I'll translate [Paging Implementation](https://os.phil-opp.com/paging-implementation/) into Japanese and this is a tracking issue for it. Please let me know if anyone has already started translating it so that we can avoid...

Restore registers appropriately in early returns

``` $ ./compilium int main() { int a = 1; return a + 2; } Preprocess begin Parse begin [ FuncDef : function{ [ (op= R=(op= R=(op=))), (op= R=(op= L=(op=)...

``` $ echo 'int i = 0;' | ../compilium Preprocess begin Parse begin [ (op= R=(op= R=(op=))) ] Analyze begin `i` has a type: int Gvar: i: int Error: Assertion...

preprocessor macros

- [x] `#define` (simple replace) - [x] `#define` (function-like) - [x] `#ifdef` `#endif` - [x] `#else` - [x] `#` on function-like macro expansion - [ ] `-D` compiler args

- [ ] enum type (treat as int) - [ ] define & use enum constant

- [x] Parse `const` type qualifier - [ ] Check `const` in type checking

Impl compound assignment operators

- [x] *= - [x] /= - [x] %= - [x] += - [x] -= - [x] = - [ ] &= - [ ] ^= - [ ] |=

detect error like this: ``` void func_returns_void () { return 1; // void function should not return int value } ```
