Subject: [PATCH 26/32] 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.cc (aarch64_layout_frame): Tweak
calculation of initial_adjust for frames in which all saves
are SVE saves.
