[SCCP] Use constant ranges for casts.

[fhahn]

Summary

For casts with constant range operands, we can use
ConstantRange::castOp.

Only cast between integer types with constant ranges.

[jdoerfert]

I am somehow missing the extra folding in the test case. What is folded now?

Nothing, the test make sure we skip int -> fp casts, rather than crash :)

Gotcha.

[fhahn]

Ping. I think all required patches should have landed over the last week or so.

Rebased.

[fhahn]

ping :)

This is calling both markConstant and mergeInValue?

818

If I'm following correctly, both the source and destination must be integers, so this is one of bitcast/trunc/sext/zext?

[fhahn]

Thanks Eli!

Removed the unnecessary mergeIn.

llvm/lib/Transforms/Scalar/SCCP.cpp

816

This could just be markConstant as it was originally I think. Not sure if there are any scenarios where we would get constant after already having a (non-singleton) range.

818

Yep, otherwise we would mark the result of %tmp4 = sitofp i32 %r to double as constant range, if %r is a constant range.

LGTM
