Project Organization
--------------------
* **`/`** - Project root - project files and scripts, `include` path points here
* **asmjit** - AsmJit source code and headers
* **core** - Core API, backend independent except relocations
* **support** - Support classes and functions
* **arm** - ARM specific API, designed to be common for both AArch32 and AArch64
* **a64** - AArch64 specific API, used only by AArch64 backends
* **x86** - X86 specific API, used only by X86 and X64 backends
* **ujit** - Universal JIT API
* **asmjit-testing** - Unit tests, integration tests, and benchmarks (don't embed in your project)
* **commons** - Common utilities shared between tests and benchmarks
* **bench** - Benchmarks
* **tests** - Unit tests and integration tests
* **db** - Instruction database
* **tools** - Tools used to re-regenerate generated files (instruction DB, enum strings)

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](./asmjit-testing/tests/asmjit_test_emitters.cpp) - Tests that demonstrate the purpose of emitters
* [asmjit_test_assembler_x86.cpp](./asmjit-testing/tests/asmjit_test_assembler_x86.cpp) - Tests targeting AsmJit's Assembler (x86/x64)
* [asmjit_test_compiler_x86.cpp](./asmjit-testing/tests/asmjit_test_compiler_x86.cpp) - Tests targeting AsmJit's Compiler (x86/x64)
* [asmjit_test_instinfo.cpp](./asmjit-testing/tests/asmjit_test_instinfo.cpp) - Tests that query instruction information
* [asmjit_test_x86_sections.cpp](./asmjit-testing/tests/asmjit_test_x86_sections.cpp) - Multiple sections test
