Bug ID: 17607
Summary: Improve concat_vector legalization
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
The x86 backend has a DAG combine (PerformConcatCombine() added in r192866) to
better legalize concat_vector when the result vector type is legal, the source
type is illegal and is the result of a bitcast from a legal type. We should
consider generalizing the logic and making this a target-independent part of
standard legalization.
