This change upgrades to the latest portcosmo gcc patch
6728fe1a25185560603ca312a8d4352af2a4e515 which lets us avoid needing to
define __tmpcosmo_FOO constants. We're now using an appropriate binutils
version for GCC 11. The older binutils sometimes wasn't able to print
backtraces, due to not being able to find a .debug_ranges section.
This is breaking change for /opt/cosmos libraries :'( due to this weird
"error: need linked-to section for --gc-sections" that pops up.
Please run `make clean` in the monorepo before rebuilding.
This change fixes an issue with the tcflow() magic numbers that was
causing bash to freeze up on Linux. While auditing termios polyfills,
several other issues were identified with XNU/BSD compatibility.
Out of an abundance of caution this change undefines as much surface
area from libc/calls/struct/termios.h as possible, so that autoconf
scripts are less likely to detect non-POSIX teletypewriter APIs that
haven't been polyfilled by Cosmopolitan.
This is a *breaking change* for your static archives in /opt/cosmos if
you use the cosmocc toolchain. That's because this change disables the
ioctl() undiamonding trick for code outside the monorepo, specifically
because it'll lead to brittle ABI breakages like this. If you're using
the cosmocc toolchain, you'll need to rebuild libraries like ncurses,
readline, etc. Yes diamonds cause bloat. To work around that, consider
using tcgetwinsize() instead of ioctl(TIOCGWINSZ) since it'll help you
avoid pulling every single ioctl-related polyfill into the linkage.
The cosmocc script was specifying -DNDEBUG for some reason. It's fixed.
This change integrates e58abc1110b335a3341e8ad5821ad8e3880d9bb2 from
https://github.com/ahgamut/musl-cross-make/ which fixes the issues we
were having with our C language extension for symbolic constants. This
change also performs some code cleanup and bug fixes to getaddrinfo().
It's now possible to compile projects like ncurses, readline and python
without needing to patch anything upstream, except maybe a line or two.
Pretty soon it should be possible to build a Linux distro on Cosmo.
