This commit adds a few odds and ends required to build wasmtime on ARM64 with the new backend. In particular, it adds: - Support for the `Arm64Call` relocation type. - Support for fetching the trap PC when a signal is received. - A hook for `SIGTRAP`, which is sent by the `brk` opcode (in contrast to x86's `SIGILL`). With the patch sequence up to and including this patch applied, `wasmtime` can now compile and successfully execute code on arm64. Not all tests pass yet, but basic Wasm/WASI tests work correctly.
This is the wasmtime-jit crate, which contains JIT-based execution
for wasm, using the wasm ABI defined by wasmtime-environ and the
runtime support provided by wasmtime-runtime.
Most users will want to use the main wasmtime crate instead of using this
crate directly.
