Man tweaks Intel compiler to speed up Athlon FX51

THERE'S AN INTERESTING filing at the COMP.ARCH Usenet group which describes an experiment with an Intel compiler.

The person who posted the message said that he managed to tweak Intel's compiler to optimise an AMD FX51.

It took him a little bit of disassembly of the Intel-specific binary to get there, but once he'd disposed of a flag specific to its chips, he claimed that he ran a binary and got a 22% performance boost on the program.
