Intel C++ Compiler 11.0 (Default branch)
The Intel C++ Compiler for Linux is a full fledged C/C++ compiler and debugger suite. Its aim is to provide outstanding performance for all Intel 32-bit and 64-bit processors, while not requiring the need for porting applications from other compilers. It provides optimization technology, threaded application support, and features to take advantage of Hyper-Threading technology. It is substantially source and object code compatible with GNU C, providing fullest compatibility with GCC and G++ 3.x/4.x both in terms of code and of API. It is thereby also easy to integrate with existing development environments. License: Other/Proprietary License with Free Trial Changes:
Support for the Intel® Atom™ Processor line was added. C++ Lambda functions are now supported. OpenMP support was updated to 3.0. Decimal floating point according to the IEEE 754R standard was implemented. Parallel compilation was improved. Many other improvements were made. Image

C Compiler for Solaris 8 (Intel)

hi I'm looking for a C Compiler that will run on a Solaris 8 (Intel) platform and that doesn't need to be complied. I've tried gcc binaries but they don't seem to work. Thanx. (5 Replies)

cpu_capabilities

cpu_capabilities(3alleg4)					  Allegro manual					 cpu_capabilities(3alleg4)

NAME

       cpu_capabilities - Contains the capability flags of the CPU. Allegro game programming library.

SYNOPSIS

       #include <allegro.h>

       extern int cpu_capabilities;

DESCRIPTION

       Contains CPU flags indicating what features are available on the current CPU. The flags can be any combination of these:

	  CPU_ID       - Indicates that the "cpuid" instruction is
			 available. If this is set, then all Allegro CPU
			 variables are 100% reliable, otherwise there
			 may be some mistakes.
	  CPU_FPU      - An FPU is available.
	  CPU_IA64     - Running on Intel 64 bit CPU
	  CPU_AMD64    - Running on AMD 64 bit CPU
	  CPU_MMX      - Intel MMX  instruction set is available.
	  CPU_MMXPLUS  - Intel MMX+ instruction set is available.
	  CPU_SSE      - Intel SSE  instruction set is available.
	  CPU_SSE2     - Intel SSE2 instruction set is available.
	  CPU_SSE3     - Intel SSE3 instruction set is available.
	  CPU_3DNOW    - AMD 3DNow! instruction set is available.
	  CPU_ENH3DNOW - AMD Enhanced 3DNow! instruction set is
			 available.
	  CPU_CMOV     - Pentium Pro "cmov" instruction is available.

       You  can check for multiple features by OR-ing the flags together.  For example, to check if the CPU has an FPU and MMX instructions avail-
       able, you'd do:

	  if ((cpu_capabilities & (CPU_FPU | CPU_MMX)) ==
	      (CPU_FPU | CPU_MMX)) {
	     printf("CPU has both an FPU and MMX instructions!
");
	  }

       You can read this variable after you have called check_cpu() (which is automatically called by allegro_init()).
