re PR tree-optimization/33645 (undefined static variable in vortex for -fno-unit-at-a-time)
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.
