Breaking Changes

----------------

Breaking the API is sometimes inevitable, what to do?

  * See [Breaking Changes Guide](https://asmjit.com/doc/group__asmjit__breaking__changes.html), which is now part of AsmJit documentation

  * See asmjit tests, they always compile and provide implementation of many use-cases:

    * [asmjit_test_emitters.cpp](./test/asmjit_test_emitters.cpp) - Tests that demonstrate the purpose of emitters

    * [asmjit_test_assembler_x86.cpp](./test/asmjit_test_assembler_x86.cpp) - Tests targeting AsmJit's Assembler (x86/x64)

    * [asmjit_test_compiler_x86.cpp](./test/asmjit_test_compiler_x86.cpp) - Tests targeting AsmJit's Compiler (x86/x64)

    * [asmjit_test_instinfo.cpp](./test/asmjit_test_instinfo.cpp) - Tests that query instruction information

    * [asmjit_test_x86_sections.cpp](./test/asmjit_test_x86_sections.cpp) - Multiple sections test.

Project Organization

--------------------

  * **`/`**        - Project root

    * **src**      - Source code

      * **asmjit** - Source code and headers (always point include path in here)

        * **core** - Core API, backend independent except relocations

        * **arm**  - ARM specific API, used only by ARM and AArch64 backends

        * **x86**  - X86 specific API, used only by X86 and X64 backends

    * **test**     - Unit and integration tests (don't embed in your project)

    * **tools**    - Tools used for configuring, documenting, and generating files

Ports

-----

  * [ ] 32-bit ARM/Thumb port (work in progress)

  * [ ] RISC-V port (not in progress, help welcome)
