Currently a large switch-case is generated in uwin-remill. This is fine with small executables, but fails miserably with larger ones (order of 100,000s of recompiled functions) due to scalability problems in modern C++ compilers (see gcc bug). Either using binary trees or perfect hashing might be a good idea.

(For now perfec hashing seems very promising)
