Subject: [SPARC] Minor tweaks
Date: Sat, 23 Mar 2013 12:31:17 +0100

The correct test for the pointer size in sparc_emit_probe_stack_range is 
TARGET_ARCH64 instead of TARGET_64BIT.  The patch also adds predicates to the 
3rd argument of ctrapsi4 and ctrapdi4.

Tested on SPARC/Solaris, applied on the mainline.

	* config/sparc/sparc.c (sparc_emit_probe_stack_range): Fix small
	inaccuracy in the probing code.

	* config/sparc/sparc.md (ctrapsi4): Add predicate for operand #3.
	(ctrapdi4): Likewise.
