Components

Component	Demo
Token generation / Lexer	test1.out
Parser	struct.go ➡️ struct.html
IR generation	scope.go ➡️ scope.ir
Code generation	pascalTriangle.ir ➡️ pascalTriangle.asm

Setting up

Run ./scripts/setup.sh from the root directory of the project to set up the pre-commit git hooks.

Dependencies

• gocc

Build

The following should generate relevant binaries inside the directory bin -

make

The generated binary bin/gogo can be used as follows -

Usage: gogo (-r | -r2s | -s) <filename>
  -p	Generates rightmost derivations used in bottom-up parsing
  -r	Generates IR instructions from go program
  -r2s  Generates the MIPS assembly from IR
  -s	Generates MIPS assembly from go program

NOTE: The generated MIPS assembly has been tested to work on SPIM MIPS32 simulator.

Testing

The tests can be built via -

make test
