I have retested on sparc (sol9), by adding some of the
defines in fenv.h for Solaris 10 to the gnu-c99-math.h
file you created, and the patches you posted, and now
I'm getting an error when I compile that looks like this:
for d in i386-softmmu ppc-softmmu sparc-softmmu x86_64-softmmu; do \
gmake -C $d all || exit 1 ; \
done
gmake[1]: Entering directory
`/export/src/qemu-snapshot-2005-05-04_23-sol/i386-softmmu'
../dyngen -c -o opc.h op.o
dyngen: ret; restore; not found at end of op_fstt_ST0_A0
gmake[1]: *** [opc.h] Error 1
gmake[1]: Leaving directory
`/export/src/qemu-snapshot-2005-05-04_23-sol/i386-softmmu'
gmake: *** [all] Error 1
Ideas?
