(In reply to Maciej W. Rozycki from comment #13)
This breaks Power SPE targets, at least the Linux OS, almost surely EABI
too. Seen in 4.8 powerpc-linux-gnu g++ and libstdc++

--- Comment #15 from Maciej W. Rozycki ma...@linux-mips.org ---
There is no ICE, this is target code in libgcc_s.so.1 calling abort at
run time whenever the DWARF2 unwinder is called. Shall I send you
binaries?
NB SPE GPRs indeed are 64-bit wide

FWIW, I was able to bootstrap subversion id 202295 on my x86_68 laptop
running RHEL 6.4, building c, c++, fortran languages, and using
--enable-lto --without-ppl

Reading the comments above and pr58269, does this mean my patch just exposed a
latent bug? ...and the supplied patches fix the latent bug?

Boostrap with obj* completed successfully with r202295 reverted. I start again
with the patch in comment#9.

This looks like a scheduling bug. Just before sched2, we have:
(call_insn 29 28 31 2 (parallel [
(set (reg:DF 33 1)
(call (mem:SI (symbol_ref:DI (log)
16 matches
