Spidermonkey depends on rustc, so we have the best chance at only
having a single LLVM in the build closure if we use the same LLVM that
rustc depends on.
cc-rs is hardcoded to use the soft-float ABI for riscv64, while
the rest of the system is double-float. This is not just a missing
stub header file - You can't link object files using different
ABIs.
The configurePlatforms mkDerivation parameter needs to be an empty list
to avoid bogus defaults from breaking cross compilation.
Document the parameter to prevent it from being cleaned up.
The use of unspliced llvmPackages in configureFlags was causing an
eval failure when cross-compiling, but since later versions of
Firefox/Spidermonkey can correctly detect clang and libclang without
those arguments being specified, we can just backport that
patch (which applies cleanly), and not have to worry about it any
more.
Also begin to start work on cross compilation, though that will have to
be finished later.
The patches are based on the first version of
https://reviews.llvm.org/D99484. It's very annoying to do the
back-porting but the review has uncovered nothing super major so I'm
fine sticking with what I've got.
Beyond making the outputs work, I also strove to re-sync the packages,
as they have been drifting pointlessly apart for some time.
----
Other misc notes, highly incomplete
- lvm-config-native and llvm-config are put in `dev` because they are
tools just for build time.
- Clang no longer has an lld dep. That was introduced in
db29857eb3, but if clang needs help
finding lld when it is used we should just pass it flags / put in the
resource dir. Providing it at build time increases critical path
length for no good reason.
----
A note on `nativeCC`:
`stdenv` takes tools from the previous stage, so:
1. `pkgsBuildBuild`: `(?1, x, x)`
2. `pkgsBuildBuild.stdenv.cc`: `(?0, ?1, x)`
while:
1. `pkgsBuildBuild`: `(?1, x, x)`
2. `pkgsBuildBuild.targetPackages`: `(x, x, ?2)`
3. `pkgsBuildBuild.targetPackages.stdenv.cc`: `(?1, x, x)`
continuation of #109595
pkgconfig was aliased in 2018, however, it remained in
all-packages.nix due to its wide usage. This cleans
up the remaining references to pkgs.pkgsconfig and
moves the entry to aliases.nix.
python3Packages.pkgconfig remained unchanged because
it's the canonical name of the upstream package
on pypi.
This is the last 60-esr I believe.
- fixed multiple outputs (saves $out 2MB from $out)
- updated the only patch we carry
- symlinked `js` to `js60`, some packages using spidermonkey expects `js`. Might
make it possible to drop 38 in the future.
This is essentially the same as done in
65f2b0a2a3.
For spidermonkey_38 I set --enable-posix-nspr-emulation, as it would
otherwise complain about a wrong NSPR version and that trick seemed to
be successful in spidermonkey_60 anyway.
