Module arch

arch contains the default architectures supported by codegem. An architecture does not need to be in this module to be supported, as the traits that must be implemented are public and can be implemented by other crates wishing to extend codegem’s functionality.

Modules

rv64

rv64 provides a backend for the RISC V 64GC architecture.

urcl

urcl provides a backend for the URCL intermediate language, which can be then used to compile to a variety of targets.

x64

x64 provides a backend for the x86_64 architecture.

LabelledInstructions

VCode

VCodeGenerator

VCodeGenerator is an internal structure used to generate VCode for a given backend.

Enums

Location

Location is a representation of a location in VCode.

VReg

VReg is a representation of a register in VCode.

Traits

Instr

Instr is one of the two traits necessary to implement to define your own backend (the other trait being InstructionSelector). This trait represents an instruction in the target architecture that can be generated by codegem. It also contains various functions related to the generated VCode such as Instr::mandatory_transforms and Instr::emit_assembly.

InstructionSelector

InstructionSelector is the other trait that has to be implemented for a backend. This trait selects instructions to use based on the Operations and Terminators in the provided IR.
