* Initial cache memory allocator implementation * Get rid of CallFlag * Perform cache cleanup on exit * Basic cache invalidation * Thats not how conditionals works in C# it seems * Set PTC version to PR number * Address PR feedback * Update InstEmitFlowHelper.cs * Flag clear on address is no longer needed * Do not include exit block in function size calculation * Dispose jump table * For future use * InternalVersion = 1519 (force retest).
