- Use rec-less, overlay-style overridable recursive attributes (in effect since
NixOS#119942);
- Add decoration hooks over installCheckPhase
- Use doInstallCheck instead of doCheck.
- Directly sets env.ZIG_GLOBAL_CACHE_DIR instead of using preBuild
- Add meta.changelog

- bb53634671 removed the conditionals since firefox-esr-91 and nss <3.69 has been dropped a while ago.
- cb3762857d updated the conditionals to always partition the tests based on the nss_latest version. Chosen that since it will remain future proof.
We want a `libgcc_s.so` to be built by the first stage
cross-compiler (withoutTargetLibc), since that is the compiler which
will compile the target libc.
This commit accomplishes that, by making three changes:
1. Replacing the `targetPlatform.libc == "msvcrt" &&` conditional
with `enableShared`, so that the code which cross-build
`libgcc_s.so` is used for all cross compilers capable of emitting
shared libraries.
2. Removing the `targetPlatform == hostPlatform` guard from the code
which produces the `libgcc` output.
3. Looking for build products in in "lib/${targetPlatform.config}/"
rather than "lib/", so we will find them when cross compiling.
This commit allows `gccCrossStageStatic` to build dynamically-linked
libraries. Since is no longer restricted to building static
libraries its name is no longer appropriate, and this commit also
renames it to the more-accurate `gccWithoutTargetLibc`.
By default, you can't build a gcc that knows how to create dynamic
libraries unless you have already built the targetPlatform libc.
Because of this, our gcc cross-compiler is built in two stages:
1. Build a cross-compiler (gccCrossStageStatic) that can build
only static libraries.
2. Use gccCrossStageStatic to compile the targetPlatform libc.
3. Use the targetPlatform libc to build a fully-capable cross
compiler.
You might notice that this pattern looks very similar to what we do
with `xgcc` in the stdenv bootstrap. Indeed it is! I would like to
work towards getting the existing stdenv bootstrap to handle cross
compilers as well. However we don't want to cripple `stdenv.xgcc`
by taking away its ability to build dynamic libraries.
It turns out that the only thing gcc needs the targetPlatform libc
for is to emit a DT_NEEDED for `-lc` into `libgcc.so`. That's it!
And since we don't use `gccCrossStageStatic` to build anything other
than libc, it's safe to omit the `DT_NEEDED` because that `libgcc`
will never be loaded by anything other than `libc`. So `libc` will
already be in the process's address space.
Other people have noticed this; crosstool-ng has been using this
approach for a very long time:
36ad0b17a7/scripts/build/cc/gcc.sh (L638-L640)
flutter-unwrapped will now not come with engine artifacts in its cache directory(`$out/bin/cache`).
To specify a different cache directory, set FLUTTER_CACHE_DIR.
Flutter's wrapper now sets FLUTTER_CACHE_DIR to set engine artifacts.
The sh file `$out/bin/internal/shared.sh` runs when launching Flutter and calls `"$FLUTTER_ROOT/bin/cache/` instead of our environment variable `FLUTTER_CACHE_DIR`.
I decided not to patch it since the script doesn't require engine artifacts(which are the only thing not added by the unwrapped derivation), so it shouldn't fail, and patching it will just be harder to maintain.
This commit deduplicates libgcc-related boilerplate which appears in
every version of our gcc expression, by moving it into libgcc.nix.
I will be submitting a separate PR which changes this boilerplate,
but that PR will be much easier to review if I can make the change
in just one place.
