Get rid of RunCompiler
The various `set_*` methods that have been removed can be replaced by setting the respective fields in the `Callbacks::config` implementation. `set_using_internal_features` was often forgotten and it's equivalent is now done automatically.
|
|
It has become nothing other than a wrapper around run_compiler.
|
|
They can both be set inside the config callback too.

Properly note when query stack is being cut off
cc #70953
also, i'm not certain whether we should even limit this at all. i don't see the problem with printing the full query stack, apparently it was limited b/c we used to ICE? but we're already printing the full stack to disk since #108714.

Respect --sysroot for rustc -vV and -Cpasses=list
This is necessary when the specified codegen backend is in a custom sysroot.
Fixes https://github.com/rust-lang/rust/issues/135165
|
|
|
|
Setting up the argument parser to parse no arguments is a tiny bit of wasted
work, but avoids an otherwise-unnecessary special case.
In particular, this lets us avoid having to deal with multiple different APIs
to determine whether the compiler is nightly or not.

when running `tests/ui/panics/default-backtrace-ice.rs locally it gave this error:

```
this is a regression from setting RUST_BACKTRACE=1 by default. we need to turn off the new behavior when running UI tests so that they reflect our dist compiler. normally that's done by checking `sess.unstable_opts.ui_testing`, but this happens extremely early in the compiler before we've expanded arg files. do an extremely simple hack that doesn't work in all cases - we don't need it to work in all cases, only when running UI tests.
|
|
A dev build almost certainly means that whoever's built the compiler
has the opportunity to rerun it to collect a more complete trace. So
we don't need to default to a complete trace; we should hide irrelevant
details by default.
|
|
Instead use dcx.abort_if_error() or guar.raise_fatal() instead. These
guarantee that an error actually happened previously and thus we don't
silently abort.

refactor: replace &PathBuf with &Path to enhance generality
- According to [style.md](https://github.com/rust-lang/rust/blob/master/src/tools/rust-analyzer/docs/dev/style.md#useless-types):
> More generally, always prefer types on the left
```rust
// GOOD BAD
&[T] &Vec<T>
&str &String
Option<&T> &Option<T>
&Path &PathBuf
```

`rustc_span::symbol` defines some things that are re-exported from
`rustc_span`, such as `Symbol` and `sym`. But it doesn't re-export some
closely related things such as `Ident` and `kw`. So you can do `use
rustc_span::{Symbol, sym}` but you have to do `use
rustc_span::symbol::{Ident, kw}`, which is inconsistent for no good
reason.
This commit re-exports `Ident`, `kw`, and `MacroRulesNormalizedIdent`,
and changes many `rustc_span::symbol::` qualifiers in `compiler/` to
`rustc_span::`. This is a 200+ net line of code reduction, mostly
because many files with two `use rustc_span` items can be reduced to
one.

Split up attribute parsing code and move data types to `rustc_attr_data_structures`
This change renames `rustc_attr` to `rustc_attr_parsing`, and splits up the parsing code. At the same time, all the data types used move to `rustc_attr_data_structures`. This is in preparation of also having a third crate: `rustc_attr_validation`
I initially envisioned this as two separate PRs, but I think doing it in one go reduces the number of ways others would have to rebase their changes on this. However, I can still split them.
r? `@oli-obk` (we already discussed how this is a first step in a larger plan)
For a more detailed plan on how attributes are going to change, see https://github.com/rust-lang/rust/issues/131229
Edit: this looks like a giant PR, but the changes are actually rather trivial. Each commit is reviewable on its own, and mostly moves code around. No new logic is added.

A bunch of cleanups (part 2)
Just like https://github.com/rust-lang/rust/pull/133567 these were all found while looking at the respective code, but are not blocking any other changes I want to make in the short term.
|
|
It only exists to pass some information from one part of the driver to
another part. We can directly pass this information to the function that
needs it to reduce the amount of mutation of the Session.
|
|
|
|
|
|
|
|
It was inconsistently done (sometimes even within a single function) and
most of the rest of the compiler uses fatal errors instead, which need
to be caught using catch_with_exit_code anyway. Using fatal errors
instead of ErrorGuaranteed everywhere in the driver simplifies things a
bit.

Remove `-Zshow-span`.
It's very old (added in #12087). It's strange, and it's not clear what its use cases are. It only works with the crate root file because it runs before expansion. I suspect it won't be missed.

