Justine Tunney	3f49889841	Make important improvements ... - Fix preadv() and pwritev() for old distros - Introduce _npassert() and _unassert() macros - Prove that file locks work properly on Windows - Support fcntl(F_DUPFD_CLOEXEC) on more systems	2022-09-14 22:39:08 -07:00
Justine Tunney	868af3f950	Import C++ Standard Template Library ... You can now use the hardest fastest and most dangerous language there is with Cosmopolitan. So far about 75% of LLVM libcxx has been added. A few breaking changes needed to be made to help this go smoothly. - Rename nothrow to dontthrow - Rename nodiscard to dontdiscard - Add some libm functions, e.g. lgamma, nan, etc. - Change intmax_t from int128 to int64 like everything else - Introduce %jjd formatting directive for int128_t - Introduce strtoi128(), strtou128(), etc. - Rename bsrmax() to bsr128() Some of the templates that should be working currently are std::vector, std::string, std::map, std::set, std::deque, etc.	2022-03-22 06:41:54 -07:00

Justine Tunney	e963d9c8e3	Add cpu / mem / fsz limits to build system ... Thanks to all the refactorings we now have the ability to enforce reasonable limitations on the amount of resources any individual compile or test can consume. Those limits are currently: - `-C 8` seconds of 3.1ghz CPU time - `-M 256mebibytes` of virtual memory - `-F 100megabyte` limit on file size Only one file currently needs to exceed these limits: o/$(MODE)/third_party/python/Objects/unicodeobject.o: \ QUOTA += -C16 # overrides cpu limit to 16 seconds This change introduces a new sizetol() function to LIBC_FMT for parsing byte or bit size strings with Si unit suffixes. Functions like atoi() have been rewritten too.	2021-08-13 23:40:53 -07:00
