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):
Remove padding0 and hardfp_offset. Add locals_offset,
initial_adjust, callee_adjust, callee_offset and final_adjust.

* config/rs6000/rs6000-protos.h (rs6000_adjust_vec_address): New
function that takes a vector memory address, a hard register, an
element number and a temporary base register, and recreates an
address that points to the appropriate element within the vector.
* config/rs6000/rs6000.c (rs6000_adjust_vec_address): Likewise.

vec_extract with variable element number being a scalar memory

swappable.

storing either element to a memory location, using scratch
registers to pick apart the vector and reconstruct the address.

element number from memory.
