While `pc` is not particularly wrong on x86_64, it's nonsensical on
other supported platforms, namely aarch64 and riscv64.
For consistency, we now don't use this vendor anymore, regardless of the
platform.
Within the LLVM project, we now build as `$arch-serenity`. This is
enough in most cases, the only place where we have to specify a vendor
is the target .cfg file where we use `$arch-unknown-serenity`.
When building GCC and friends, again we simply identify as
`$arch-serenity` and this is enough.
As a result, the tools in Toolchain/Local/$arch/bin are now named after
this pattern: `$arch-serenity-$tool`.
These changes affect the toolchain build scripts, serenity's build
scripts and the Ports.
The last place where we should see `x86_64-pc-serenity` is the output of
`config.sub`, which assume the vendor is `pc` on vendor-less `x86*`
triples. So `x86_64-serenity` is expanded to `x86_64-pc-serenity`,
luckily enough and AFAICT, the whole GNU ecosystem considers `pc`,
`unknown` and vendor-less target triples the same. So `configure`
shouldn't have an issue finding the right tools anyway.
The gn files were edited with sed and are not tested.
This commit also includes a check in `Meta/serenity.sh` to give a nicer
error message when trying to build the system with an old toolchain.
----
To test this patch, on a clean tree I:
- Ran `./Meta/serenity.sh x86_64 GNU`
- Ran `./Toolchain/BuildJakt.sh`
- Tested these ports: python3(configure based), libjxl(cmake based) and
rizin(meson based)
- Also booted on aarch64 and risv64
I also repeated the steps above with a Clang toolchain.
On a working tree I tested all the affected ports, the results are:
- tinycc build fine but can't compile programs, I observed the same on
master.
- gdb and epsilon don't build but report the same errors as on master.
- I manually edited the libgpg-error, and it builds fine.
- The gcc port works fine.
YouCompleteMe is a plugin for Vim which provides code-completion
functionality. This change adds a configuration file which makes
YouCompleteMe aware of which compile flags to use with clangd.
