Compiler and Assembler Support
Recent releases of GCC starting with version 4.6 (although there was a 4.3 branch with certain support) and the Intel Compiler Suite starting with version 11.1 support AVX. The Visual Studio 2010/2012 compiler supports AVX via intrinsic and /arch:AVX switch. The Open64 compiler version 4.5.1 supports AVX with -mavx flag. PathScale supports via the -mavx flag. The Vector Pascal compiler supports AVX via the -cpuAVX32 flag. The GNU Assembler (GAS) inline assembly functions support these instructions (accessible via GCC), as do Intel primitives and the Intel inline assembler (closely compatible to GAS, although more general in its handling of local references within inline code). Other assemblers such as MASM VS2010 version, YASM 1.1.0, FASM, NASM and JWASM also apparently support AVX instructions.

Famous quotes containing the word support:
“They [parents] can help the children work out schedules for homework, play, and television that minimize the conflicts involved in what to do first. They can offer moral support and encouragement to persist, to try again, to struggle for understanding and mastery. And they can share a child’s pleasure in mastery and accomplishment. But they must not do the job for the children.”
—Dorothy H. Cohen (20th century)
