A similar thing is already used in JDK: https://github.com/openjdk/jdk/blob/2a01c798d346656a0ee3553c0964feab75b5dfb6/src/java.base/share/classes/java/lang/invoke/Invokers.java#L622-L624 Extending this for more common use allows doing things like optimizing `Integer.toString(int)`: @Stable static final String[] CONST_STRINGS = {"-1", "0", "1"}; @IntrinsicCandidate public static String toString(int i) { if (isCompileConstant(i) && (i >= -1) && (i <= 1)) { return CONST_STRINGS[i + 1]; } ... ------------- PR Comment: https://git.openjdk.org/jdk/pull/17527#issuecomment-1906379544
