* cranelift: Use JIT in runtests Using `cranelift-jit` in run tests allows us to preform relocations and libcalls. This is important since some instruction lowerings fallback to libcall's when an extension is missing, or when it's too complicated to implement manually. This is also a first step to being able to test `call`'s between functions in the runtest suite. It should also make it easier to eventually test TLS relocations, symbol resolution and ABI's. Another benefit of this is that we also get to test the JIT more, since it now runs the runtests, and gets some fuzzing via `fuzzgen` (which uses the `SingleFunctionCompiler`). This change causes regressions in terms of runtime for the filetests. I haven't done any serious benchmarking but what I've been seeing is that it now takes about ~3 seconds to run the testsuite while it previously took around 2 seconds. * Add FMA tests for X86
This crate provides a JIT library that uses Cranelift.
This crate is extremely experimental.
See the example program for a brief overview of how to use this.
