Perhaps. Anyway looks fine to me except one minor failure
on sh64-elf:
xsh64-elf-combined/combined/libgcc/libgcc2.c: In function '__powisf2':
xsh64-elf-combined/combined/libgcc/libgcc2.c:1779:1: error: unrecognizable
insn:
(insn 11 10 12 3 (set (reg:DI 170)
(abs:DI (reg:DI 169)))
xsh64-elf-combined/combined/libgcc/libgcc2.c:1770 -1
(nil))
xsh64-elf-combined/combined/libgcc/libgcc2.c:1779:1: internal compiler error:
in extract_insn, at recog.c:2123
The failure went away if restricting new absdi2 expander to TARGET_SH1.
