internal: Migrate some low-hanging `remove_*` assists to `SyntaxEditor`
|
|
Include version number of libs being built in cargo lib metadata (esp. `librustc_driver*.so`)
Previously, on a non-stable channel, it's possible for two builds from different versioned sources (e.g. 1.84.0 vs 1.84.1) to produce a `librustc_driver*.so` with the same filename hashes. This causes problems with side-by-side installs wrt. linker search paths because 1.84.1 rustc bin and 1.84.0 rustc bin may try to link to the "same" `librustc_driver*.so` (same filename hash) but fail because the contents of the so is actually different.
We try to mitigate this by including the version number of artifacts being built via `__CARGO_DEFAULT_LIB_METADATA` (kind of an ugly hack, but I don't think cargo has a way for us to tell cargo to use a package version override).
Fixes #136701 (mitigates, really).
### Testing
Tested manually[^host] by:
```bash
$ cat src/version
1.86.0
$ ./x build library # w/ compiler profile, (non-stable) dev channel
$ lddtree build/host/stage1/bin/rustc
rustc => build/host/stage1/bin/rustc (interpreter => /lib64/ld-linux-x86-64.so.2)
librustc_driver-ea1b1b2291881cc4.so => build/host/stage1/bin/../lib/librustc_driver-ea1b1b2291881cc4.so
[...]
```
and observing that changing `src/version` to bump a point release causes `librustc_driver*.so` to have a different hash while sources are unmodified otherwise.
```bash
$ cat src/version
1.86.1
$ ./x build library # w/ compiler profile, (non-stable) dev channel
$ lddtree build/host/stage1/bin/rustc
rustc => build/host/stage1/bin/rustc (interpreter => /lib64/ld-linux-x86-64.so.2)
librustc_driver-746badadbcb74721.so => build/host/stage1/bin/../lib/librustc_driver-746badadbcb74721.so
[...]
```
cc `@clan` `@demize` could you check that if you backport this change against 1.84.{0,1} as reported in #136701, that the produced `rustc` binary works, under the context of the Gentoo build system setup?

Complete the list of resources used in rustdoc output
The Nanum Barun Gothic Font was missing in the list and should clearly be mentionned.
Arguably referencing the Rust logos is not really necessary as the file mentions "third party resources" but it doesn't hurt and should make things clearer for anybody who wants to publish their Rust doc.

Build GCC on CI
Previously, we have downloaded a specific commit of GCC and prebuilt it inside Docker using the `build-gccjit.sh` script. This PR removes that scripts and uses the bootstrap GCC step. This allows us to use the `src/gcc` submodule for determining which GCC should be built, and it also moves the logic closer to LLVM, which is also built by bootstrap.
A few things to note:
- The `sccache` option is currently in the `llvm` block, so the GCC build uses `llvm.ccache`, which is a bit weird :) We could either add `gcc.ccache`, or (what I think would be better) to just move `ccache` to the `build` section, as I don't think that it will be necessary to use ccache for LLVM, but not for GCC.
- When the GCC codegen backend is built, it needs to depend on a step that first builds GCC. This is currently done in a hacky way. The proper solution is to create a separate step for the GCC codegen backend, but that is a larger change. Let me know what you think.

We vendor the list of implications, which isn't nice, but t-compiler doesn't want to make rustc_target available to us.

remove `#[rustc_intrinsic_must_be_overridde]`
In https://github.com/rust-lang/rust/pull/135031, we gained support for just leaving away the body. Now that the bootstrap compiler got bumped, stop using the old style and remove support for it.

configure.py: don't instruct user to run nonexistent program
```shell-session
$ ./configure
configure: processing command line
configure:
configure: build.configure-args := []
configure: profile := dist
configure:
configure: writing `config.toml` in current directory
configure:
configure: run `python /mnt/filling/store/nabijaczleweli/code/rust/x.py --help`
```
This is naturally not valid since I don't have a "python" executable (and this will hopefully become more and more true as Python 2 dies out).
./configure knows this since it does `try python3 "$``@"`,`` then `python2.7` &c.
After, this now says
```
configure: run `python3 /mnt/filling/store/nabijaczleweli/code/rust/x.py --help`
```
which is possible, and corresponds to the interpreter actually running.

New attribute parsing infrastructure
Another step in the plan outlined in https://github.com/rust-lang/rust/issues/131229
introduces infrastructure for structured parsers for attributes, as well as converting a couple of complex attributes to have such structured parsers.
This PR may prove too large to review. I left some of my own comments to guide it a little. Some general notes:
- The first commit is basically standalone. It just preps some mostly unrelated sources for the rest of the PR to work. It might not have enormous merit on its own, but not negative merit either. Could be merged alone, but also doesn't make the review a whole lot easier. (but it's only +274 -209)
- The second commit is the one that introduces new infrastructure. It's the important one to review.
- The 3rd commit uses the new infrastructure showing how some of the more complex attributes can be parsed using it. Theoretically can be split up, though the parsers in this commit are the ones that really test the new infrastructure and show that it all works.
- The 4th commit fixes up rustdoc and clippy. In the previous 2 they didn't compile yet while the compiler does. Separated them out to separate concerns and make the rest more palatable.
- The 5th commit blesses some test outputs. Sometimes that's just because a diagnostic happens slightly earlier than before, which I'd say is acceptable. Sometimes a diagnostic is now only emitted once where it would've been twice before (yay! fixed some bugs). One test I actually moved from crashes to fixed, because it simply doesn't crash anymore. That's why this PR Closes #132391. I think most choices I made here are generally reasonable, but let me know if you disagree anywhere.
- The 6th commit adds a derive to pretty print attributes
- The 7th removes smir apis for attributes, for the time being. The api will at some point be replaced by one based on `rustc_ast_data_structures::AttributeKind`
In general, a lot of the additions here are comments. I've found it very important to document new things in the 2nd commit well so other people can start using it.
Closes #132391
Closes #136717
