Improve the state of handwritten assembly files (#865) * Format all handwritten asm and document some * Use c preprocessor for constants * Fix * Fix PI_STATUS_ERROR, some label improvements * Avoid hi/lo for constants * Some more comments * Properly mark functions as functions and their sizes * Fix merge * Improvements * Review suggestions, rework procedure start/end macros to be more like libreultra * Move IPL3 symbol definitions into ipl3.s * Fix undefined_syms, add include and language guards to asm.h and fix the comment in gbi.h * Consistent hex capitalization, add some MIPS builtin defines to CC_CHECK to behave properly * Add -no-pad-sections assembler option and clean up alignment in gu files and bzero * Further suggestions and improvements * Matrix conversion function clarifications * Fix passing AVOID_UB to gcc * Suggestions * Suggestions, global interrupt mask improvements * Further suggestions, interrupt mask comments * Comments fixes, rdb.h * Switch from # comments to // comments, remove unnecesary .set gp=64 directives * Further review suggestions * Missed one 2022-04-30 23:03:22 +00:00			`#include "ultra64/asm.h"`
