The Simple C Compiler project started as my final project for my Introduction to Programming Languages class at IUPUI (CSCI-35500). However, the program for the class just implemented the C parser; it didn't implement the compiler which actually does semantic analysis on the code. I'm currently working on finishing the rest of the program so I actually have a working C compiler, not just a fancy C parser.
Parsing:
- Parse structs and unions
- Parse enumerations
- Parse initializer lists
- Parse
typedefstatements - Complex and imaginary types (maybe?)
Compiling:
- Compile-time expression evaluation
- Runtime expression evaluation
- Local variables and scope resolution
- Integer promotion and type casting
- Function calls and stack frame
- Return values
- Goto statements and labels
- If statements
- While, do/while, and for loops
- Switch/case statements
- Const variables
- Bit fields (maybe?)
These features are not listed in any particular order, and the list is not exhaustive.
The provided makefile should handle all of the compiling and linking of objects. However, you will need to install the Flex Lexer and the Bison Parser, as SCC uses Flex and Bison to generate the parser. For Debian Linux distributions, this is as simple as:
sudo apt-get install flex
sudo apt-get install bison
Once Flex and Bison are installed, simply type:
make
from the source directory, and everything should compile and link. To rebuild the project from scratch, type:
make clean
make
Usage:
./scc.out <c-file>
Right now, calling the parser with a C file will parse the file and print out the abstract syntax tree to standard output. If there is an error parsing the C file (like invalid syntax), it will display a "syntax error!" message.
