* x64: Add non-SSE4.1 lowerings of ceil/trunc/floor/nearest This commit adds lowerings that work with SSE2 for CLIF `ceil`, `trunc`, `floor`, and `nearest` instructions over vectors. To get these working `insertlane` for float vectors was also implemented for non-SSE4.1 instructions as well. Note that the goal of these lowerings is not speed but rather "it works", so the decompose-to-call-libcalls logic for vector is probably horrendously slow but should at least be correct. * Skip new tests on riscv64 * Update cranelift/codegen/src/isa/x64/inst.isle Co-authored-by: Andrew Brown <andrew.brown@intel.com> --------- Co-authored-by: Andrew Brown <andrew.brown@intel.com>
This crate contains the core Cranelift code generator. It translates code from an intermediate representation into executable machine code.
