Remove tests on x86_64-darwin to avoid specific false errors due to
the way Hydra runners are set up for this architecture.
On this platform, on Hydra runners we see: `SIMD support requires
SSE3, SSSE3, SSE4.1, and SSE4.2 on x86_64.` present in all failing
tests.
Thus, do not run tests on this platform to avoid false reports of this
derivation being broken, because Hydra runners are set up in a way
that this CPU features are not available.
An example of automation marking this derivation as broken because the
Hydra runs were reporting failures: 03bc571744.
Provide a specific path for the v8 project, so `wasmtime` dependency
`rusty_v8` can find it and does not need to download the static
library, what would break build hermetism.
Rust 1.50.0 incorporated a Cargo change (rust-lang/cargo#8937) in
which cargo vendor erroneously changed permissions of vendored
crates. This was fixed in Rust
1.51.0 (rust-lang/cargo#9131). Unfortunately, this means that all
cargoSha256/cargoHashes produced during the Rust 1.50.0 cycle are
potentially broken.
This change updates cargoSha256/cargoHash tree-wide.
Fixes#121994.
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)`
Changes the default fetcher in the Rust Platform to be the newer
`fetchCargoTarball`, and changes every application using the current default to
instead opt out.
This commit does not change any hashes or cause any rebuilds. Once integrated,
we will start deleting the opt-outs and recomputing hashes.
See #79975 for details.
this upgrade fixes a problem with running trapping WebAssembly code
for me:
```
error: failed to process main module `_out/issue36.wasm`
caused by: Instantiation error: Trap occurred while invoking start function: wasm trap: unreachable, source location: @2eb9
```
