Source code of lab on course Compiler Principles (in NJU)

4 directories(lab1, lab2, lab3 and lab4) are listed.

Each directory correspond to one task.

• Lab1: Lexical and syntactic analysis. flex and bison are required to compile .l and .y files.
• Lab2: Semantic analysis.
• Lab3: Intermediate code generation. A intercode interpreter is provided at lab3/irsim.
• Lab4: Machine-code generation. The generated code is spim compatible.

spim can be installed by (on Debian-based Linux distros):

# apt-get install spim

A Qt-version of spim can be found on SPIM MIPS simulator.

The grammar this project used is a simple version of C language. The input files are assumed to be suffixed with .cmm.

The semantic rules are not available here. Contact me if you want a copy of file descripting semantic rules.

$ cd lab*	# substitute * with 1,2,3 or 4
$ make
$ ./parser inputcode.cmm
