[TER] PR target/48863 : Don't replace expressions across local register variable definitions
PR target/48863
PR inline-asm/70184
* tree-ssa-ter.c (temp_expr_table): Add reg_vars_cnt field.
(new_temp_expr_table): Initialise reg_vars_cnt.
(free_temp_expr_table): Release reg_vars_cnt.
(process_replaceable): Add reg_vars_cnt argument, set reg_vars_cnt
field of TAB.
(find_replaceable_in_bb): Use the above to record register variable
write occurrences and cancel replacement across them.
* gcc.target/arm/pr48863.c: New test.
git-svn-id: svn+ssh://gcc.gnu.org/svn/gcc/trunk@242840 138bc75d-0d04-0410-961f-82ee72b054a4
