Cosmopolitan v3.9.0
Cosmopolitan Libc makes C a build-once run-anywhere language, like Java, except it doesn't need an interpreter or virtual machine. Instead, it reconfigures stock GCC and Clang to output a POSIX-approved polyglot format that runs natively on Linux + Mac + Windows + FreeBSD + OpenBSD + NetBSD + BIOS with the best possible performance and the tiniest footprint imaginable. For further details, read Cosmopolitan Third Edition, the Cosmo README, and the Cosmopolitan Toolchain README. Prebuilt software is available on https://cosmo.zip/

Instead, it reconfigures stock GCC and Clang to output a POSIX-approved polyglot format that runs natively on Linux + Mac + Windows + FreeBSD + OpenBSD + NetBSD + BIOS with the best possible performance and the tiniest footprint imaginable.

Improvements
Your malloc() function is now more scalable on Linux Aarch64 and other
platforms, where it previously was not working as well as advertised.
- 0a79c69 Make malloc scalable on all platforms
Cosmopolitan Bash now works better on Windows. For example, if you start
a process that redirects stderr to a file, then your entire process tree
will now be able to cooperatively write to that file. When you update it
is recommended that you upgrade all your cosmos binaries at once.
Improvements have been made to cosmocc and libcxx which made it possible
for us to compile Clang as an APE binary.
- 77d3a07 Fix std::filesystem
- 0d7c272 Don't use sendfile() in libcxx
- 18964e5 Fix remove() directory on Windows
- 6ac3d3b Add precompiled header support to cosmocc
- f8cfc89 Allow -c to be specified with -E in cosmocc
- 01b09bc Support printf %n directive
- 3dab207 Remove mkfifo() prototype
- d0360bf Introduce cosmoranlib
Some upstream dependencies have been updated. In particular, Musl locale
handling is more true to the way it works upstream. You may need to have
setlocale(LC_ALL, "C.UTF-8") in your main() function for certain POSIX
functions to work the same way they did previously by default.
- bb815ea Update Musl Libc code
- ff1a0d1 Upgrade to superconfigure z0.0.51
- 3fd275f Import optimized routines changes to exp10
- d40acc6 Detect more x86 features
Additional Changes
- a80ab3f Implement bf16 compiler runtime library
- 8d8aecb Avoid legacy instruction penalties on x86
- 24666e1 Add nightly cosmocc (artifact) builds (#1254)
- 3119416 Remove .internal from more header filenames
- 7499367 Ignore -Wimplicit-function-declaration in cosmocc
- 9ebacb7 Convert GCC 14 errors back to warnings (#1247)
- e18fe1e Freshen build/bootstrap/cocmd
- cf1559c Remove __threaded variable
Cosmopolitan v3.6.2
Your cosmocc toolchain is now able to produce tinier binaries. For small
programs, passing -mtiny can cut binary size in half. In fact oftentimes
our fat binaries end up being half the size of statically linked
linux-only executables that use glibc. You can also pass -mdbg to link a
debug version of the cosmopolitan runtime.
- 642e9cb Introduce cosmocc flags -mdbg -mtiny -moptlinux
Your cosmocc toolchain, which was recently built with GCC 14.1, is now
itself being compiled with GCC 14.1. We've also enabled the -fanalyzer
flag, which has been helping us find bugs.
- fb54604 Upgrade to superconfigure z0.0.48
- f147d3d Fix some static analysis issues
- 32292ae Fix build determinism issue
- 81dd963 Fix bug in tool/decode/zip
Your fork() function will now go much faster when it's used by many
threads at once.
- cdfcee5 Properly serialize fork() operations
Some additional improvements:
Cosmopolitan v3.6.1
- f25fbba Use libcxx abi v1
- d3a13e8 Improve lock hierarchy
- fbc4b03 Restore support for AMD K8
- 2c4b887 Add special errno handling to libcxx
- 3915ca0 Have cosmocc define -Wno-implicit-int

- 1020dd4 bzero() should be defined without special defines
Cosmopolitan v3.6.0

- This release upgrades libcxx to the latest code at HEAD from the LLVM project.
- The mono repo now uses GNU C23 and C++23.
