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.
