Synopsis: GCC 3.2 does not check for CMOV instruction before generating code
State-Changed-From-To: open->closed
State-Changed-By: rth
State-Changed-When: Mon Oct 21 23:55:43 2002
State-Changed-Why:
Defined as "not a bug". When we say i686, we really do mean
"pentiumpro". Checking for cmov is a waste of time; it'd be
faster to not use it than to check.
Use -march=i586 instead.
