    • [RS6000] PR 80938, Don't emit frame info for regs that don't need saving · b263d657 
      It is possible when using out-of-line register saves or store multiple
to save some registers unnecessarily, for example one reg in the block
saved might be unused.  We don't need to emit frame info for those
registers as that just bloats the info, and also can result in an ICE
when shrink-wrap gives multiple paths through the function saving
different sets of registers.  Join points need to have identical frame
register save state regardless of the path taken.

This patch reverts the previous fix for PR80939 "Use SAVE_MULTIPLE
only if we restore what it saves (PR80938)" and instead fixes the PR
by correcting the frame info.  The change to rs6000_savres_strategy
is an optimization, but note that it hides the underlying problem in
the PR testcase.

	PR target/80938
	* config/rs6000/rs6000.c (rs6000_savres_strategy): Revert 2017-08-09.
	Don't use store multiple if only one reg needs saving.
	(interesting_frame_related_regno): New function.
	(rs6000_frame_related): Don't emit frame info for regs that
	don't need saving.
	(rs6000_emit_epilogue): Likewise.

    • Limit SH strncmp inline expansion (PR target/78460). · aaf46c35 
      GCC mainline built for sh4-linux-gnu runs out of memory building a
glibc test, which calls strncmp with very large constant size
argument, resulting in the SH inline strncmp expansion trying to
inline a fully unrolled expansion of strncmp for that size.

This patch limits that fully unrolled expansion to the case of less
than 32 bytes.  This is explicitly *not* trying to be optimal in any
way (very likely a lower threshold makes sense), just to limit enough
to avoid the out-of-memory issue in the glibc testsuite.

I have *not* run the GCC testsuite for SH.  I have verified that this
allows the glibc testsuite to build OK, with both GCC mainline and GCC
7 branch (and that the included test builds quickly with patched GCC,
runs out of memory with unpatched GCC).

	PR target/78460
	PR target/67712
gcc:
	* config/sh/sh-mem.cc (sh_expand_cmpnstr): Only unroll for
	constant count if that count is less than 32.
