[Bug c/14128] New: internal compiler error: asm clobber conflict with output operand

[ilja dot honkonen at helsinki dot fi]

I was compiling jpeg-mmx-1.1.2 for mjpegtools and got this:
[root@localhost jpeg-mmx]# ./configure --enable-shared && make
...
./libtool --mode=compile gcc -O6  -I. -c ./jfdctflt.c
gcc -O6 -I. -c -fPIC -DPIC ./jfdctflt.c
mv -f jfdctflt.o jfdctflt.lo
./libtool --mode=compile gcc -O6  -I. -c ./jfdctint.c
gcc -O6 -I. -c -fPIC -DPIC ./jfdctint.c
mv -f jfdctint.o jfdctint.lo
./libtool --mode=compile gcc -O6  -I. -c ./jdapimin.c
gcc -O6 -I. -c -fPIC -DPIC ./jdapimin.c
jdapimin.c: In function `mmxsupport':
jdapimin.c:463: internal compiler error: asm clobber conflict with output

Please submit a full bug report,
with preprocessed source if appropriate.
See <URL:http://gcc.gnu.org/bugs.html> for instructions.

Following the instructions I got to this:

I've made a jdapimin.i.bz2 but don't know how to attach it here so I've put it

This is because the asm clobbers the PIC register. I think we have a better
diagnostic for this on mainline, but I don't have an i386 to check.
