Deprecate the asm! macro in favor of llvm_asm! Since we will be changing the syntax of `asm!` soon, deprecate it and encourage people to use `llvm_asm!` instead (which preserves the old syntax). This will avoid breakage when `asm!` is changed. RFC: https://github.com/rust-lang/rfcs/pull/2843

2020-04-19Auto merge of #70015 - jonas-schievink:gen-needs-drop, r=matthewjasperbors-13/+9
Make `needs_drop` less pessimistic on generators Generators only have non-trivial drop logic when they may store (in upvars or across yields) a type that does. This prevents generation of some unnecessary MIR in simple generators. There might be some impact on compile times, but this is probably limited in real-world applications. ~~This builds off of https://github.com/rust-lang/rust/pull/69814 since that contains some fixes that are made relevant by *this* PR (see https://github.com/rust-lang/rust/pull/69814#issuecomment-599147269).~~ (this has been merged)

2020-04-17Rollup merge of #69642 - ecstatic-morse:issue-69615, r=oli-obkDylan DPC-0/+28
Use query to determine whether function needs const checking Resolves #69615. The HIR const-checker was checking the `constness` of a function's `fn_sig` to determine whether a function needed const-checking. Now that const trait impls are a thing, this is no longer enough. All code should use the `is_const_fn_raw` query instead, which takes the constness of the impl block into account. r? @oli-obk

2020-04-17Auto merge of #71049 - eddyb:const-err, r=oli-obkbors-293/+47
Add `ConstKind::Error` and convert `ErrorHandled::Reported` to it. By replicating the `ty::Error` approach to encoding "an error has occurred", all of the mechanisms that skip redundant/downstream errors are engaged and help out (see the reduction in test output). This PR also adds `ErrorHandled::Linted` for the lint case because using `ErrorHandled::Reported` *without* having emitted an error that is *guaranteed* to stop compilation, is incorrect now. r? @oli-obk cc @rust-lang/wg-const-eval @varkor @yodaldevoid

2020-04-17Rollup merge of #71164 - RalfJung:uninit-not-undef, r=oli-obkDylan DPC-5/+115
reword Miri validity errors: undefined -> uninitialized I don't think we say "undefined value" or anything like that anywhere in the docs or so, but we do use the term "uninitialized memory", so I think we should do the same here. Longer-term, I think we should also internally rename "undef" to "uninit". r? @oli-obk
