From 6151b7b5b05debc85d8df044951b0893c43a4e0b Mon Sep 17 00:00:00 2001 From: aoliva Date: Wed, 19 Aug 2015 17:00:32 +0000 Subject: [PR64164] fix regressions reported on m68k and armeb Defer stack slot address assignment for all parms that can't live in pseudos, and accept pseudos assignments in assign_param_setup_block. for gcc/ChangeLog PR rtl-optimization/64164 * cfgexpand.c (parm_maybe_byref_p): Renamed to... (parm_in_stack_slot_p): ... this. Disregard mode, what matters is whether the parm will live in a pseudo or a stack slot. (expand_one_ssa_partition): Deal with params without a default def. Disregard mode. * cfgexpand.h: Renamed function declaration. * tree-ssa-coalesce.c: Adjust. * function.c (split_complex_args): Allocate stack slot for unassigned parms before splitting. (parm_in_unassigned_mem_p): New. Use it instead of parm_maybe_byref_p throughout this file. (assign_parm_setup_block): Use it. Accept pseudos in the expand-assigned rtl. (assign_parm_setup_reg): Drop BLKmode requirement. (assign_parm_setup_stack): Allocate and fill in the address of unassigned MEM parms. git-svn-id: svn+ssh://gcc.gnu.org/svn/gcc/trunk@227015 138bc75d-0d04-0410-961f-82ee72b054a4 --- gcc/cfgexpand.h | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'gcc/cfgexpand.h') diff --git a/gcc/cfgexpand.h b/gcc/cfgexpand.h index 987cf356a40..d1686724083 100644 --- a/gcc/cfgexpand.h +++ b/gcc/cfgexpand.h @@ -22,7 +22,7 @@ along with GCC; see the file COPYING3.
