[Bug target/13041] New: linux-2.6/sound/core/oss/rate.c miscompiled

["debian-gcc at lists dot debian dot org" <gcc-bugzilla at gcc dot gnu dot org>]

[ forwarded from http://bugs.debian.org/219949 ]

gcc-3.3.2 release:

gcc -march=i386 -fomit-frame-pointer -O2

miscompiles sound/core/oss/rate.c in Linux 2.6.0-test9.

I've attached the preprocessed source that demonstrates the
problem.

In the assembly output with -S, look for the 5th label in
get_s16_labels.0.  That label should do a word load, but
instead it does a double word load:

.L4:
        movl    (%ebp), %eax
        jmp     .L111
