The main goal of the asm project group is to design and implement an asm! macro using a syntax that we feel we can maintain, easily write, and stabilize.
The project group has the following additional goals:
- to provide a transition path for existing users of the unstable
asm!macro. - to ensure that the chosen
asm!syntax is portable to different compiler backends such as LLVM, GCC, etc. - to provide a fallback implementation on compiler backends that do not support inline assembly natively (e.g. Cranelift).
- to initially support most major architectures (x86, ARM, RISC-V) with the intention of extending to other architectures in the future.
With a lower priority, the project group also intends to tackle the following secondary, future goals:
- support for module-level assembly (
global_asm!). - support for naked functions (
#[naked]).
