2020-08-08Eliminate the `SessionGlobals` from `librustc_ast`.Nicholas Nethercote-8/+5
By moving `{known,used}_attrs` from `SessionGlobals` to `Session`. This means they are accessed via the `Session`, rather than via TLS. A few `Attr` methods and `librustc_ast` functions are now methods of `Session`. All of this required passing a `Session` to lots of functions that didn't already have one. Some of these functions also had arguments removed, because those arguments could be accessed directly via the `Session` argument. `contains_feature_attr()` was dead, and is removed. Some functions were moved from `librustc_ast` elsewhere because they now need to access `Session`, which isn't available in that crate. - `entry_point_type()` --> `librustc_builtin_macros` - `global_allocator_spans()` --> `librustc_metadata` - `is_proc_macro_attr()` --> `Session`

This should not be a change in behavior.

2020-07-15Add and use more static symbols.Nicholas Nethercote-1/+1
Note that the output of `unpretty-debug.stdout` has changed. In that test the hash values are normalized from a symbol numbers to small numbers like "0#0" and "0#1". The increase in the number of static symbols must have caused the original numbers to contain more digits, resulting in different pretty-printing prior to normalization.

2020-02-20Auto merge of #69072 - ecstatic-morse:associated-items, r=petrochenkovbors-2/+2
O(log n) lookup of associated items by name Resolves #68957, in which compile time is quadratic in the number of associated items. This PR makes name lookup use binary search instead of a linear scan to improve its asymptotic performance. As a result, the pathological case from that issue now runs in 8 seconds on my local machine, as opposed to many minutes on the current stable. Currently, method resolution must do a linear scan through all associated items of a type to find one with a certain name. This PR changes the result of the `associated_items` query to a data structure that preserves the definition order of associated items (which is used, e.g., for the layout of trait object vtables) while adding an index of those items sorted by (unhygienic) name. When doing name lookup, we first find all items with the same `Symbol` using binary search, then run hygienic comparison to find the one we are looking for. Ideally, this would be implemented using an insertion-order preserving, hash-based multi-map, but one is not readily available. Someone who is more familiar with identifier hygiene could probably make this better by auditing the uses of the `AssociatedItems` interface. My goal was to preserve the current behavior exactly, even if it seemed strange (I left at least one FIXME to this effect). For example, some places use comparison with `ident.modern()` and some places use `tcx.hygienic_eq` which requires the `DefId` of the containing `impl`. I don't know whether those approaches are equivalent or which one should be preferred.
