+TEST_CASE("InterpStringZeroCost")
- * INTERP CODE REVIEW: This test fails, but its not clear to me why.
+{
- *
+    ScopedFastFlag sff{"LuauInterpolatedStringBaseSupport", true};
- * One reason is that LOP_MOVE is added indiscriminately with interpolated strings, whereas
- * standard namecalls only add it where necessary.
- * I am not sure how to fix that, but at least understand why it happens.
- *
- * The second reason, however, is that the registers are completely different for both.
- * Since the conformance tests pass, this might just be a difference without a distinction,
- * like if "format" is being registered before the other strings, for instance.
- *
- * (""):format() codegen:
- * LOADK R0 K0
- * LOADK R2 K1
- * NAMECALL R0 R0 K2
- * CALL R0 2 1
- * RETURN R0 0
- *
- * Interpolated string codegen:
- * LOADK R1 K0
- * LOADK R3 K1
- * NAMECALL R1 R1 K2
- * CALL R1 2 1
- * MOVE R0 R1
- * RETURN R0 0
