manual-stg-experiment
Manually constructed STG programs compiled with the standard GHC codegen backend.
The samples show various use cases i.e. (de)construction of (un)boxed tuples and (un)lifted ADTs and using FFI.
This experiment suggests that GHC codegen and RTS can be used as generic compiler backend for strict and lazy functional languages.
Build
stack setup
stack build
Usage
stack ghci StgSample.hs
Run a sample in GHCi. i.e.
*StgSample> sampleADT2
It will generate an executable named a.out also will generate the intermediate output files (out.ll, out.s, out.o).
