[Bug target/29230] New: gcc-4.1 generates faulty asm on ARM when compiling openmsx 0.6.1 with -O3

[debian-gcc at lists dot debian dot org]

[forwarded from http://bugs.debian.org/385505]

sorry for the vague report, didn't reproduce that report yet.

gcc-4.1 fails to build openmsx 0.6.1 from source when compiled with -O3.
Experimenting with debian/ARM installed in qemu revealed that 
compiling with -O2 -funswitch-loops -fgcse-after-reload -ffast-math
-funroll-loops works fine.
This seems to point towards the the -finline-functions option.

More detailed concerning this bug can be found in openmsx bugreport
http://bugs.debian.org/385197 .

This doesn't happen with gcc 4.2, nor, apparently, with 4.0.

Yes, 4.0 works, so it's really only a problem in 4.1.
