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	87d7010495	Improve performance of bitscanning intrinsics ... This change helps spectre more intelligently plan execution, by working around false output dependencies, impacting ops like popcnt bsr and bsf	2021-06-15 06:29:51 -07:00
Justine Tunney	8da931a7f6	Add chibicc ... This program popped up on Hacker News recently. It's the only modern compiler I've ever seen that doesn't have dependencies and is easily modified. So I added all of the missing GNU extensions I like to use which means it might be possible soon to build on non-Linux and have third party not vendor gcc binaries.	2020-12-06 16:20:21 -08:00
Justine Tunney	5aabacb361	Add pseudoteletypewriter to emulator ... https://justine.storage.googleapis.com/emulator628.mp4	2020-08-29 23:51:09 -07:00
Justine Tunney	f4f4caab0e	Add x86_64-linux-gnu emulator ... I wanted a tiny scriptable meltdown proof way to run userspace programs and visualize how program execution impacts memory. It helps to explain how things like Actually Portable Executable works. It can show you how the GCC generated code is going about manipulating matrices and more. I didn't feel fully comfortable with Qemu and Bochs because I'm not smart enough to understand them. I wanted something like gVisor but with much stronger levels of assurances. I wanted a single binary that'll run, on all major operating systems with an embedded GPL barrier ZIP filesystem that is tiny enough to transpile to JavaScript and run in browsers too. https://justine.storage.googleapis.com/emulator625.mp4	2020-08-25 04:43:42 -07:00
