pascal-compiler

this is a pascal compiler which can translate pascal code to x86 assembly language. easy to use, try it!

compile and run

this project can only run in Linux, make sure you have flex and bison. if you don't have, please install:

sudo apt-get install flex
sudo apt-get install bison

after install, you can run it

make
./main x.spl y.asm
# such as: ./main test/test2.spl test/test2.asm
# you can input 'make clean' to delele .o file
