Options

rs6000.c (rs6000_emit_stack_reset): Return generated insn if it is changing sp. 

	* config/rs6000/rs6000.c (rs6000_emit_stack_reset): Return generated
	insn if it is changing sp.  Use gen_add3_insn instead of
	conditionally gen_addsi3 and gen_adddi3.
	(offset_below_red_zone_p): New static inline function.
	(rs6000_emit_epilogue): Emit needed epilogue unwind info.
	Use gen_add3_insn instead of conditionally gen_addsi3 and gen_adddi3.
	* config/rs6000/ppc-asm.h: Include auto-host.h.
	(CFI_STARTPROC, CFI_ENDPROC, CFI_DEF_CFA_REGISTER, CFI_OFFSET,
	CFI_RESTORE): Define.
	* config/rs6000/crtresxgpr.asm: Add unwind info.
	* config/rs6000/crtresxfpr.asm: Likewise.
