[PATCH] D68996: [AArch64][SVE] Spilling/filling of SVE callee-saves.

[Sander de Smalen via Phabricator via llvm-commits]

sdesmalen updated this revision to Diff 227272.
sdesmalen added a comment.

- Removed changes to `convertCalleeSaveRestoreToSPPrePostIncDec` as they were wrong and are no longer necessary.
- Fixed a possible issue in `IsSVECalleeSave`, by now checking for FrameSetup/FrameDestroy flags, instead of relying the address is a frame-index.
- Added a comment to `setSVECalleeSavedStackSize`.
- Added test that spills/fills ZPR callee-saved regs in isolation.
- Added test that spills/fills PPR callee-saved regs in isolation.
- Extended test `save_restore_sve` with some GPR callee-saved spills/fills to test that pairing of GPR regs still works in combination with SVE callee saves.
