2021-01-25Auto merge of #68828 - oli-obk:inline_cycle, r=wesleywiserbors-0/+194
Prevent query cycles in the MIR inliner r? `@eddyb` `@wesleywiser` cc `@rust-lang/wg-mir-opt` The general design is that we have a new query that is run on the `validated_mir` instead of on the `optimized_mir`. That query is forced before going into the optimization pipeline, so as to not try to read from a stolen MIR. The query should not be cached cross crate, as you should never call it for items from other crates. By its very design calls into other crates can never cause query cycles. This is a pessimistic approach to inlining, since we strictly have more calls in the `validated_mir` than we have in `optimized_mir`, but that's not a problem imo.

2021-01-24Rollup merge of #81310 - tmiasko:in-pattern, r=petrochenkovJonas Schievink-1/+40
Do not mark unit variants as used when in path pattern Record that we are processing a pattern so that code responsible for handling path resolution can correctly decide whether to mark it as used or not. Closes #76788.
2021-01-24Rollup merge of #81302 - LeSeulArtichaut:80777-trait-render, r=jyn514Jonas Schievink-30/+40
Fix rendering of stabilization version for trait implementors Rustdoc compares an item's stabilization version with its parent's to not render it if they are the same. Here, the implementor was compared with itself, resulting in the stabilization version never getting shown. This probably needs a test. Fixes #80777. r? `@jyn514`
2021-01-24Rollup merge of #81264 - Swatinem:doctest-run-directory, r=jyn514Jonas Schievink-0/+51

2021-01-24Rollup merge of #81259 - est31:cfg_version, r=petrochenkovJonas Schievink-30/+110
Replace version_check dependency with own version parsing code This gives compiler maintainers a better degree of control over how the version gets parsed and is a good way to ensure that there are no changes of behaviour in the future. Also, issue a warning if the version is invalid instead of erroring so that we stay forwards compatible with possible future changes of the versioning scheme. Last, this improves the present test a little. Fixes #79436 r? `@petrochenkov`
2021-01-24Rollup merge of #80855 - m-ou-se:assert-2021, r=petrochenkovJonas Schievink-0/+9
Expand assert!(expr, args..) to include $crate for hygiene on 2021. This makes `assert!(expr, args..)` properly hygienic in Rust 2021. This is part of rust-lang/rfcs#3007, see #80162. Before edition 2021, this was a breaking change, as `std::panic` and `core::panic` are different. In edition 2021 they will be identical, making it possible to apply proper hygiene here.

2021-01-24Auto merge of #80838 - nagisa:nagisa/stack-probe-type, r=cuviperbors-0/+1
Target stack-probe support configurable finely This adds capability to configure the target's stack probe support in a more precise manner than just on/off. In particular now we allow choosing between always inline-asm, always call or either one of those depending on the LLVM version. Note that this removes the ability to turn off the generation of the stack-probe attribute. This is valid to replace it with inline-asm for all targets because `probe-stack="inline-asm"` will not generate any machine code on targets that do not currently support stack probes. This makes support for stack probes on targets that don't have any right now automatic with LLVM upgrades in the future. (This is valid to do based on the fact that clang unconditionally sets this attribute when `-fstack-clash-protection` is used, AFAICT) cc #77885 r? `@cuviper`

Fix <unknown> queries and add more timing info to render_html Closes https://github.com/rust-lang/rust/issues/81251. ## Fix `<unknown>` queries This happened because `alloc_query_strings` was never called. ## Add more timing info to render_html This still has some issues I'm not sure how to work out: - `create_renderer` and `renderer_after_krate` aren't shown by default. I want something like `verbose_generic_activity_with_arg`, but it doesn't exist. I'm also not sure how to show activities that aren't on by default - I tried `-Z self-profile -Z self-profile-args=all`, but it didn't show up. r? `@wesleywiser`

2021-01-23Auto merge of #80579 - RalfJung:no-fallible-promotion, r=oli-obkbors-281/+238
avoid promoting division, modulo and indexing operations that could fail For division, `x / y` will still be promoted if `y` is a non-zero integer literal; however, `1/(1+1)` will not be promoted any more. While at it, also see if we can reject promoting floating-point arithmetic (which are [complicated](https://github.com/rust-lang/unsafe-code-guidelines/issues/237) so maybe we should not promote them). This will need a crater run to see if there's code out there that relies on these things being promoted. If we can land this, promoteds in `fn`/`const fn` cannot fail to evaluate any more, which should let us do some simplifications in codegen/Miri!
