[Jay Foad via Phabricator via llvm-commits]

foad added inline comments.


================
Comment at: llvm/test/CodeGen/AMDGPU/mul_int24.ll:223
+  %lshr.rhs = shl i64 %rhs, 40
+  %rhs24 = ashr i64 %lhs, 40
+  %mul = mul i64 %lhs24, %rhs24
----------------
"lhs" should be "lshr.rhs" here.


================
Comment at: llvm/test/CodeGen/AMDGPU/mul_int24.ll:286
+  %lshr.rhs = shl <2 x i64> %rhs, <i64 40, i64 40>
+  %rhs24 = ashr <2 x i64> %lhs, <i64 40, i64 40>
+  %mul = mul <2 x i64> %lhs24, %rhs24
----------------
Same.
