Subject: [ConstantFolding] Fold undef for integer intrinsics
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=01f4bc2efa85d9ccd84d5b355597d861603fac82;p=llvm

[ConstantFolding] Fold undef for integer intrinsics

This fixes https://bugs.llvm.org/show_bug.cgi?id=40110.

This implements handling of undef operands for integer intrinsics in
ConstantFolding, in particular for the bitcounting intrinsics (ctpop,
cttz, ctlz), the with.overflow intrinsics, the saturating math
intrinsics and the funnel shift intrinsics.

The undef behavior follows what InstSimplify does for the general cas
e of non-constant operands. For the bitcount intrinsics (where
InstSimplify doesn't do undef handling -- there cannot be a combination
of an undef + non-constant operand) I'm using a 0 result if the intrinsic
is defined for zero and undef otherwise.
