Jason Compiler

This is a sysY compiler for the Compiling Principles. It could generate two kind of intermediate representations which is Eeyore and Tigger and the corresponding RISC-V instructions from sysY language

Compilation

First use flex.

$ flex -o lex.yy.cpp source.l

Then use bison

$ bison -d -o source.tab.cpp source.y

Finally compile with g++ (because makefile is prohibited by the platform)

g++ -Wno-register -O2 -lm -std=c++17 main.cpp driver.cpp global.cpp ir.cpp irgen.cpp lex.yy.cpp source.tab.cpp -o main -Idirs

Usage

./main -S [-e|-t] testcase.sy [-o testcase.S]
