Compiler Construction

[ssm14293]

Hey guys

I made a compiler for my university assignment. I uses basics rules of parsing and stuff. Here is the Git of my compiler: https://github.com/DragoTechInnovations/PHP-to-ASM-Compiler

 

This compiler is made in PHP and converts my created language to Assembly Language, so yeah its basically an assembler.

Those who want to play around with is fork it, clone it, etc.

 

These are the usage and limitations:

 

Usage:

• compile -h or compile --help
• compile -i e.g: compile -i helloworld.dl * output is an ASM file with timestamp

Syntax:

• variables are initialized as the following: int: a, b, c"
• Only int is supported now 
• A statement should end with a ", even comments
• Comments are only single line, starting from ' 
• variables are required to be initialized
• only +, -, /, * operators are allowed 
• = is used to assign variables 
• floats and decimals are not allowed

 

NB: I made this in less then 2 hours so yeah its not so high-end, plus not an assembly guy.

I made a brainfuck compiler(?) which translates the source code into assembly , so welcome to the club.

I did mine in C++ btw.

 

Also , interpreters are a lot easier to make.

2 hours? Damn that's fast

Yeah. I use PHP alot. So 2 hours. 2.5 at max.

Yeah but PHP is my domain.

Do share the code if you want. Though i wont understand most of it. Dont understand C++

You can add a little bit of code to invoke the system's assembler and probably linker for the user so it can be more convenient. Also it would be nice to follow GCC's flags convention.

You can also split off boilerplate and library code into a separate standard library, written probably part in this language and part in C or C++, for your language that is linked when building the code. This will make the compiler more streamline.

Last you may want to have a look at LLVM as they have a very well established optimization algorithm so you just need to emit either LLVM IL or even just AST and let them handle the optimization, assembler generation and even maybe assembly and linking for you.
