--- Comment #9 from Jakub Jelinek <jakub at gcc dot gnu.org> 2012-03-05 20:17:54 UTC --- Author: jakub Date: Mon Mar 5 20:17:44 2012 New Revision: 184958 URL: http://gcc.gnu.org/viewcvs?root=gcc&view=rev&rev=184958 Log: PR debug/51902 * tree.h (BLOCK_SAME_RANGE): Define. * function.c (block_fragments_nreverse): Clear BLOCK_SAME_RANGE if BLOCK_FRAGMENT_CHAIN is non-NULL, but has it cleared. Also clear BLOCK_SAME_RANGE if fragment chain's supercontext fragment isn't equal to supercontext fragment's fragment chain. Adjust BLOCK_SUPERCONTEXT to point to supercontext fragment's fragment origin. (blocks_nreverse_all): Likewise. (reorder_blocks_1): Compute BLOCK_SAME_RANGE bits. Set BLOCK_SUPERCONTEXT to supercontext fragment instead of supercontext fragment's fragment origin. * dwarf2out.c (add_high_low_attributes): If stmt has the same range as its parent (or parents thereof etc.), use the parent's DW_AT_ranges value instead of creating a new .debug_ranges range. Modified: trunk/gcc/ChangeLog trunk/gcc/dwarf2out.c trunk/gcc/function.c trunk/gcc/tree.h
