2020-08-02Auto merge of #74826 - matklad:mbe-fragment, r=petrochenkovbors-339/+319
Introduce NonterminalKind for more type-safe mbe parsing It encapsulate the (part of) the interface between the parser and macro by example (macro_rules) parser. The second bit is somewhat more general `parse_ast_fragment`, which is the reason why we keep some `parse_xxx` functions as public.

Fix ICEs with `@ ..` binding This reverts #74557 and introduces an alternative fix while ensuring that #74954 is not broken. The diagnostics are verbose though, it fixes three related issues. cc #74954, #74539, and #74702
2020-08-03Rollup merge of #75057 - Mark-Simulacrum:avoid-long-print, r=alexcrichtonYuki Okushi-1/+3
Avoid dumping rustc invocations to stdout These are quite long, usually, and in most cases not interesting. On smaller terminals they can take up more than a full page of output, hiding the error diagnostics emitted.

Rename rustc_middle::cstore::DepKind to CrateDepKind It is ambiguous with DepGraph's own DepKind.

Deduplicate `::` -> `:` typo errors Deduplicate errors caused by the same type ascription typo, including ones suggested during parsing that would get reported again during resolve. Fix #70382.

2020-08-01Auto merge of #74726 - oli-obk:tracing, r=Mark-Simulacrumbors-44/+63
Move from `log` to `tracing` The only visible change is that we now get timestamps in our logs: ``` Jul 24 18:41:01.065 TRACE rustc_mir::transform::const_prop: skipping replace of Rvalue::Use(const () because it is already a const Jul 24 18:41:01.065 TRACE rustc_mir::transform::const_prop: propagated into _2 Jul 24 18:41:01.065 TRACE rustc_mir::transform::const_prop: visit_constant: const () ``` This PR was explicitly designed to be as low-impact as possible. We can now move to using the name `tracing` insteads of `log` on a crate-by-crate basis and use any of the other tracing features where desirable. As far as I can tell this will allow tools to seamlessly keep working (since they are using `rustc_driver::init_log...`). This is the first half of step 1 of the accepted `tracing` MCP (https://github.com/rust-lang/compiler-team/issues/331)

[mir] Special treatment for dereferencing a borrow to a static definition Fix #70584. As suggested by @oli-obk in this [comment](https://github.com/rust-lang/rust/issues/70584#issuecomment-626009260), one can chase the definition of the local variable being de-referenced and check if it is a true static variable. If that is the case, `validate_place` will admit the promotion. This is my first time to contribute to `rustc`, and I have two questions. 1. A generalization to some extent is applied to decide if the promotion is possible in the static context. In case that there are more projection operations preceding the de-referencing, `validate_place` recursively decent into inner projection operations. I have put thoughts into its correctness but I am not totally sure about it. 2. I have a hard time to find a good place for the test case. This patch has to do with MIR, but this test case would look out of place compared to other tests in `src/test/ui/mir` or `src/test/ui/borrowck` because it does not generate errors while others do. It is tentatively placed in `src/test/ui/statics` for now. Thank you for any comments and suggestions!

davidtwco:issue-74636-polymorphized-closures-inherited-params, r=oli-obk mir: add `used_generic_parameters_needs_subst` Fixes #74636. This PR adds a `used_generic_parameters_needs_subst` helper function which checks whether a type needs substitution, but only for parameters that the `unused_generic_params` query considers used. This is used in the MIR interpreter to make the check for some pointer casts and for reflection intrinsics more precise. I've opened this as a draft PR because this might not be the approach we want to fix this issue and we have to decide what to do about the reflection case. r? @eddyb cc @lcnr @wesleywiser

Fix Const-Generic Cycle ICE #74199 This PR intends to fix the bug in Issue #74199 by following the suggestion provided of ignoring the error that causes the ICE. This does not fix the underlying cycle detection issue, but fixes the ICE. Also adds a test to check that it doesn't causes an ICE but returns a valid error for now. r? @lcnr Edit: Also it's funny how this PR number is an anagram of the issue number
