I'm one of the rare cases that does have uv, but doesn't have python installed globally
add a link to the issue fix test stderr
Tune the build configuration for loongarch64-linux targets to speed up rustc. Changes include: - Enable jemalloc and rust thin-lto. - Set codegen-units=1 and disable debug assertions. These changes reduce rustc-perf compile time by ~17%.
Move the query list into a new `rustc_middle::queries` module This moves the query list from `rustc_middle::query` into a new `rustc_middle::queries` module. This splits up the use of the query system from the remaining implementation of it in `rustc_middle::query`, which conceptually belong to `rustc_query_system`. The goal is to let rustc crates define queries with their own `queries` module, and this makes `rustc_middle` also fit this pattern. The inner `queries` module used by the macros are renamed to `query_info`, so it doesn't conflict with the new outer name.
ci: Optimize loongarch64-linux dist builders Tune the build configuration for loongarch64-linux targets to speed up rustc. Changes include: - Enable jemalloc and rust thin-lto. - Set codegen-units=1. These changes reduce rustc-perf compile time by ~17%.
Add uv to the list of possible python runners Fixes the unlikely case that one has uv, but not python, globally installed (It's me, I'm the unlikely case)
… r=jdonszelmann Convert to inline diagnostics in `rustc_interface` For rust-lang#151366 (comment)
…, r=nnethercote Avoid semicolon suggestion when tail expr is error Fixes rust-lang#151610 When the tail expression is Err due to recovery, HIR constructs `StmtKind::Semi(Err(..))`. The suggestion path then uses `stmt.span.with_lo(tail_expr.span.hi())` to target the semicolon, but `stmt.span == tail_expr.span` so the derived span is empty/invalid.
