[RFC][AArch64] Homogeneous Prolog and Epilog for Size Optimization
....
*Homogeneous Prolog and Epilog for Size Optimization, D76570
<https://reviews.llvm.org/D76570>:*
Prolog and epilog to handle callee-save registers tend to be irregular with
different immediate offsets, which are not often being outlined (by machine
outliner) when optimizing for size. From D18619, combining stack operations
stretched irregularity further.
This patch tries to emit homogeneous stores and loads with the same offset
for prolog and epilog respectively. We have observed that this homogeneous
prolog and epilog significantly increased the chance of outlining,
resulting in a code s...
