* tree-eh.c (tree_remove_unreachable_handlers): Handle shared labels. (tree_empty_eh_handler_p): Allow non-EH predecestors; allow region to be reached by different label than left. (update_eh_edges): Update comment; remove edge_to_remove if possible and return true if suceeded. (cleanup_empty_eh): Accept sharing map; handle shared regions. (cleanup_eh): Compute sharing map. * except.c (remove_eh_handler_and_replace): Add argument if we should update regions. (remove_unreachable_regions): Update for label sharing. (label_to_region_map): Likewise. (get_next_region_sharing_label): New function. (remove_eh_handler_and_replace): Add update_catch_try parameter; update prev_try pointers. (remove_eh_handler): Update. (remove_eh_region_and_replace_by_outer_of): New function. * except.h (struct eh_region): Add next_region_sharing_label. (remove_eh_region_and_replace_by_outer_of, get_next_region_sharing_label): Declare. * tree-cfgcleanup.c (tree_forwarder_block_p): Simplify. * tree-cfg.c (split_critical_edges): Split also edges where we can't insert code even if they are not critical. * tree-cfg.c (gimple_can_merge_blocks_p): EH edges are unmergable. (gimple_can_remove_branch_p): EH edges won't remove branch by redirection. * tree-inline.c (update_ssa_across_abnormal_edges): Do handle updating of non-abnormal EH edges. * tree-cfg.c (gimple_can_merge_blocks_p): EH edges are unmergable. (gimple_can_remove_branch_p): EH edges are unremovable by redirection. (split_critical_edges): Split also edges where emitting code on them will lead to splitting later. From-SVN: r146763 |

This directory contains the GNU Compiler Collection (GCC). The GNU Compiler Collection is free software. See the file COPYING for copying permission. The manuals, and some of the runtime libraries, are under different terms; see the individual source files for details. The directory INSTALL contains copies of the installation information as HTML and plain text. The source of this information is gcc/doc/install.texi. The installation information includes details of what is included in the GCC sources and what files GCC installs. See the file gcc/doc/gcc.texi (together with other files that it includes) for usage and porting information. An online readable version of the manual is in the files gcc/doc/gcc.info*. See http://gcc.gnu.org/bugs.html for how to report bugs usefully.
