It doesn't seem like local interners are effective in keeping memory usage down. Is there some other reason to have them? cc @rust-lang/compiler |

Nominating for discussion at a @rust-lang/compiler meeting -- afaik, the whole For a decision this major, though, it seems like it would behoove us to gather more data than just perf. @Zoxc do you think you could measure bootstrap memory usage for stage2 or something like that? i'm not sure what's the easiest way to do that -- perhaps |

With some more options enabled (debug-assertions, debuginfo, experimental-parallel-queries) peak memory usage rises to 4.25 GB giving a 3% regression. |

Unify all uses of 'gcx and 'tcx. This is made possible by @Zoxc landing #57214 (see #57214 (comment) for the decision). A bit of context for the approach: just like #61722, this is *not* how I originally intended to go about this, but @Zoxc and my own experimentation independently resulted in the same conclusion: The interim alias `type TyCx<'tcx> = TyCtxt<'tcx, 'tcx>;` attempt required more work (adding `use`s), even only for handling the `TyCtxt<'tcx, 'tcx>` case and not the general `TyCtxt<'gcx, 'tcx>` one. What this PR is based on is the realization that `'gcx` is a special-enough name that it can be replaced, without caring for context, with `'tcx`, and then repetitions of the name `'tcx` be compacted away. After that, only a small number of error categories remained, each category easily dealt with with either more mass replacements (e.g. `TyCtxt<'tcx, '_>` -> `TyCtxt<'tcx>`) or by hand. For the `rustfmt` commit, I used rust-lang/rustfmt#1324 (comment), and manually filtered out some noise, like in #61735 and #61722, and like the latter, there was also a weird bug to work around. It should be reviewed separately, and dropped if unwanted (in this PR it's pretty significant). cc @rust-lang/compiler r? @nikomatsakis
