Firebasic

A compiler for my own peculiar programming language that resembles Visual Basic, but has support for lower-level features such as pointers. It uses another project of mine, NIR, to convert code into an intermediate representation, which is optimized and then dealt with by individual backends.

Requirements:

• nasm (for assembling x64 code)
• gcc (for linking the object files together)

Usage:

firebasic <input files | flags> <output file>
Flags: /win (passes -mwindows to linker)
