rs6000.c (rs6000_emit_prologue): Do not place a RTX_FRAME_RELATED_P marker on the UNSPEC_MOVESI_FROM_CR insn.
ChangeLog:
2013-11-14 Ulrich Weigand <Ulrich.Weigand@de.ibm.com>
* config/rs6000/rs6000.c (rs6000_emit_prologue): Do not place a
RTX_FRAME_RELATED_P marker on the UNSPEC_MOVESI_FROM_CR insn.
Instead, add USEs of all modified call-saved CR fields to the
insn storing the result to the stack slot, and provide an
appropriate REG_FRAME_RELATED_EXPR for that insn.
* config/rs6000/rs6000.md ("*crsave"): New insn pattern.
* config/rs6000/predicates.md ("crsave_operation"): New predicate.
testsuite/ChangeLog:
2013-11-14 Ulrich Weigand <Ulrich.Weigand@de.ibm.com>
* g++.dg/eh/ppc64-sighandle-cr.C: New test.
