(RZ_BUFFER_SIZE): New. (struct asan_redzone_buffer): New. (asan_redzone_buffer::emit_redzone_byte): Likewise. (asan_redzone_buffer::flush_redzone_payload): Likewise. (asan_redzone_buffer::flush_if_full): Likewise. (asan_emit_stack_protection): Use asan_redzone_buffer class that is responsible for proper aligned stores and flushing of shadow memory payload. * asan.h (ASAN_MIN_RED_ZONE_SIZE): New. (asan_var_and_redzone_size): Likewise. * cfgexpand.c (expand_stack_vars): Use smaller alignment (ASAN_MIN_RED_ZONE_SIZE) in order to make shadow memory for automatic variables more compact. 2018-11-30 Martin Liska <mli...@suse.cz> PR sanitizer/81715 * c-c++-common/asan/asan-stack-small.c: New test. git-svn-id: svn+ssh://gcc.gnu.org/svn/gcc/trunk@266664 138bc75d-0d04-0410-961f-82ee72b054a4
