Linux 2.4.19rc1
Intel P4 2GHz on Asus P4T533-C
CFLAGS=CXXFLAGS="-march=pentium4 -O3 -pipe"
glibc-2.2.5
>Description:
Trying to compile XFree86-4.2.0 with
CFLAGS="-march=pentium4 -O3 -pipe" have the effect as
attatched in xfree.log.
>How-To-Repeat:
This happens every time.
>Fix:
Recompiling just miFont.c with
CFLAGS="-march=pentium3 -O3 -pipe" fixes this problem.
It seems thus that it is a problem with the pentium4
