Hello,
as far as I understand, when building gcc, I can use --with-arch=pentium
to tell configure that the resulting compiler should emit code optimized
for pentium processors.
But how can I tell the configure script that the compiler itself should
be optimized for a different cpu architecture?
Example #1: Host and build are athlon-xp, target should be pentium.
Example #2: Build is pentium4, Host should be pentium-mmx, target should
be 386.
What configure options should I use? (Host, build and target are all
linux systems, but I think this apply to every system with x86 processor
variants?)
