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.""
Why doesn't AMD release their own compiler? They could easily fork a gcc release and open source it.
The got fined quite a lot of money in Europe...
