The compiler.cfg.instructions vocab contains all instruction classes used for generating CFG:s (Call Flow Graphs).

All instructions are tuples prefixed with '##' and inheriting from the base class insn. Most instructions are coupled with a generic word in cpu.architecture which emits machine code for it. For example, %copy emits code for ##copy instructions.

Instruction classes for moving values around:
##copy

##parallel-copy

##peek

##reload

##replace

##replace-imm

##spill


Control flow:
##branch

##call

##jump

##no-tco
