A reghunt revealed that this patch
2011-11-09 Alan Modra <amodra@gmail.com>
* function.c (bb_active_p): Delete.
(dup_block_and_redirect, active_insn_between): New functions.
(convert_jumps_to_returns, emit_return_for_exit): New functions,
split out from..
(thread_prologue_and_epilogue_insns): ..here. Delete
shadowing variables. Don't do prologue register clobber tests
when shrink wrapping already failed. Delete all last_bb_active
code. Instead compute tail block candidates for duplicating
exit path. Remove these from antic set. Duplicate tails when
reached from both blocks needing a prologue/epilogue and
blocks not needing such.
* ifcvt.c (dead_or_predicable): Test both flag_shrink_wrap and
HAVE_simple_return.
* bb-reorder.c (get_uncond_jump_length): Make global.
* bb-reorder.h (get_uncond_jump_length): Declare.
* cfgrtl.c (rtl_create_basic_block): Comment typo fix.
(rtl_split_edge): Likewise. Warning fix.
(rtl_duplicate_bb): New function.
(rtl_cfg_hooks): Enable can_duplicate_block_p and duplicate_block.
* Makefile.in (function.o): Update dependencies.
is the culprit. Alan, could you please have a look?

Though the behavior is a tiny bit different, this seems to be a dup of bug
51051.
All that's needed is approval of Bernd's patch... and a ChangeLog entry!

That patch is not enough: while it (together with the ones mentioned in
PR 51094, Comment 16) gets me into stage 2 on sparc-sun-solaris2.11, I
still hit the same ICE here:

Works like a charm: an all,ada,obj-c++,go bootstrap on
sparc-sun-solaris2.11 just completed, and there seem to be no
outstanding/unexpected testsuite failures.
Thanks.
