Subject: [PATCH] aarch64: Minor initial adjustment tweak
|
|
|
|
This patch just changes a calculation of initial_adjust
|
|
to one that makes it slightly more obvious that the total
|
|
adjustment is frame.frame_size.
|
|
|
|
gcc/
|
|
* config/aarch64/aarch64.c (aarch64_layout_frame): Tweak
|
|
calculation of initial_adjust for frames in which all saves
|
|
are SVE saves.
