AMD Alleges Intel Compilers Create Slower AMD Code
edxwelch writes "In AMD's recient anti-trust
lawsuit
AMD have examined the Intel compiler and found that it deliberatly runs code slower when it detects that the processor is an AMD.
"To achieve this, Intel designed the compiler to compile code
along several alternate code paths. ... By design, the
code paths were not created equally. If the program detects a "Genuine Intel" microprocessor,
it executes a fully optimized code path and operates with the maximum efficiency. However,
if the program detects an "Authentic AMD" microprocessor, it executes a different code path
that will degrade the program's performance or cause it to crash.""
This was listed in the anti-trust lawsuit and discussed already.
so what if intel compiliers do that? it's the INTEL compilier. first of all, of course code compiled on the INTEL compilier is going to run fastest on intel chips b/c intel knows the inner workings of their chips better than they'd know AMDs. why spend all the money for R&D to learn AMDs chips to make a free compiler who's sole purpose in life is speed up processes on intel chips.
nobody is stopping AMD from making a free compiler that does the same thing.
STFU AMD, and ante up.
Isn't it possible they just know their own product better and thus can create a better compiler for it?
Technology, the cause of and solution to all of life's problems.
Another example of AMD trying to win in the marketplace through whining. There is nothing preventing AMD from releasing their own compiler. Instead they are just bitching about Intel again.
Intel doesn't come close to a monopoly in the compiler market, so I fail to see what this has to do with the antitrust suit.

Wow, what color is the sky in your world? You live in a Red state don't you?
On a related note, is there any way by which the authors of the GNU compiler collection (GCC) would limit the range of x86 instructions generated by GCC compilers? Some instructions are simply too complex and could actually be replaced by sequences of simpler instructions, and each such sequence would actually run faster than the original, more complex instruction. A simplified subset of the x86 instructions is sufficient for compiling all computer programs.
By restricting the GCC compilers to generating only a simple but fast subset of instructions, we could encourage both AMD and Intel to deprecate and, ultimately, eliminate the more complex x86 instructions. Linux and the bulk of open-source software use the GCC compilers and would provide a critical mass of support for a new streamlined transistor-count-reduced x86 chips. Here, I am thinking, "shockingly reduced in power due to using 1/3 of the transistors."
Quit being so god damn picky, so it was in AAC not MP3 the point is still valid and accurate nitpicky dumbass moron. Yes flamebait was intentional and it was deserved for the sheer stupidity.

Beware: In C++, your friends can see your privates!
Yes, Intel should spend its R&D budget developing an optimized compiler for AMD.
I'm glad we have a bunch of liberal socialists supporting AMD.
Excuse me while I go listen to Rush's "The Trees" and read some Ayn Rand.

"During my senior year of undergrad my computer architecture professor consistently refered to Intel as "the evil empire", so who knows."
Well, that cinches it! If your professor and classmates referred to Intel as the evil empire, it MUST be true!
By that kind of reasoning Hitler was right.
Where did you learn to think, the back of a cereal box?
My God! I mean, you have to use a compiler switch to generate optimized code?! Outrageous! P-o-s-i-t-i-v-e-l-y o-u-t-r-a-g-e-o-u-s!!! I mean, all these years I used GCC and I never had to use any switches to generate the fastest code possible. We're suing the bastards!!
