A number of places in the x64 backend make use of 128-bit constants for various wasm SIMD-related instructions although most of them currently use the `x64_xmm_load_const` helper to load the constant into a register. Almost all xmm instructions, however, enable using a memory operand which means that these loads can be folded into instructions to help reduce register pressure. Automatic conversions were added for a `VCodeConstant` into an `XmmMem` value and then explicit loads were all removed in favor of forwarding the `XmmMem` value directly to the underlying instruction. Note that some instances of `x64_xmm_load_const` remain since they're used in contexts where load sinking won't work (e.g. they're the first operand, not the second for non-commutative instructions).
This crate contains the core Cranelift code generator. It translates code from an intermediate representation into executable machine code.
