XL C/C++ is a standards-based, high performance C and C++ compiler with advanced optimizing and debugging features.
It gives you the ability to optimize and tune applications for optimal execution on systems using PowerPC, POWER3, POWER4, POWER5, and the latest POWER6 processors from IBM.
- Supports IBM System p systems capable of running IBM AIX 5L Version 5.2 and IBM AIX 5L Version 5.3
- Also supports System i servers capable of running i5/OS V5R3 and i5/OS Portable Application Solutions Environment (PASE)
- Features a wide range of optimizing features that let you generate highly-optimized 32-bit or 64-bit application code to run efficiently on a wide variety of processors and processor families, or you can tune generated code to run most efficiently on a specific processor or processor family
- Supports the OpenMP API Version 2.5 specification, and related compiler options let you exploit symmetric multiprocessing (SMP) architectures with automatic parallelization of C and C++ program code as well as explicit parallelization of specifically selected sections of program code
- Provides options to support application debugging with standard symbolic debugging tools
- Also includes facilities to help you port application code from GNU C/C++
