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. - -gcc/ - * 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. ---- - gcc/config/aarch64/aarch64.cc | 6 +++--- - gcc/config/aarch64/aarch64.h | 6 +++--- - 2 files changed, 6 insertions(+), 6 deletions(-) - -diff --git a/gcc/config/aarch64/aarch64.cc b/gcc/config/aarch64/aarch64.cc -index 0e9b9717c085..0a22f91520e5 100644 ---- a/gcc/config/aarch64/aarch64.cc -+++ b/gcc/config/aarch64/aarch64.cc -@@ -8598,7 +8598,7 @@ aarch64_layout_frame (void) - STACK_BOUNDARY / BITS_PER_UNIT)); - frame.frame_size = saved_regs_and_above + frame.bytes_below_saved_regs; - -- frame.locals_offset = frame.saved_varargs_size; -+ frame.bytes_above_locals = frame.saved_varargs_size; - - frame.initial_adjust = 0; - frame.final_adjust = 0; -@@ -12754,13 +12754,13 @@ aarch64_initial_elimination_offset (unsigned from, unsigned to) - return frame.hard_fp_offset; - - if (from == FRAME_POINTER_REGNUM) -- return frame.hard_fp_offset - frame.locals_offset; -+ return frame.hard_fp_offset - frame.bytes_above_locals; - } - - if (to == STACK_POINTER_REGNUM) - { - if (from == FRAME_POINTER_REGNUM) -- return frame.frame_size - frame.locals_offset; -+ return frame.frame_size - frame.bytes_above_locals; - } - - return frame.frame_size; -diff --git a/gcc/config/aarch64/aarch64.h b/gcc/config/aarch64/aarch64.h -index fd820b1be4eb..7ae12d13e2b4 100644 ---- a/gcc/config/aarch64/aarch64.h -+++ b/gcc/config/aarch64/aarch64.h -@@ -791,10 +791,10 @@ struct GTY (()) aarch64_frame - always a multiple of STACK_BOUNDARY. */ - poly_int64 bytes_below_hard_fp; - -- /* Offset from the base of the frame (incomming SP) to the -- top of the locals area.
