Now that cosmocc is unpacked into a version-specific directory under
cosmocc/, it makes more sense to put the versions in /opt/cosmocc and
maintain a symlink to the currently active one.
The toolchain will now be downloaded going forward from multiple pinned
URLs which have shasums. Either wget or curl must be installed.
This change unblocks #1053
Our dynamic linking implementation is now able to support functions with
dozens of parameters. In addition to having extra integral arguments you
can now pass vector registers using intrinsic types. Lastly, you can now
return multiple values, which is useful for functions returning structs.
It's now possible to pass flags like -Xaarch64-march=armv8.2-a+dotprod
so that cosmocc will use newer ARM ISAs. For AMD64 there's another one
worth mentioning, which looks like this: -Xx86_64-mssse3
This increases risk of fork bomb but is needed to support the NixOS.
Upstream dependencies of APE (uname, mkdir, dd, chmod, gzip, and mv)
will be removed from releases, and deleted from the cosmo.zip server
See #12
- Check `$COSMOCC`, defaulting to `/opt/cosmocc`.
- Try to get the full path of the repo `make.com`. I'm not aware of
a way of getting the path that defines a zsh function, so the best
fallback available is `$PWD`.
Now that our socket system call polyfills are good enough to support
Musl's DNS library we should be using that rather than the barebones
domain name system implementation we rolled on our own. There's many
benefits to making this change. So many, that I myself wouldn't feel
qualified to enumerate them all. The Musl DNS code had to be changed
in order to support Windows of course, which looks very solid so far
This commit and, by extension, PR attempts to update `stb` in the most
straightforward way possible as well as include fixes from main repo's
unmerged PRs for cases rearing their ugly heads during everyday usage:
- stb#1299: stb_rect_pack: Make rect_height_compare a stable sort
- stb#1402: stb_image: Fix "unused invalid_chunk" with STBI_FAILURE_USERMSG
- stb#1404: stb_image: Fix gif two_back memory address
- stb#1420: stb_image: Improve error reporting if file operations fail
within *_from_file functions
- stb#1445: stb_vorbis: Few static analyzers fixes
- stb#1487: stb_vorbis: Fix residue classdata bounding for
f->temp_memory_required
- stb#1490: stb_vorbis: Fix broken clamp in codebook_decode_deinterleave_repeat
- stb#1496: stb_image: Fix pnm only build
- stb#1497: stb_image: Fix memory leaks if stbi__convert failed
- stb#1498: stb_vorbis: Fix memory leaks in stb_vorbis
- stb#1499: stb_vorbis: Minor change to prevent the undefined behavior -
left shift of a negative value
- stb#1500: stb_vorbis: Fix signed integer overflow
Includes additional small fixes that I felt didn't warrant a separate PR.
`o/$mode/*` is passed through as-is. `o/*` other than `$mode` has
`$mode` inserted. `*` has `o/$mode/` prepended.
Really leveraging zsh default tab completion here; if you have built
things with `MODE=` you can leverage that for perfect tab completion
in other modes.
Somehow or another, I previously had missed `BUILD.mk` files.
In the process I found a few straggler cases where the modeline was
different from the file, including one very involved manual fix where a
file had been treated like it was ts=2 and ts=8 on separate occasions.
The commit history in the PR shows the gory details; the BUILD.mk was
automated, everything else was mostly manual.
Using this shell script:
#!/bin/sh
mkdir -p exe
for f in $(findpe); do
if [ -e exe/${f##*/}.exe ]; then
cp $f exe/${f##*/}-$(rand64).exe
else
cp $f exe/${f##*/}.exe
fi
done
rm -f /mnt/videos/microsoft.zip
zip -rj6 /mnt/videos/microsoft.zip exe
echo /mnt/videos/microsoft.zip
Helps file reports with Microsoft about incorrect AV detections.
See #1003
At least in neovim, `│vi:` is not recognized as a modeline because it
has no preceding whitespace. After fixing this, opening a file yields
an error because `net` is not an option. (`noet`, however, is.)
On aarch64 hosts, MODE= is changed to MODE=aarch64, so o// targets don't
work. So On aarch64, get apelink.com out of o/aarch64/. Also prepend ape
when calling it. And finally, fetch with curl when wget isn't installed.
I'm no longer able to reproduce the PE import table corruption that was
previously observed. Since this optimization shaves up to 64kb off each
fat APE binary we build, it's worth turning this back on again, to wait
and see if something breaks, and if so, fix it. At least until the next
release is shipped.
See #965
This change upgrades to superconfigure z0.0.23 which fixes an issue
where the compiler had harmless /home/... paths baked-in, which are
normally only present in the build environment, and usually skipped
over. Sadly on MacOS calling fstatat() on these paths would lead to
cloud file system ops that caused system calls to take a long time.
That's problematic, since cosmocc needs to be a 100% local command.
- Use good ELF technique in cosmo_dlopen()
- Make strerror() conform more to other libc impls
- Introduce __clear_cache() and use it in cosmo_dlopen()
- Remove libc/fmt/fmt.h header (trying to kill off LIBC_FMT)
It turns out my earlier commit ddc08dc974 caused a build with
MODE=aarch64 to fail. The commit changed deathstar.c to link
in code to support a VGA console, but this is not implemented
yet for AArch64. Thanks to @ahgamut for spotting this issue.
