- Subject: [RFA] New SH machine types sh4_nofpu, sh4a, sh4a_nofpu and sh4al_dsp
Hi,
the below patch introduces two entirely new SH machine types, sh4a
and sh4al_dsp plus two types which are the base types sh4 and sh4a
with no FPU support (soft-float).
Ok to checkin?

* archures.c (bfd_mach_sh4a, bfd_mach_sh4al_dsp, bfd_mach_sh4_nofpu,
bfd_mach_sh4a_nofpu): New machine types.
* bfd-in2.h: Rebuilt.
* cpu-sh.c (compatible): Remove unused function.
(SH4A_NEXT, SH4AL_DSP_NEXT, SH4_NOFPU_NEXT, SH4A_NOFPU_NEXT): New.
(arch_info_struct): Add sh4a, sh4al_dsp, sh4-nofpu and sh4a-nofpu.
* elf32-sh.c (sh_elf_set_mach_from_flags): Handle them.
