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.

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.
