rustc's startup has several layers, including:
- `interface::run_compiler` passes a closure, `f`, to
`run_in_thread_pool_with_globals`, which creates a thread pool, sets
up session globals, and passes `f` to `create_compiler_and_run`.
- `create_compiler_and_run` creates a `Session`, a `Compiler`, sets the
source map, and calls `f`.
rustdoc is a bit different.
- `main_args` calls `main_options` via
`run_in_thread_pool_with_globals`, which (again) creates a thread pool
(hardcoded to a single thread!) and sets up session globals.
- `main_options` has four different paths.
- The second one calls `interface::run_compiler`, which redoes the
`run_in_thread_pool_with_globals`! This is bad.
- The fourth one calls `interface::create_compiler_and_run`, which is
reasonable.
- The first and third ones don't do anything of note involving the
above functions, except for some symbol interning which requires
session globals.
In other words, rustdoc calls into `rustc_interface` at three different
levels. It's a bit confused, and feels like code where functionality has
been added by different people at different times without fully
understanding how the globally accessible stuff is set up.
This commit tidies things up. It removes the
`run_in_thread_pool_with_globals` call in `main_args`, and adjust the
four paths in `main_options` as follows.
- `markdown::test` calls `test::test_main`, which provides its own
parallelism and so doesn't need a thread pool. It had one small use of
symbol interning, which required session globals, but the commit
removes this.
- `doctest::run` already calls `interface::run_compiler`, so it doesn't
need further adjustment.
- `markdown::render` is simple but needs session globals for interning
(which can't easily be removed), so it's now wrapped in
`create_session_globals_then`.
- The fourth path now uses `interface::run_compiler`, which is
equivalent to the old `run_in_thread_pool_with_globals` +
`create_compiler_and_run` pairing.
There is no longer any need for them to be separate.
It has a single call site, and removing it slightly improves the confusing tangle of nested closures present at startup.
It has a single call site.
This avoids the need for a degenerate `Lrc::get_mut` call.

…holk Make `dyn*` casts into a coercion, allow `dyn*` upcasting I know that `dyn*` is likely not going to be a feature exposed to surface Rust, but this makes it slightly more ergonomic to write tests for these types anyways. ... and this was just fun to implement anyways. 1. Make `dyn*` into a coercion instead of a cast 2. Enable `dyn*` upcasting since we basically get it for free 3. Simplify some of the cast checking code since we're using the coercion path now r? `@eholk` but feel free to reassign cc `@nikomatsakis` and `@tmandry` who might care about making `dyn*` casts into a coercion
Clean up rustdoc startup Startup is pretty hairy, in both rustdoc and rustc. The first commit here improves the rustdoc situation quite a bit. The remaining commits are smaller but also help. Best reviewed one commit at a time. r? ````@jyn514````
Use semaphores for thread parking on Apple platforms Currently we use a mutex-condvar pair for thread parking on Apple systems. Unfortunately, `pthread_cond_timedwait` uses the real-time clock for measuring time, which causes problems when the system time changes. The parking implementation in this PR uses a semaphore instead, which measures monotonic time by default, avoiding these issues. As a further benefit, this has the potential to improve performance a bit, since `unpark` does not need to wait for a lock to be released. Since the Mach semaphores are poorly documented (I could not find availability or stability guarantees for instance), this uses a [dispatch semaphore](https://developer.apple.com/documentation/dispatch/dispatch_semaphore?language=objc) instead. While it adds a layer of indirection (it uses Mach semaphores internally), the overhead is probably negligible. Tested on macOS 12.5. r? ````@thomcc````
