2020-03-26Rename asm! to llvm_asm!Amanieu d'Antras-23/+23
asm! is left as a wrapper around llvm_asm! to maintain compatibility.
2020-03-26create a tracking issue and link to itNiko Matsakis-2/+2
2020-03-26introduce `negative_impls` feature gate and documentNiko Matsakis-1/+120
They used to be covered by `optin_builtin_traits` but negative impls are now applicable to all traits, not just auto traits. This also adds docs in the unstable book for the current state of auto traits.

r=Dylan-DPC Fix sequence of Type and Trait in optin-builtin-traits in Unstable Book A simple fix in docs - the sequence of words in basic example of negative trait implementation was reversed.

2020-03-16Rollup merge of #70014 - TimotheeGerber:small-fix-rustdoc-book, r=Dylan-DPCDylan DPC-7/+7
Small fixes in rustdoc book I read the `rustdoc` book today and noticed some small typos/problems. Mainly: - `# fn foo() {}` was displayed when not needed because fenced block code type was `text` instead of `rust`; - two path separators were missing and some Windows-style separators were not consistent with the rest of them (mainly Linux-style). Here are my proposed fixes. It is my first PR for the rust project. Don't hesitate to tell me if I am doing it wrong or if you need anything else. Have a nice day!

2020-03-13Auto merge of #67502 - Mark-Simulacrum:opt-catch, r=Mark-Simulacrumbors-20/+3
Optimize catch_unwind to match C++ try/catch This refactors the implementation of catching unwinds to allow LLVM to inline the "try" closure directly into the happy path, avoiding indirection. This means that the catch_unwind implementation is (after this PR) zero-cost unless a panic is thrown. https://rust.godbolt.org/z/cZcUSB is an example of the current codegen in a simple case. Notably, the codegen is *exactly the same* if `-Cpanic=abort` is passed, which is clearly not great. This PR, on the other hand, generates the following assembly: ```asm # -Cpanic=unwind: push rbx mov ebx,0x2a call QWORD PTR [rip+0x1c53c] # <happy> mov eax,ebx pop rbx ret mov rdi,rax call QWORD PTR [rip+0x1c537] # cleanup function call call QWORD PTR [rip+0x1c539] # <unfortunate> mov ebx,0xd mov eax,ebx pop rbx ret # -Cpanic=abort: push rax call QWORD PTR [rip+0x20a1] # <happy> mov eax,0x2a pop rcx ret ``` Fixes #64224, and resolves #64222.

Rename rustc guide This is in preparation for https://github.com/rust-lang/rustc-guide/issues/470 Needs to be merged after we actually rename the guide. Have used this to rename: `git grep -l 'rustc_guide' | xargs sed -i 's/rustc_guide/rustc_dev_guide/g'` `git grep -l 'rustc-guide' | xargs sed -i 's/rustc-guide/rustc-dev-guide/g'` `git grep -l 'rustc guide' | xargs sed -i 's/rustc guide/rustc dev guide/g'`

2020-03-10Rollup merge of #69514 - GuillaumeGomez:remove-spotlight, r=kinnisonMazdak Farrokhzad-51/+0
Remove spotlight I had a few comments saying that this feature was at best misunderstood or not even used so I decided to organize a poll about on [twitter](https://twitter.com/imperioworld_/status/1232769353503956994). After 87 votes, the result is very clear: it's not useful. Considering the amount of code we have just to run it, I think it's definitely worth it to remove it. r? @kinnison cc @ollie27

2020-02-16Auto merge of #67885 - tobithiel:fix_group_lint_allow_override, ↵bors-0/+20
r=Mark-Simulacrum rustc_session: allow overriding lint level of individual lints from a group Fixes #58211 and fixes rust-lang/rust-clippy#4778 and fixes rust-lang/rust-clippy#4091 Instead of hard-coding the lint level preferences (from lowest to highest precedence: `lint::Allow -> lint::Warn -> lint::Deny -> lint::Forbid`), the position of the argument in the command line gets taken into account. Examples: 1. Passing `-D unused -A unused-variables` denies everything in the lint group `unused` **except** `unused-variables` which is explicitly allowed. 1. Passing `-A unused-variables -D unused` denies everything in the lint group `unused` **including** `unused-variables` since the allow is specified before the deny (and therefore overridden by the deny). This matches the behavior that is already being used when specifying `allow`/`deny` in the source code.
