cfgexpand.c (struct stack_vars_data): Add asan_base and asan_alignb fields.
* cfgexpand.c (struct stack_vars_data): Add asan_base and asan_alignb
fields.
(expand_stack_vars): For -fsanitize=address, use (and set initially)
data->asan_base as base for vars and update asan_alignb.
(expand_used_vars): Initialize data.asan_base and data.asan_alignb.
Pass them to asan_emit_stack_protection.
* asan.c (asan_detect_stack_use_after_return): New variable.
(asan_emit_stack_protection): Add pbase and alignb arguments.
Implement use after return sanitization.
* asan.h (asan_emit_stack_protection): Adjust prototype.
(ASAN_STACK_MAGIC_USE_AFTER_RET, ASAN_STACK_RETIRED_MAGIC): Define.
