Get codebase completely working with LLVM You can now build Cosmopolitan with Clang: make -j8 MODE=llvm o/llvm/examples/hello.com The assembler and linker code is now friendly to LLVM too. So it's not needed to configure Clang to use binutils under the hood. If you love LLVM then you can now use pure LLVM.

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

Get Redbean fork() working on the New Technology Now that we have understandable system call tracing on Windows, this change rewrites many of the polyfill internals for that platform, to help things get closer to tip top shape. Support for complex forking scenarios had been in a regressed state for quite some time. Now, it works! Subsequent changes should be able to address the performance.

[WIP] Threading phase 2 (#301) * Exponential back-off * Removed "native" specifier * Abstract away Futex for cthread * Complete setup for TLS (including main thread)

Make improvements - Document redbean's argon2 module - Fix regressions in cthreads library - Make testlib work better with threads - Give the cthreads library lots of love - Remove some of the stdio assembly code - Implement getloadavg() across platforms - Code size optimizations for errnos, etc. - Only check for signals in main thread on Windows - Make errnos for dup2 / dup3 consistent with posix This change also fixes a bug in the argon2 module, where the NUL terminator was being included in the hash encoded ascii string. This shouldn't require any database migrations to folks who found this module and productionized it, since the argon2 library treats it as a c string.
