Hello,
to be able to reproduce this problem, we need a _complete_ testcase, ie code that will compile
directly. Also you don't specify what options beside -march=pentium4 you use. Could you please
attach a self-contained testcase, and describe what, if any, other gcc options you used to compile
this? Note that if you didn't use any options besides -march=pentium4, you are getting
_extremely_ unoptimized code. Thanks,
Dara
