This commit implements the stack limit checks in cranelift for the AArch64 backend. This gets the `stack_limit` argument purpose as well as a function's global `stack_limit` directive working for the AArch64 backend. I've tested this locally on some hardware and in an emulator and it looks to be working for basic tests, but I've never really done AArch64 before so some scrutiny on the instructions would be most welcome!
Wasmtime Embedding API
The wasmtime crate is an embedding API of the wasmtime WebAssembly runtime.
This is intended to be used in Rust projects and provides a high-level API of
working with WebAssembly modules.
If you're interested in embedding wasmtime in other languages, you may wish to
take a look a the C embedding API instead!
