Module compiler 

Compiler infrastructure

The Fidget compiler operates in several stages:

• A math graph (specified as a Context and Node) is flattened into an SsaTape, i.e. a set of operations in single-static assignment form.
• The SsaTape goes through register allocation and becomes a RegTape, planned with some number of registers.

Structs

RegTape

Low-level tape for use with the Fidget virtual machine (or to be lowered further into machine instructions).

RegisterAllocator

Cheap and cheerful single-pass register allocation

SsaTape

Instruction tape, storing opcodes in SSA form

Enums

RegOp

Operations used in register-allocated tapes

RegOpDiscriminants

RegOp discriminant value

SsaOp

Basic operations that can be performed in a tape
