Sanjay Patel 46f44cd641 [InstSimplify] fold nested min/max intrinsics with constant operands ... This is based on the existing code for the non-intrinsic idioms in InstCombine. The vector constant constraint is non-obvious: undefs should be ok in the outer call, but they can't propagate safely from the inner call in all cases. Example: https://alive2.llvm.org/ce/z/-2bVbM define <2 x i8> @src(<2 x i8> %x) { %0: %m = umin <2 x i8> %x, { 7, undef } %m2 = umin <2 x i8> { 9, 9 }, %m ret <2 x i8> %m2 } => define <2 x i8> @tgt(<2 x i8> %x) { %0: %m = umin <2 x i8> %x, { 7, undef } ret <2 x i8> %m } Transformation doesn't verify! ERROR: Value mismatch Example: <2 x i8> %x = < undef, undef > Source: <2 x i8> %m = < #x00 (0) [based on undef value], #x00 (0) > <2 x i8> %m2 = < #x00 (0), #x00 (0) > Target: <2 x i8> %m = < #x07 (7), #x10 (16) > Source value: < #x00 (0), #x00 (0) > Target value: < #x07 (7), #x10 (16) >		2020-08-04 08:44:48 -04:00
