--- Comment #13 from Jakub Jelinek <jakub at gcc dot gnu.org> 2011-03-28 23:53:49 UTC --- Author: jakub Date: Mon Mar 28 23:53:46 2011 New Revision: 171640 URL: http://gcc.gnu.org/viewcvs?root=gcc&view=rev&rev=171640 Log: PR debug/48203 * cfgexpand.c (expand_debug_expr) <case SSA_NAME>: Only create ENTRY_VALUE if incoming or address of incoming's MEM is a hard REG. * dwarf2out.c (mem_loc_descriptor): Don't emit DW_OP_GNU_entry_value of DW_OP_fbreg. * var-tracking.c (vt_add_function_parameter): Ensure cselib_lookup on ENTRY_VALUE is able to find the canonical parameter VALUE. * cselib.c (rtx_equal_for_cselib_1) <case ENTRY_VALUE>: Use rtx_equal_p instead of rtx_equal_for_cselib_1 to compare ENTRY_VALUE_EXPs. (cselib_hash_rtx) <case ENTRY_VALUE>: If ENTRY_VALUE_EXP is a REG_P or MEM_P with REG_P address, compute hash directly instead of calling cselib_hash_rtx on ENTRY_VALUE_EXP. (preserve_only_constants): Don't clear VALUES forwaring ENTRY_VALUE to some other VALUE. * gcc.dg/pr48203.c: New test. Added: trunk/gcc/testsuite/gcc.dg/pr48203.c Modified: trunk/gcc/ChangeLog trunk/gcc/cfgexpand.c trunk/gcc/cselib.c trunk/gcc/dwarf2out.c trunk/gcc/testsuite/ChangeLog trunk/gcc/var-tracking.c
