This is a compiler for a subset of C language. It's a course project in my university.
It supports:
- variables with int, float, char and string types.
- basic arithmetic expressions for int and float types.
- if, if-else, switch-case, while structures
- function calling and recursion.
- a pair of built-in console I/O functions.
- x86 assembly output (for
MASM) - optimization: common subexpression elimination
Now it, the compiler itself, will crash if it is compiled as a 64-bit(x86_64) executable. I'll fix it later.
It's now can only be compiled and running on 32-bit(x86) architecutre. To build the compiler:
# make a folder for project files and building
mkdir build
cd build
# add flags to cc and ld, specifying the architecutre
cmake -D CMAKE_C_FLAGS:string=-m32 -D CMAKE_EXE_LINKER_FLAGS:string=-m32 ..
make
# then you can run it
./mycc [source file]
or
mkdir xcode
cd xcode
cmake -G Xcode ..
# then open the project file generated
It only rely on standrad library. No other libraries are needed.
It can only accept a single input file and output an assembly source file for it as a result. The assembly source can be assembled by MASM. Don't forget to link it with the I/O library, lib/mycclib.asm.
