scl-compiler's Introduction

Simplified C Language (SCL) Compiler

Setup Docker environment

Scripts make build-docker and make run-docker are given for easiness of use.

Build and execute

Use make all to build and ./bin/scl filename to compile. You can run make test to run some test scripts.

Usage

Compile with ./bin/sclc input.csl output. This will generate the binary output. If you also want the assembly code, run ./bin/sclc input.csl output --asm that will generate both output and output.asm.

An util to load in the processor memory is provided. Run ./bin/bin2vhdl output output.txt and it will convert the binary output to VHDL code that loads the binary into the memory.

Compiler Flags

  • --asm outputs the assembly file
  • --asm_comments adds comments to the assebly file
  • --print_ast outputs the symbolic tree
  • --dialect=raw or --dialect=ABI change the register naming. Raw (default) uses only x0-x31. ABI uses names such as ra, zero, sp, etc.. The RISC-V Simulator used only accepts Assembly in ABI naming.

Experiments

The experiments from the report are reproducible with ./test/run-experiments.sh.
