Author: jakub Date: Fri Oct 12 07:10:22 2007 New Revision: 129254 URL: http://gcc.gnu.org/viewcvs?root=gcc&view=rev&rev=129254 Log: PR tree-optimization/33645 * tree-ssa-live.c (mark_all_vars_used): Add data argument, pass it to walk_tree. (mark_all_vars_used_1): Pass data through to mark_all_vars_used. When calling set_is_used on a VAR_DECL, if data is not NULL and its DECL_UID is in the bitmap, call mark_all_vars_used on its DECL_INITIAL after clearing the bit in bitmap. (remove_unused_locals): Adjust mark_all_vars_used callers. Instead of removing unused global vars from unexpanded_var_list immediately record them in bitmap, call mark_all_vars_used on all used global vars from unexpanded_var_list and only purge global vars that weren't found used even during that step. * gcc.dg/pr33645-1.c: New test. * gcc.dg/pr33645-2.c: New test. * gcc.dg/pr33645-3.c: New test.
