Cosmopolitan v3.3
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.
Major Changes
This release upgrades us to GCC 12.3 and binutils 2.42. The GNU linker
appears to have changed things so that only a single de-duplicated str
table is present in the binary, and it gets placed wherever the linker
wants, regardless of what the linker script says. To cope with that we
need to stop using .ident to embed licenses. As such, this change does
significant work to revamp how third party licenses are defined in the
codebase, using .section .notice,"aR",@progbits.
This new GCC 12.3 toolchain has support for GNU indirect functions. It
lets us support __target_clones__ for the first time. It is used for
optimizing the performance of libc string functions such as strlen and
friends so far on x86, by ensuring AVX systems favor a second codepath
that uses VEX encoding. It shaves some latency off certain operations.
It's a useful feature to have for scientific computing for the reasons
explained by the test/libcxx/openmp_test.cc example which compiles for
fifteen different microarchitectures. Thanks to the upgrades, it's now
also possible to use newer instruction sets, such as AVX512FP16, VNNI.
Experimental support has been added for OpenMP, which lets you whip up
multithreaded mathematical code very easily. It works on all supported
platforms for simple examples like openmp_test.cc but you may run into
issues on MacOS ARM64 with more complicated usage.
Cosmo now uses the %gs register on x86 by default for TLS. Doing it is
helpful for any program that links cosmo_dlopen(). Such programs had
to recompile their binaries at startup to change the TLS instructions.
That's not great, since it means every page in the executable needs to
be faulted. The work of rewriting TLS-related x86 opcodes, is moved to
fixupobj.com instead. This is great news for MacOS x86 users, since we
previously needed to morph the binary every time for that platform but
now that's no longer necessary. The only platforms where we need fixup
of TLS x86 opcodes at runtime are now Windows, OpenBSD, and NetBSD. On
Windows we morph TLS to point deeper into the TIB, based on a TlsAlloc
assignment, and on OpenBSD/NetBSD we morph %gs back into %fs since the
kernels do not allow us to specify a value for the %gs register.
OpenBSD users are now required to use APE Loader to run Cosmo binaries
and assimilation is no longer possible. OpenBSD kernel needs to change
to allow programs to specify a value for the %gs register, or it needs
to stop marking executable pages loaded by the kernel as mimmutable().
Other Changes
- This release fixes
__constructor__, .ctor, .init_array, and .preinit_array so they behave the exact same way as glibc. - The math.h constants no longer use hex notation.
- WinMain() will now ensure
$HOMEand$USERare always defined. - Redbean Fetch redirect with relative URLs has been fixed (#1034)
- The
complex.hheader now works and support is added forstruct ipv6_mreq(#1100) MODE=dbgsupport is now restored, as of c1e18e7- The static yoinks for blink, i.e.
__static_yoink("blink_linux_aarch64"), and__static_yoink("blink_xnu_aarch64"), have been removed. Please build blink from source on your platform to use blink to run cosmo binaries. - There's a now Curve25519() API added to redbean in d50064a and #1096
- Calling
pthread_create()will no longer raise an assertion error if it fails, as of 8ebe2e9 - cosmocc now properly handles dependency output in #1091
- The
__cxa_thread_atexitprototype has been fixed in #1088 - The final remaining libcxx source files have been added in #1089
- cosmocc is now fixed so that it doesn't run fixupobj on text output in #1084
- The STL is now more conformant since std::pair can now be trivial fd75fd1
- Most libc functions are now annotated as
dontthrow, to save on size.
Notes
Cosmopolitan no longer distributes cosmo binaries for QuickJS, because
Fabrice Bellard is now doing it himself on his website. You should use
his binaries instead: https://bellard.org/quickjs/
Errata
cosmocc --versionreports the incorrect gcc version.- cosmocc builds are broken on macos arm (fixed in 77ddf4c)
- Compiling the mono repo on Windows is currently broken due to #1010. In the meantime, use cosmopolitan-3.2.tar.gz
Cosmopolitan v3.2.4
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.
This v3.2.4 release of Cosmopolitan introduces C++ exceptions and RTTI,
which can be enabled by passing the -fexceptions and/or -rtti flags
to your cosmocc compiler.
- b580080 tool/cosmocc: Allow exceptions and rtti (#1074)
- b056634 third_party/libcxxabi: Add test suite (#1076)
- b090966 third_party: Add libunwind (#1053)
- 81ce2e4 Call thread finalizers on exit()
- 94bab16 Add fixes to libunwind (#1069)
- 8b33204 Add LLVM libcxxabi (#1063)
- 6ab0171 Fix aarch64 setjmp abi
If C is your preferred language, then you can use Cosmopolitan garbage
collection via our new gc() macro. To enable this feature, you need to
pass the -mcosmo flag to cosmocc. For example, to say gc(malloc(32))
means that memory will be reclaimed when your function returns, and it
will be reclaimed by pthread_exit() too. There's also defer() which is
generalized and allows any callback. Pointers exist on a shadow stack.
- a4b4551 Bring back
gc()function
Here's some additional developments since the last release:
- df648fb Revert apeinstall.sh binfmt flags (#1072)
- cafea9a Flesh out tool/zsh/mkofs
- 6cb0354 mkofs improvements
- 1609980 zsh mkofs tool
Known Issues
- Compiling the mono repo on Windows is currently broken due to #1010. In the meantime, use cosmopolitan-3.2.tar.gz
Cosmopolitan v3.2.3
This release introduces two new features:
Your cosmo_dlsym() function now returns the raw symbols. You need to
update your code to call cosmo_dltramp() on the result, otherwise it
will crash on Windows. Better yet, just use __ms_abi__ if you can.
- 5e71370 Make breaking change to cosmo_dlsym()
The following fixes have been implemented:
- 5ae2554 Have cosmo_dlopen() request
-z execstackon Linux - aa37a32 Make $prog.ape more reliable on Apple Silicon (#1071)
- 390335e apeinstall/uninstall.sh can use doas (#1062)
- d27a47b Bugfix: ape --help should exit 0 (#1060)
Known Issues
APE Loader has a backwards compatibility regression right now. If you
run ape/apeinstall.sh on Linux then, due to a new binfmt_misc feature,
many old APE binaries that need to load zip assets will refuse to run. You
can fix that on Linux x64 for example by running:
ape/apeuninstall.sh
make -j8 o//ape
sudo mv o//ape/ape.elf /usr/bin/ape
sudo sh -c "echo ':APE:M::MZqFpD::/usr/bin/ape:' >/proc/sys/fs/binfmt_misc/register"
sudo sh -c "echo ':APE-jart:M::jartsr::/usr/bin/ape:' >/proc/sys/fs/binfmt_misc/register"
This will be solved by the next release, to ensure that only modern
APE binaries can use Linux's new P feature. APE is after all designed
to stand the test of time. The intent is to support every APE executable
created since the beginning of the project.
