[Bug target/40226] New: gcc emits bad opcode 'ffreep' even if march=geode

[cortez8591 at gmail dot com]

I'm using gcc version 4.3.2 (Gentoo 4.3.2-r3 p1.6, pie-10.1.5), in my
/etc/make.conf stays:
CFLAGS="-march=geode -Os -fno-align-jumps -fno-align-functions
-fno-align-labels -fno-align-loops -pipe -fomit-frame-pointer"
CHOST="i586-pc-linux-gnu"
my cpu is AMD Geode LX800 (x86): model name      : Geode(TM) Integrated
Processor by AMD PCS

compiling mplayer brings no problem but when try to run binary, there is SIGILL
at 0x081b6a2b <InitTimer+11>:      ffreep %st(0)

This was different problem, with -march=native.  And according to [1],
-march=geode works OK.  So without the report, as described in comment 1, there
is no way to figure out what is wrong with your gcc.

BTW: This is Gentoo released gcc, so bugs should be reported to Gentoo first.
