sdesmalen edited the summary of this revision.
sdesmalen added a comment.

- Changed condition to `useFPForScavengingIndex`
- Added new test `framelayout-scavengingslot.mir` to guard that stack realignment (without SVE) allocates the scavenging slot in the right place.
- Simplified patch, no need to refactor `estimateSVEStackObjectOffsets`
- Renamed misleading/wrong title of this patch.
