In preparing the back-end to move to ISLE, I detected a number of codegen bugs in the existing code, which are fixed here: - Fix internal compiler error with uload16/icmp corner case. - Fix broken Cls lowering. - Correctly mask shift count for i8/i16 shifts. In addition, I made several changes to operand encodings in various MInst patterns. These should not have any functional effect, but will make the ISLE migration easier: - Encode floating-point constants as u32/u64 in MInst patterns. - Encode shift amounts as u8 and Reg in ShiftOp pattern. - Use MemArg in LoadMultiple64 and StoreMultiple64 patterns.
This crate contains the core Cranelift code generator. It translates code from an intermediate representation into executable machine code.
