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_x86_asm.cpp - Tests that demonstrate the purpose of emitters.
  • asmjit_test_x86_sections.cpp - Multiple sections test.
  • asmjit_test_compiler_x86.cpp - Tests targeting AsmJit's Compiler (x86/x64).
• Visit our Official Chat if you need a quick help.

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.

TODO

• Core:
  • Add support for user external buffers in CodeBuffer / CodeHolder.
  • Register allocator doesn't understand register pairs, affected instructions:
    • v4fmaddps, v4fmaddss, v4fnmaddps, v4fnmaddss
    • vp4dpwssd, vp4dpwssds
    • vp2intersectd, vp2intersectq
• Ports:
  • ARM/Thumb/AArch64 support.
