the xlc invocation. This change will allow you to use C99 features and headers without having to explicitly specify the extc99 suboption.

You can revert to previous xlc behavior by specifying -qlanglvl=extc89 when invoking the compiler.

Architecture and processor support

The -qarch and -qtune compiler options control the code generated by the compiler. These compiler options adjust the instructions, scheduling, and other optimizations for a specified target processor or range of processors.

New default setting for -qtune: -qtune=balanced: The -qtune=balanced suboption is new for this release and becomes the default -qtune setting when certain -qarch settings are specified. Using -qtune=balanced instructs the compiler to tune generated code across a range of recent processor architectures, including POWER6.

New compiler options for POWER6 processors

  • -qarch=pwr6
  • -qarch=pwr6e
  • -qtune=pwr6

The -qipa compiler option also adds a new architecture cloning suboption, -qipa=clonearch=pwr6, to support interprocedural analysis optimizations on POWER6 processors.

Additional enhancements

  • XL C/C++ V9.0 introduces many new performance-related compiler options and directives.
  • New built-in functions for this release include PowerPC cache control and POWER6 prefetch extensions and cache control.
