- invert pre/code which was an invalid combination, that works fine in practice - remove unneeded code wrapper for graphs

…(rather than silently enabling them)

…tgross35,jhpratt [cfg_match] Document the use of expressions. cc rust-lang#115585 Adds documentation to this new feature introduced in rust-lang#133720.

…d-in-new-solver, r=lcnr Do not consider child bound assumptions for rigid alias r? lcnr See first commit for the important details. For second commit, I also stacked a somewhat opinionated name change, though I can separate that if needed. Fixes rust-lang/trait-system-refactor-initiative#149

Rename `Piece::String` to `Piece::Lit` This renames Piece::String to Piece::Lit to avoid shadowing std::string::String and removes "pub use Piece::*;".

…=matthewjasper Add mermaid graphs of NLL regions and SCCs to polonius MIR dump This PR expands the polonius MIR dump again with a couple of mermaid charts ported from the graphviz version: - the NLL region graph - and the NLL SCCs I still have done zero visual design on this until now, but [here's](https://gistpreview.github.io/?fbbf900fed2ad21108c7ca0353456398) how it looks (i.e. still bad) just to give an idea of the result. r? `````@matthewjasper````` (feel free to reassign) or anyone

…check-not-add, r=workingjubilee ABI-required target features: warn when they are missing in base CPU Part of rust-lang#135408: instead of adding ABI-required features to the target we build for LLVM, check that they are already there. Crucially we check this after applying `-Ctarget-cpu` and `-Ctarget-feature`, by reading `sess.unstable_target_features`. This means we can tweak the ABI target feature check without changing the behavior for any existing user; they will get warnings but the target features behave as before. The test changes here show that we are un-doing the "add all required target features" part. Without the full rust-lang#135408, there is no way to take a way an ABI-required target feature with `-Ctarget-cpu`, so we cannot yet test that part. Cc ``@workingjubilee``
