2022-02-17	Remove SimpleDefKind	Mark Rousskov	-2/+0

2022-02-09	Auto merge of #93741 - Mark-Simulacrum:global-job-id, r=cjgillot	bors	-0/+1
	Refactor query system to maintain a global job id counter This replaces the per-shard counters with a single global counter, simplifying the JobId struct down to just a u64 and removing the need to pipe a DepKind generic through a bunch of code. The performance implications on non-parallel compilers are likely minimal (this switches to `Cell<u64>` as the backing storage over a `u64`, but the latter was already inside a `RefCell` so it's not really a significance divergence). On parallel compilers, the cost of a single global u64 counter may be more significant: it adds a serialization point in theory. On the other hand, we can imagine changing the counter to have a thread-local component if it becomes worrisome or some similar structure. The new design is sufficiently simpler that it warrants the potential for slight changes down the line if/when we get parallel compilation to be more of a default. A u64 counter, instead of u32 (the old per-shard width), is chosen to avoid possibly overflowing it and causing problems; it is effectively impossible that we would overflow a u64 counter in this context.

2022-02-06	Delete query stats	Mark Rousskov	-3/+0
	These statistics are computable from the self-profile data and/or ad-hoc collectable as needed, and in the meantime contribute to rustc bootstrap times.
2022-02-01	add a rustc::query_stability lint	lcnr	-0/+1

2021-12-14	Remove `in_band_lifetimes` from `rustc_query_impl`	LegionMammal978	-1/+0
	See #91867 for more information.
2021-10-28	Revert "Add rustc lint, warning when iterating over hashmaps"	Mark Rousskov	-1/+0

2021-10-25	Avoid a branch on key being local for queries that use the same local and ↵	bjorn3	-1/+1
	extern providers
2021-10-25	Auto merge of #90210 - cjgillot:qarray2, r=Mark-Simulacrum	bors	-6/+11
	Build the query vtable directly. Continuation of https://github.com/rust-lang/rust/pull/89978. This shrinks the query interface and attempts to reduce the amount of function pointer calls.
2021-10-24	Rollup merge of #89558 - lcnr:query-stable-lint, r=estebank	Matthias Krüger	-0/+1

2021-02-20	Move print_query_stack to rustc_query_system.	Camille GILLOT	-1/+1

2021-02-20	Move report_cycle to rustc_query_system.	Camille GILLOT	-1/+1
	The call to `ty::print::with_forced_impl_filename_line` is done when constructing the description, at the construction of the QueryStackFrame.
2021-02-20	Move Query to rustc_query_system.	Camille GILLOT	-1/+0
	Rename it to QueryStackFrame and document a bit.
