    • [RS6000] Fix <bd>_<mode> and <bd>tf_<mode> splitters · b43e6340 
      This patch fixes a bug that can result in "insn does not satisfy its
constraints" if these splitters fire due to not getting ctr for the
jump insn.  Since the jump insn can have any of r,m,d,wi,c,l as the
decremented count output, it's not sufficient to check for
gpc_reg_operand (which matches VSX regs for example).  Seen after
correcting register_move_cost when the cost of gpr <-> vsx is much
lower.  Since this is a prerequisite to fixing PR89271, I'm mentioning
that PR in the ChangeLog.

The <bd>tf_<mode> split had a further bug in that it wouldn't match
if the count output was m,d,wi, or l.

	PR target/89271
	* config/rs6000/rs6000.md (<bd>_<mode> split): Check for an int
	output reg on add insn.
	(<bd>tf_<mode> split): Likewise.  Match predicates with insn.

    • Fix excess warnings from -Wtype-limits with location wrappers (PR c++/88680) · 3fe53000 
      PR c++/88680 reports excess warnings from -Wtype-limits after the C++
FE's use of location wrappers was extended in r267272 for cases such as:

  const unsigned n = 8;
  static_assert (n >= 0 && n % 2 == 0, "");

t.C:3:18: warning: comparison of unsigned expression >= 0 is always true
  [-Wtype-limits]
    3 | static_assert (n >= 0 && n % 2 == 0, "");
      |                ~~^~~~

The root cause is that the location wrapper around "n" breaks the
suppression of the warning for the "if OP0 is a constant that is >= 0"
case.

This patch fixes it by calling fold_for_warn on OP0, extracting the
constant.

gcc/c-family/ChangeLog:
	PR c++/88680
	* c-common.c (shorten_compare): Call fold_for_warn on op0 when
	implementing -Wtype-limits.

gcc/testsuite/ChangeLog:
	PR c++/88680
	* g++.dg/wrappers/pr88680.C: New test.
