Robert O'Callahan 0a64402dde Create a toplevel `ParallelDispatchThreadPool` and parallelize `keep_cache_t::scan_module()` with it 2026-02-17 03:24:51 +00:00
Robert O'Callahan 20189460bd Introduce `RmStats` struct to encapsulate removal statistics 
Turns out this is not strictly necessary for this PR but it's
still a good thing to do and makes it clearer that the stats
are not modified in a possibly racy way.

Robert O'Callahan b153fc2d16 Make `keep_cache_t` process all modules up-front instead of on-demand 
We will want to query `keep_cache` from parallel threads. If we compute
the results on-demand, that means we need synchronization for cache
access in those queries, which adds complexity and overhead. Instead, prefill
the cache with the status of all relevant modules. Note that this doesn't
actually do more work --- we always consult `keep_cache` for all cells of
all selected modules, so scanning all those cells and determining the kept
status of all dependency modules is always required.

Later in this PR we're going to parallelize `scan_module` itself, and that's also
much easier to do when no other parallel threads are running.

Robert O'Callahan ae569486a0 Work around `std::reverse` miscompilation with empty range 
This causes problems when compiling with fuzzing instrumenation enabled.
 2026-02-17 03:24:51 +00:00
Robert O'Callahan af3bb9751f Make `log_error()` work in a `Multithreaded` context. 
`log_error()` causes an exit so we don't have to try too hard here. The main
thing is to ensure that we normally are able to exit without causing a stack
overflow due to recursive asserts about not being in a `Multithreaded` context.
 2026-02-17 03:24:51 +00:00
Robert O'Callahan 577191e44d Add `IdString::unescape()` method 
We've already talked about adding this as an alternative to `log_id()`, and we'll
need it later in this PR.
