2020-03-24save/restore `pessimistic_yield` when entering bodiesNiko Matsakis-0/+2
This flag is used to make the execution order around `+=` operators pessimistic. Failure to save/restore the flag was causing independent async blocks to effect one another, leading to strange ICEs and failed assumptions.

The codegen implementation already works for this, so we're: * propagating track_caller attr from trait def to impl * relaxing errors * adding tests Approved in a recent lang team meeting: https://github.com/rust-lang/lang-team/blob/master/minutes/2020-01-09.md
2020-03-21Rollup merge of #69901 - RalfJung:rustc_layout, r=eddybDylan DPC-8/+21
add #[rustc_layout(debug)] @eddyb recently told me about the `#[rustc_layout]` attribute, and I think it would be very useful if it could be used to print all the layout information Rust has about a type. When working with layouts (e.g. in Miri), it is often not clear how certain surface language features get represented internally. I have some awful hacks locally to be able to dump this debug information; with this attribute I could get it on the playground which is so much better. :)

2020-03-18Rollup merge of #69920 - Centril:hir-cleanup, r=ZoxcMazdak Farrokhzad-28/+21
Remove some imports to the rustc crate - When we have `NestedVisitorMap::None`, we use `type Map = dyn intravisit::Map<'v>;` instead of the actual map. This doesn't actually result in dynamic dispatch (in the future we may want to use an associated type default to simplify the code). - Use `rustc_session::` imports instead of `rustc::{session, lint}`. r? @Zoxc

ast: `Mac`/`Macro` -> `MacCall` It's now obvious that these refer to macro calls rather than to macro definitions. It's also a single name instead of two different names in different places. `rustc_expand` usually calls macro calls in a wide sense (including attributes and derives) "macro invocations", but structures and variants renamed in this PR are only relevant to fn-like macros, so it's simpler and clearer to just call them calls. cc https://github.com/rust-lang/rust/pull/63586#discussion_r314232513 r? @eddyb

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.
