- Subject: [patch committed SH] Add -mieee to *_LIBGCC2_CFLAGS
Hi,
The attached patch adds -mieee to the compiler options used
for libgcc2.c. I've missed that libgcc2.c:__{mul,div}dc3
use nan&inf which require -mieee on SH. Although the third
hunk is currently redundant, I add it as a fool proof.
The patch is tested for sh-elf and sh4-unknown-linux-gnu.
Committed.
Regards,
kaz
