General

• x86_64
• GPLv3-only

Technologies

• Chad C, C99
• Flex/Bison

Train of translation

file -> preprocessor -> as -> link -> exe

NOTE: the compiler front-end should be able to handle the preprocessing someway, but we are not making our own preprocessor. use Frexx or m4

implementation

1. flex parsing
2. bison creates partial syntax trees (since we dont optimize, we can render in relatively small chunks because not all that much context is needed)
3. xolatile magic
