Add `dontthrow` attribute to most libc functions This will help C++ code that uses exceptions to be tinier. For example, this change shaves away 1000 lines of assembly code from LLVM's libcxx, which is 0.7% of all assembly instructions in the entire library. 2024-01-09 09:26:03 +00:00			`int systemvpe(const char , char const[], char *const[]) libcesque;`
Make improvements - Introduce portable sched_getcpu() api - Support GCC's __target_clones__ feature - Make fma() go faster on x86 in default mode - Remove some asan checks from core libraries - WinMain() now ensures $HOME and $USER are defined 2024-02-01 11:39:46 +00:00			`char *GetProgramExecutableName(void);`
Introduce support for trapping math The feenableexcept() and fedisableexcept() APIs are now provided which let you detect when NaNs appear the moment it happens from anywhere in your program. Tests have also been added for the mission critical math functions expf() and erff(), whose perfect operation has been assured. See examples/trapping.c to see how to use this powerful functionality. 2024-04-30 20:32:23 +00:00			`void unleaf(void);`
