Bug ID: 23481
Summary: MISched: Tail call argument dependency handling very
conservative
Product: libraries
Version: trunk
Hardware: PC
OS: All
Status: NEW
Severity: normal
Priority: P
Component: Common Code Generator Code
Assignee: [email protected]
Reporter: [email protected]
CC: [email protected]
Classification: Unclassified
In PR23459 I fixed a bug in how we handle tail call arguments during building
the dependence graph for scheduling.
This fix essentially made every incoming and outgoing argument stack slot
dependent. We should add an analysis that analyses the actual stack slots for
overlap.
