FakeJit was the native JIT for architectures without one, but the config already forces those onto the IR interpreter, so CreateNativeJit() now returns that instead. The vertex decoder fallback no longer needs FakeEmitter. JitBlockCache was the block cache of the pre-IR JITs. Its header keeps the debug interface types the IR block caches use. Also removes the JitInterface link hooks only it called, and the JitState fields tied to it. This fixes a null dereference in the ImDebugger memory section, which read GetBlockCache(), always null with the IR JITs. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
