8 years agoThis patch optimizes the prolog and epilog code to reduce the number of instructions...
Wilco Dijkstra [Mon, 1 Aug 2016 16:37:24 +0000 (16:37 +0000)]
This patch optimizes the prolog and epilog code to reduce the number of instructions and avoid multiple writes to SP.

This patch optimizes the prolog and epilog code to reduce the number of
instructions and avoid multiple writes to SP.  The key idea is that epilogs
are almost exact reverses of prologs, and thus all the decisions only need
to be taken once.  The frame layout is decided in aarch64_layout_frame()
and decisions recorded in the new aarch64_frame fields initial_adjust,
callee_adjust, callee_offset and final_adjust.

A generic frame setup consists of 5 basic steps:

1. sub sp, sp, initial_adjust
2. stp reg1, reg2, [sp, -callee_adjust]!      (push if callee_adjust != 0)
3. add fp, sp, callee_offset                  (if frame_pointer_needed)
4. stp reg3, reg4, [sp, callee_offset + N*16] (store remaining callee-saves)
5. sub sp, sp, final_adjust

The epilog reverses this, and may omit step 3 if alloca wasn't used.

    gcc/
* config/aarch64/aarch64.h (aarch64_frame):
