Microsoft Visual C, C++ Compiler
The 64-bit build environment in the release of the Microsoft® Windows® Server 2003 DDK includes a 64-bit compiler you can use to build and test 64-bit driver code that runs on AMD64 processors. The following sections describe the AMD64-specific aspects of this compiler.

Microsoft Visual C/C++ Compiler Intrinsics Documentation
This Compiler Intrinsics document described those functions that are built-in (鈥渋ntrinsics鈥? to the compiler. Use of intrinsics can make code faster and more portable (compared to inline assembly) and intrinsics are especially useful for 64-bit Windows development as inline assembly is not supported. This document provides detailed descriptions on the intrinsics available for the AMD64 architecture.

Using Compiler and Linker Options to Build for Performance
Experiment with, evaluate, and then use 64-bit Windows VC/C++ compiler and linker options for maximum leverage of the AMD64 architecture target.

/fp:fast - Use when floating point performance matters most
/GL - Compiler-Time Whole Program Optimization
/LTCG - Link-Time Code Generation
/O2 - Optimize for Speed (and very safe)
Compiling with /GL and linking with /LTCG gives PGO (Profile Guided Optimization).

For more information regarding compiler and linker optimizations and options, see the "Visual C++ Whidbey: Advanced Code Generation" presentation at http://msdn.microsoft.com/visualc/whidbey/.

Absoft Pro Fortran v8.2
The Absoft Pro Fortran Compiler for Windows (32-bit) is the most complete tool kit available for Windows Fortran developers. Included are F95/F77 Fortran compilers, a C/C++ compiler, an Integrated Development Environment, graphics, and the multi-language Fx2™ Debugger all in one package. Pro Fortran compilers generate superior 32-bit application performance on AMD Athlon processors. A 64-bit version is in development for Windows, and available now for AMD64 Linux.
