	PR debug/63284
	* tree-cfgcleanup.c (fixup_noreturn_call): Don't split block
	if there are only debug stmts after the noreturn call, instead
	remove the debug stmts.

	* gcc.dg/pr63284.c: New test.

Fix i386 FP_TRAPPING_EXCEPTIONS.

The i386 sfp-machine.h defines FP_TRAPPING_EXCEPTIONS in a way that is
always wrong: it treats a set bit as indicating the exception is
trapping, when actually a set bit (both for 387 and SSE floating
point) indicates it is masked, and a clear bit indicates it is
trapping.  This patch fixes this bug.

Bootstrapped with no regressions on x86_64-unknown-linux-gnu.

libgcc:
	* config/i386/sfp-machine.h (FP_TRAPPING_EXCEPTIONS): Treat clear
	bits not set bits as indicating trapping exceptions.

gcc/testsuite:
	* gcc.dg/torture/float128-exact-underflow.c: New test.

	Back port from trunk:
	2014-09-19  Michael Meissner  <meissner@linux.vnet.ibm.com>

	* config/rs6000/predicates.md (fusion_gpr_mem_load): Move testing
	for base_reg_operand to be common between LO_SUM and PLUS.
	(fusion_gpr_mem_combo): New predicate to match a fused address
	that combines the addis and memory offset address.

	* config/rs6000/rs6000-protos.h (fusion_gpr_load_p): Change
	calling signature.
	(emit_fusion_gpr_load): Likewise.

	* config/rs6000/rs6000.c (fusion_gpr_load_p): Change calling
	signature to pass each argument separately, rather than
	using an operands array.  Rewrite the insns found by peephole2 to
	be a single insn, rather than hoping the insns will still be
	together when the peephole pass is done.  Drop being called via a
	normal peephole.
	(emit_fusion_gpr_load): Change calling signature to be called from
	the fusion_gpr_load_<mode> insns with a combined memory address
	instead of the peephole pass passing the addis and offset
	separately.

	* config/rs6000/rs6000.md (UNSPEC_FUSION_GPR): New unspec for GPR
	fusion.
	(power8 fusion peephole): Drop support for doing power8 via a
	normal peephole that was created by the peephole2 pass.
	(power8 fusion peephole2): Create a new insn with the fused
	address, so that the fused operation is kept together after
	register allocation is done.
	(fusion_gpr_load_<mode>): Likewise.
