* set build options * remove COMPARE and MDOERN_* switches * remove tools makefile * AR patching is gone too since we want a fullly decomped version * AR is modern * remove cwd changes * edit my own tool to fix compile errors * compile files generated with my own tool instead of the originals * inline modern_gcc makefile * port mips toolchain detection logic * add util.mk for find-command * remove forced AR order and strip/mdebug removal commands * add -mabi=32 to as flags * formatting changes * add clang format files * formatting changes * make libgultra CI work * install mips gcc too * add format check tools * Add formatting to CI * Add CI (#4) * make libgultra CI work * install mips gcc too * remove make setup --------- Co-authored-by: someone2639 <someone2639@gmail.com> * we don't use clang-tidy * use 120 width for formatting * a * address clang-tidy messing up * test * align consecutive macros and declarations * only align macros for now * SpaceAfterCStyleCast: false * format headers too * remove cast space switch because its false by default * pointers on left * AlignConsecutiveBitFields: true * install clang-format and clang-tidy on gh actions * and clang-tools * show diff in format check tool * make CI work --------- Co-authored-by: someone2639 <someone2639@gmail.com> 🙏
