Research direction

Start by tracing the compiler code and target configuration around setMinimumJumpTableEntries. Establish how jump-table support should behave for RISC-V and identify the relevant generated-output or compiler tests; done means the intended behavior is specified and verified without the current INT_MAX workaround.
