[AArch64] Simplify frame pointer logic
Simplify frame pointer logic. Add aarch64_needs_frame_chain to
decide when to emit the frame chain using clearer logic.
Introduce aarch64_use_frame_pointer which contains the value of
-fno-omit-frame-pointer (flag_omit_frame_pointer is set to a magic
value so that the mid-end won't force the frame pointer in all
cases, and leaf frame pointer emission can't be supported).
gcc/
* config/aarch64/aarch64.c (aarch64_use_frame_pointer):
Add new boolean.
(aarch64_needs_frame_chain): New function.
(aarch64_parse_override_string): Set aarch64_use_frame_pointer.
