…ir_build, r=JonathanBrouwer Convert to inline diagnostics in `rustc_mir_build` Part of rust-lang#151366. r? @JonathanBrouwer

…=oli-obk Dont strip const blocks in array lengths r? oli-obk mGCA now handles const blocks by *always* handling them during `lower_expr_to_const_arg_direct` instead of *sometimes* stripping them out at parse time. This is just generally a lot clearer/nicer but also means parsing isn't lossy which is just straight up wrong. We now use `MgcaDisambiguation::Direct` for const blocks because we "directly" represent a const block as `hir::ConstArgKind::Anon` :> The only time that an anon const for const generics uses `MgcaDisambiguation::AnonConst` is for unbraced literals. Once we properly support literals in `hir::ConstArgKind` (see rust-lang#152139 rust-lang#152001) then `MgcaDisambiguation` can be renamed to `AnonConstKind` with `TypeSystem` and `NonTypeSystem` variants. We can also get rid of `mgca_direct_lit_hack`. I expect this to be a very nice cleanup :) Fixes rust-lang/rustfmt#6788 The diff relating to passing spans around is to avoid a bunch of mGCA diagnostics changing from `const {}` to `{}`. I'm not entirely sure why this was happening. cc @rust-lang/rustfmt How do I run the tests in the rustfmt repo from here? `x test rustfmt` only seems to run like 100 tests and doesn't result in a `target/issue-6788.rs` getting created. I've verified locally that this formats correctly though
…=GuillaumeGomez Use relative paths for std links in rustc-docs Fixes rust-lang#151496 This adds `--extern-html-root-url` for each `STD_PUBLIC_CRATES` entry pointing to `../`, so that `rustc-docs` links to the locally installed `rust-docs` via relative paths. r? @GuillaumeGomez @rami3l

Finished benchmarking commit (c58d9f9): comparison URL. Overall result: ❌✅ regressions and improvements - please read the text belowOur benchmarks found a performance regression caused by this PR. Next Steps:
@rustbot label: +perf-regression Instruction countOur most reliable metric. Used to determine the overall result above. However, even this metric can be noisy.
Max RSS (memory usage)Results (primary -0.0%, secondary 1.0%)A less reliable metric. May be of interest, but not used to determine the overall result above.
CyclesResults (secondary -4.2%)A less reliable metric. May be of interest, but not used to determine the overall result above.
Binary sizeThis benchmark run did not return any relevant results for this metric. Bootstrap: 474.536s -> 475.659s (0.24%) |

Secondary benchmark improvements probably due to inline diagnostics again. |

Seems to be mostly explained by the inline diagnostics PRs. Some benchmarks don't show up but that's likely because together they are significant, but separately they are not |
