-Subject: [PATCH 21/32] aarch64: Rename locals_offset to bytes_above_locals
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-locals_offset was described as:
-
- /* Offset from the base of the frame (incomming SP) to the
- top of the locals area. This value is always a multiple of
- STACK_BOUNDARY. */
-
-This is implicitly an “upside down” view of the frame: the incoming
-SP is at offset 0, and anything N bytes below the incoming SP is at
-offset N (rather than -N).
-
-However, reg_offset instead uses a “right way up” view; that is,
-it views offsets in address terms. Something above X is at a
-positive offset from X and something below X is at a negative
-offset from X.
-
-Also, even on FRAME_GROWS_DOWNWARD targets like AArch64,
-target-independent code views offsets in address terms too:
-locals are allocated at negative offsets to virtual_stack_vars.
-
-It seems confusing to have *_offset fields of the same structure
-using different polarities like this. This patch tries to avoid
-that by renaming locals_offset to bytes_above_locals.

- * config/aarch64/aarch64.h (aarch64_frame::locals_offset): Rename to...
- (aarch64_frame::bytes_above_locals): ...this.
- * config/aarch64/aarch64.cc (aarch64_layout_frame)
- (aarch64_initial_elimination_offset): Update accordingly.
