------- Comment #2 from rguenth at gcc dot gnu dot org 2006-10-23 11:29 ------- Fails on the 4.2.0 branch. On the 4.1 branch it might be due to packports of
2006-05-23 Alexandre Oliva <[EMAIL PROTECTED]> * simplify-rtx.c (simplify_subreg): Adjust REG_OFFSET for big-endian paradoxical subregs. * var-tracking.c (struct micro_operation_def): Document that, for modify micro operations, insn is the subsequent instruction. (var_reg_delete_and_set, var_mem_delete_and_set): Split into... (var_reg_set, var_mem_set): ... new functions. (add_stores): Record subsequent insn. (compute_bb_dataflow): Use new functions for MO_USE. (emit_notes_in_bb): Use new functions for MO_USE. Emit use notes after the insn, and modify notes before the insn known to be the subsequent one. (vt_initialize): Invert sorting of MO_CLOBBERs and MO_SETs. from Alexandre Oliva <[EMAIL PROTECTED]> * var-tracking.c (enum micro_operation_type): Add MO_COPY. (var_debug_decl): New function. (var_reg_set): Follow debug decl link. Add location even if reg is already known to hold some other variable. (var_mem_set): Follow debug decl link. (var_reg_delete_and_set, var_mem_delete_and_set): Follow debug decl link. Delete other known locations of the variable part if requested. (var_reg_delete, var_mem_delete): Delete other known locations of the variable part if requested. (same_variable_part_p): New function. (add_stores): Select MO_COPY when appropriate. (vt_initialize): Handle it. (compute_bb_dataflow, emit_notes_in_bb): Likewise. Delete known locations for MO_SET and MO_CLOBBER. (find_variable_location_part): New function. (set_variable_part, delete_variable_part): Use it. (clobber_variable_part): New function. * dwarf2out.c (dwarf2out_var_location): Do not follow debug decl link. 2006-09-11 Alexandre Oliva <[EMAIL PROTECTED]> PR target/28672 * var-tracking.c (dump_dataflow_set): Start dumping at register zero. (clobber_variable_part): Kill only the variable part in registers holding it, leaving other variables alone. -- rguenth at gcc dot gnu dot org changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |aoliva at gcc dot gnu dot | |org Known to fail| |4.2.0 http://gcc.gnu.org/bugzilla/show_bug.cgi?id=29558
