New Intel Compiler Released 35

Posted by Hemos on Monday November 25, 2002 @11:59AM from the test-it-out dept.

swsnyder writes "A new toy to play with: new Intel compiler (v7.0) available for download at Intel's site. The Windows version is a time limited eval version, but the Linux version is free for non-commercial use. This version is claimed to be even more GCC-compatible that the last version, though I haven't verified this yet."

even more GCC-compatible that the last version

shouldn't it be more standards compliant

  Nope, being more compatible with gcc implies it supports more gcc extensions. That's one reason why the Linux kernel used to break so much between gcc versions, as gcc is chock full of neat and not so neat extensions to the C language.

      Yes. they did. The nifty thing is that they actually list exactly what extensions, in their documentation, and if you don't mind YOUR compiler going under GPL, you can actually just use their code, all nicely pre-written for you. :-P

Wow. These Intel guys are fast: Three new C++ compilers within 48 hours!
...And the're all binary compatible - at least to each other.

  Having some mod points today, I almost modded this as +1 Funny. But then I realised that I don't get the joke. I assume that there's some good reason(s) to run the intel compiler vs gcc. I would guess that it involves specific optimizations for Intel chip(set)s. Am I wrong? Is there more(or less) to it than that? Not being a proffessional programmer, I don't really know.

    Yeah, that's about it. GCC continues to produce mediocre code for the P4 and Itanium. (The latter's very significant - some reports of 50% slower.) There are efforts to fix this but Intel has a significant lead.
    
    The other advantage is vectorization - Intel's compiler makes much better use of MMX/SSE/SSE2 than GCC does. I don't know how ICC compares to VectorC [codeplay.com] but I'd guess they'd have the edge back by now.

  The Intel compiler is a fscking great piece of code. My video compression stuff drops out 20% faster than it does under GCC 3.1. On an AMD chip, and it has specific flags to compile for P4 so god alone knows how fast that would be. All this is before we start to take advantage of the built in vectorisation (that actually sucks a fair bit), or change my source in any way.
  
  Something that's fun, for the geeks out there (what am I doing, this is slashdot) is to turn the optimisation up to full whack but leave the debug symbols in .... Jeez, it does some clever shit.

Is Intel ICC 7.0 ABI compatible with GCC 3.2 ABI? (Score:2)

by truth_revealed ( 593493 ) writes:

The GCC 3.2 C++ compiler is known to have some ABI conformance issues that prevent it from claiming 100% IA32 ABI compability. So the question is: does ICC 7.0 match GCC 3.2's C++ ABI exactly (bug for bug) or does it match the offical IA32 C++ ABI standard (thus rendering it incompatible with GCC 3.2)?

  I would think that it would match GCC bug for bug, if it didnt match those "Features" one for one, then it wouldnt be 100% compatible. Besides, if they wanted to make it 100% IA32 ABI compatible, they would have just written the compiler that way and say its more standards complient then GCC.