Print name of env var in `--print=deployment-target`
The deployment target environment variable is OS-specific, and if you're in a place where you're asking `rustc` for the deployment target, you're likely to also wanna know the name of the environment variable. I myself wanted this for some code I'm working on in bootstrap, for example.
Behaviour before this PR:
```console
$ rustc --print=deployment-target --target=aarch64-apple-darwin
deployment_target=11.0
$ rustc --print=deployment-target --target=aarch64-apple-visionos
deployment_target=1.0
```
Behaviour after this PR:
```console
$ rustc --print=deployment-target --target=aarch64-apple-darwin
MACOSX_DEPLOYMENT_TARGET=11.0
$ rustc --print=deployment-target --target=aarch64-apple-visionos
XROS_DEPLOYMENT_TARGET=1.0
```
My _belief_ is that this option is extremely rarely used in general, and a GitHub search for "rustc print deployment-target" seems to confirm this, it revealed only the following actual pieces of code using this:
- https://github.com/PyO3/maturin/blob/b292ef69349f2a56cb8ab1b59fda0be3d3b9f138/src/build_context.rs#L1199-L1220
- https://github.com/rust-lang/cc-rs/blob/daab9244b03e244c4f2511944870d719c443f61f/src/lib.rs#L3422-L3426
`maturin` does `.split('=').last()`, so it will continue to work after this change, but `cc v1.0.84` did `.strip_prefix("deployment_target=")` since [this PR](https://github.com/rust-lang/cc-rs/pull/848), so it would break. That's _probably_ fine though, it was broken in a lot of scenarios anyway, and [got](https://github.com/rust-lang/cc-rs/pull/901) [reverted](https://github.com/rust-lang/cc-rs/pull/943) in `v1.0.85`.
So while this is _technically_ a breaking change, I really doubt that anyone is going to observe it, so it's probably fine.

Rename `-Zparse-only`
It's a misleading name.
r? ````@estebank````
|
|
I was surprised to find that running with `-Zparse-only` only parses the
crate root file. Other files aren't parsed because that happens later
during expansion.
This commit renames the option and updates the help message to make this
clearer.

Some more refactorings towards removing driver queries
Follow up to https://github.com/rust-lang/rust/pull/127184
## Custom driver breaking change
The `after_analysis` callback is changed to accept `TyCtxt` instead of `Queries`. The only safe query in `Queries` to call at this point is `global_ctxt()` which allows you to enter the `TyCtxt` either way. To fix your custom driver, replace the `queries: &'tcx Queries<'tcx>` argument with `tcx: TyCtxt<'tcx>` and remove your `queries.global_ctxt().unwrap().enter(|tcx| { ... })` call and only keep the contents of the closure.
## Custom driver deprecation
The `after_crate_root_parsing` callback is now deprecated. Several custom drivers are incorrectly calling `queries.global_ctxt()` from inside of it, which causes some driver code to be skipped. As such I would like to either remove it in the future or if custom drivers still need it, change it to accept an `&rustc_ast::Crate` instead.

I think the control flow in this function is complicated and confusing,
largely due to the use of two booleans `print_formatted` and
`fallback_to_println` that are set in multiple places and then used to
guide proceedings.
As well as hurting readability, this leads to at least one bug: if the
`write_termcolor_buf` call fails and the pager also fails, the function
will try to print color output to stdout, but that output will be empty
because `write_termcolor_buf` failed. I.e. the `if fallback_to_println`
body fails to check `print_formatted`.
This commit rewrites the function to be neater and more Rust-y, e.g. by
putting the result of `write_termcolor_buf` into an `Option` so it can
only be used on success, and by using `?` more. It also changes
terminology a little, using "pretty" to mean "formatted and colorized".
The result is a little shorter, more readable, and less buggy.

It's not necessary because `show_md_content_with_pager` is only ever
called if `is_terminal` is true.

`bat` is known as `batcat` on Ubuntu and Debian, not `catbat`.

busybox less does not support the -r flag and less(1) says:
USE OF THE -r OPTION IS NOT RECOMMENDED.

Several custom drivers are incorrectly calling queries.global_ctxt()
from inside of it, which causes some driver code to be skipped. As such
I would like to either remove it in the future or if custom drivers
still need it, change it to accept an &rustc_ast::Crate instead.
|
|
There is no other query that may need to be called at that point anyway.
|
|
We now only exit the GlobalCtxt when calling a callback and all the way
at the end when the GlobalCtxt is about to be destroyed.
