Sanjay Patel 563fa4255c [InstCombine] fold add(zext(xor X, C), C) --> sext X when C is INT_MIN in the source type ... The pattern may look more obviously like a sext if written as: define i32 @g(i16 %x) { %zext = zext i16 %x to i32 %xor = xor i32 %zext, 32768 %add = add i32 %xor, -32768 ret i32 %add } We already have that fold in visitAdd().
