Author: jakub Date: Tue Oct 7 18:48:40 2008 New Revision: 140948 URL: http://gcc.gnu.org/viewcvs?root=gcc&view=rev&rev=140948 Log: PR debug/29609 PR debug/36690 PR debug/37616 * basic-block.h (struct edge_def): Add goto_block field. * cfglayout.c (fixup_reorder_chain): Ensure that there is at least one insn with locus corresponding to edge's goto_locus if !optimize. * profile.c (branch_prob): Copy edge's goto_block. * cfgrtl.c (force_nonfallthru_and_redirect): Use goto_locus for emitted jumps. (cfg_layout_merge_blocks): Emit a nop with edge's goto_locus locator in between the merged basic blocks if !optimize and needed. * cfgexpand.c (expand_gimple_cond): Convert goto_block and goto_locus into RTL locator. For unconditional jump use that locator for the jump insn. (expand_gimple_cond): Convert goto_block and goto_locus into RTL locator for all remaining edges. For unconditional jump use that locator for the jump insn. * cfgcleanup.c (try_forward_edges): Avoid the optimization if there is more than one edge or insn locator along the forwarding edges and !optimize. If there is just one, set e->goto_locus. * tree-cfg.c (make_cond_expr_edges, make_goto_expr_edges): Set also edge's goto_block. (move_block_to_fn): Adjust edge's goto_block. * gcc.dg/debug/pr29609-1.c: New test. * gcc.dg/debug/pr29609-2.c: New test. * gcc.dg/debug/pr36690-1.c: New test. * gcc.dg/debug/pr36690-2.c: New test. * gcc.dg/debug/pr36690-3.c: New test. * gcc.dg/debug/pr37616.c: New test. * gcc.dg/debug/dwarf2/pr29609-1.c: New test. * gcc.dg/debug/dwarf2/pr29609-2.c: New test. * gcc.dg/debug/dwarf2/pr36690-1.c: New test. * gcc.dg/debug/dwarf2/pr36690-2.c: New test. * gcc.dg/debug/dwarf2/pr36690-3.c: New test. * gcc.dg/debug/dwarf2/pr37616.c: New test.
