Bug ID: 34873
Summary: [X86] Execution domain fixing should be able to turn
PBLENDW into BLENDPS/BLENDPD
Product: libraries
Version: trunk
Hardware: PC
OS: All
Status: NEW
Severity: enhancement
Priority: P
Component: Backend: X86
Assignee: [email protected]

With SSE41 the only integer domain blend that uses an immediate is BLENDW which
has 16-bit elements. Ideally, execution domain fixing should be able to convert
it to floating point when the element size is really at least 32-bits, but that
requires rewriting the immediate. This is more than what the simple table based
domain fixing can currently do.
