Bug ID: 17744
Summary: SLP Vectorizer: need to support loop-aware cost model
Product: libraries
Version: trunk
Hardware: PC
OS: All
Status: NEW
Severity: normal
Priority: P
Component: Loop Optimizer
Assignee: [email protected]
Reporter: [email protected]
CC: [email protected]
Classification: Unclassified
We vectorize code in multiple basic blocks. Some of the basic blocks are
inside loops. This means that some code is executed more frequently and the
cost model should take this into account.
