Bug ID: 51876
Summary: Implement ARMIselLowering::hasAndNot
Product: libraries
Version: trunk
Hardware: PC
OS: All
Status: NEW
Severity: enhancement
Priority: P
Component: Backend: ARM
Assignee: [email protected]

I noticed that ARM does not implement the `ARMISelLowering::hasAndNot` function
even though it has the bic / vbic operations[1]. Unfortunately in my tries it's
not as easy as just implementing the function since it leads to changed
patterns for integer saturations which requires updates to codegen matching.
[1] Noticed this in the context of "masked merge" /
