Pay off more technical debt This makes breaking changes to add underscores to many non-standard function names provided by the c library. MODE=tiny is now tinier and we now use smaller locks that are better for tiny apps in this mode. Some headers have been renamed to be in the same folder as the build package, so it'll be easier to know which build dependency is needed. Certain old misguided interfaces have been removed. Intel intrinsics headers are now listed in libc/isystem (but not in the amalgamation) to help further improve open source compatibility. Header complexity has also been reduced. Lastly, more shell scripts are now available. 2022-09-12 23:10:38 -07:00			`#include "libc/intrin/bsr.h"`

Import some Lua documentation I personally find it easier to read the documentation in Emacs using JavaDoc style comments. 2021-08-22 15:02:18 -07:00			`#define ThomPikeCont(x) (0200 == (0300 & (x)))`

Rename _bsr/_bsf to bsr/bsf Now that these functions are behind _COSMO_SOURCE there's no reason for having the ugly underscore anymore. To use these functions, you need to pass -mcosmo to cosmocc. 2024-03-04 17:33:26 -08:00			`#define ThomPikeMsb(x) ((255 & (x)) < 252 ? bsr(255 & ~(x)) : 1)`
Fix warnings This change fixes Cosmopolitan so it has fewer opinions about compiler warnings. The whole repository had to be cleaned up to be buildable in -Werror -Wall mode. This lets us benefit from things like strict const checking. Some actual bugs might have been caught too. 2023-09-01 20:49:13 -07:00			`#define ThomPikeMerge(x, y) ((x) << 6 \| (077 & (y)))`
