Has anyone got gcc-4.7.0 to build an SH64 kernel without dying?

Has anyone got gcc-4.7.0 to build an SH64 kernel without dying?

[David Howells]

Has anyone had any success building a gcc-4.7.0 that can build SH64 binaries
without dying?  I am seeing ICEs and SEGVs:

include/linux/genhd.h:214:3: internal compiler error: Segmentation fault
mm/madvise.c:285:2: internal compiler error: Segmentation fault
mm/percpu.c: In function 'pcpu_free_area':
mm/percpu.c:602:1: error: unrecognizable insn:
(insn 74 73 75 8 (set (reg:SI 279)
        (abs:SI (reg:SI 280))) mm/percpu.c:575 -1
     (nil))
mm/percpu.c:602:1: internal compiler error: in extract_insn, at recog.c:2123

I'm not entirely certain what target triplet I should be using.  I'm currently
using sh64-linux-gnu.  It does build a compiler (and it can find its
binutils).  I've also tried sh64-elf, but that doesn't work either.

Hmm .. abs:SI ... I'm afraid that was me.  Sorry about that!
Somebody noticed the problem with abs:SI on SH64 a while ago, too.
However, I don't remember whether the fix made it into 4.7.0 or into the
4.7.1 branch.  Could you try with the 4.7.1 branch?
