Use `summary_opts()` in another spot I added `summary_opts()` before I cut the branch for #77686 (2 months ago!), so this "slipped through the cracks".
2020-12-07Auto merge of #79653 - tmiasko:naked-functions, r=Amanieubors-139/+773
Validate naked functions definitions Validate that naked functions are defined in terms of a single inline assembly block that uses only `const` and `sym` operands and has `noreturn` option. Implemented as future incompatibility lint with intention to migrate it into hard error. When it becomes a hard error it will ensure that naked functions are either unsafe or contain an unsafe block around the inline assembly. It will guarantee that naked functions do not reference functions parameters (obsoleting part of existing checks from #79411). It will limit the definitions of naked functions to what can be reliably supported. It will also reject naked functions implemented using legacy LLVM style assembly since it cannot satisfy those conditions. https://github.com/rust-lang/rfcs/pull/2774 https://github.com/rust-lang/rfcs/pull/2972

2020-12-07Auto merge of #79751 - aDotInTheVoid:json-true-idx, r=jyn514bors-41/+249
Rustdoc: Use correct def_id for doctree::Import The default overwrites the crate root, which crashes rustdoc-json. While investigating this, It turns out somehow, some items are being documented twice. I'm not sure how this is happening but for now, we just make sure they were the same if they have the same id.

2020-12-06Auto merge of #6421 - xFrednet:4176-unreadable-literal-lint-fractal-option, ↵bors-37/+118
r=Manishearth Added a lint-fraction-readability flag to the configuration This adds an option to disable the `unreadable_literal` lint for floats with a longer fraction. This allows users to write `0.100200300` without getting a warning. Fixes #4176 I have some open questions about this PR: 1. I've named the option `lint-fraction-readability` is this a good name or should I rename it to something else? 2. What should the default configuration value be? * The current default value is `true` as this was also the previous default. 3. Do I have to document this new option somewhere else or will it be extracted from the code comment? 4. The current fix option will also rewrite the fraction if the integer part violates the `unreadable_literal` lint it would otherwise also trigger the `inconsistent_digit_grouping` lint. Is this also okay? * `1.100200300` will be unaffected by the fix function * `100200300.100200300` will be effected and fixed to `100_200_300.100_200_300` --- The project needed some getting used to but I'm happy with the result. A big thank you to `@flip1995` for giving me some pointers for this implementation and to everyone for the great introduction documentation! --- changelog: Added the `unreadable-literal-lint-fractions` configuration to disable the `unreadable_literal` lint for fractions

2020-12-06Auto merge of #79650 - the8472:fix-take, r=dtolnaybors-16/+54
Fix incorrect io::Take's limit resulting from io::copy specialization The specialization introduced in #75272 fails to update `io::Take` wrappers after performing the copy syscalls which bypass those wrappers. The buffer flushing before the copy does update them correctly, but the bytes copied after the initial flush weren't subtracted. The fix is to subtract the bytes copied from each `Take` in the chain of wrappers, even when an error occurs during the syscall loop. To do so the `CopyResult` enum now has to carry the bytes copied so far in the error case.
2020-12-05Auto merge of #79697 - rylev:clearer-const-diagnostic, r=oli-obkbors-25/+25
A slightly clearer diagnostic when misusing const Fixes #79598 This produces the following diagnostic: "expected one of `>`, a const expression, lifetime, or type, found keyword `const`" Instead of the previous, more confusing: "expected one of `>`, const, lifetime, or type, found keyword `const`" This might not be completely clear as some users might not understand what a const expression is, but I do believe this is an improvement.

Fix src/test/ui/env-vars.rs on 128-core machines on Windows On Windows, the environment variable NUMBER_OF_PROCESSORS has special meaning. Unfortunately, you can get different answers, depending on whether you are enumerating all environment variables or querying a specific variable. This was causing the src/test/ui/env-vars.rs test to fail on machines with more than 64 processors when run on Windows.

check the recursion limit when finding a struct's tail fixes #79437 This does a `delay_span_bug` (via `ty_error_with_message`) rather than emit a new error message, under the assumption that there will be an error elsewhere (even if the type isn't infinitely recursive, just deeper than the recursion limit, this appears to be the case).
