[Bug inline-asm/13818] New: gcc inline assembler compile errors

[jgraham at grahamguitars dot com]

When compiling applications with inline assembly (mostly mmx/sse/3dnow) the
compiler bails out with this error (or close to it): 
can't find a register in class `BREG' while reloading `asm'
attached is the code that gives the error, thoug this example is only polling
the cpu for vender identification.

The command to invoke the error is:
gcc -DHAVE_CONFIG_H -I../.. -I../.. -I../../app -I/usr/include/glib-2.0
-I/usr/lib/glib-2.0/include   -I/usr/local/include cpu-accel.c

attached are all the files needed to reproduce the error.

I cannot reproduce in FSF's 3.3.1, 3.3.2, or 3.5.0 (today).
This looks like a Gentoo bug, please report it to them.
