The problem was that the sign/zero extension was not working with TypeIds, but it was working with register IDs, when emitted. Thus, even when TypeId was uint8, for example, the register could be uint32, so the final instruction emitted was 'movzx eax, eax', for example, which was wrong.

Documentation
Breaking Changes
Breaking the API is sometimes inevitable, what to do?
- See Breaking Changes Guide, which is now part of AsmJit documentation.
- See asmjit tests, they always compile and provide implementation of many use-cases:
- asmjit_test_emitters.cpp - Tests that demonstrate the purpose of emitters.
- asmjit_test_assembler_x86.cpp - Tests targeting AsmJit's Assembler (x86/x64).
- asmjit_test_compiler_x86.cpp - Tests targeting AsmJit's Compiler (x86/x64).
- asmjit_test_instinfo.cpp - Tests that query instruction information.
- asmjit_test_x86_sections.cpp - Multiple sections test.
- Visit our Official Chat if you need a quick help.
