...uence of instructions (which I think is lossless)? store i32 %src, i32* %ptr %ptr2 = bitcast i32* %ptr to v2i16* %dst = load v2i16* %ptr2 I am trying to change all vector types (v2i16 and v4i8) in include/llvm/IntrinsicsMips.td to i32, but I can't do that because the code in CodeGenFunction::EmitBuiltinExpr (in clang/CGBuiltin.cpp) raises an assertion when it calls Type::canLoslesslyBitCastTo to check whether conversion between v2i16 (or v4i8) and i32 is legal. To work around this problem, I can put back CodeGenFunction::EmitMipsBuiltinExpr which was removed in r159368 and add code to do type convers...

Type::canLoslesslyBitCastTo(Type *Ty) in lib/VMCore/Type.cpp always returns false when it checks whether an integer can be bitcast to a vector or vice versa. For example, (i32 => v2i16) or (v2i16 => i32) is false. But it seems that it returns true if it is checking conversion between two vector types which have the same size. For example, (v4i8 => v2i16) would return true. What is the
