2019-08-17Rollup merge of #63642 - eddyb:wrap-it-up, r=rkruppe,Mark-SimulacrumMazdak Farrokhzad-6/+6
Rename overflowing_{add,sub,mul} intrinsics to wrapping_{add,sub,mul}. These confused @Gankra, and then, also me, especially since `overflowing_*` *methods* also exist, but they map to `*_with_overflow` intrinsics! r? @oli-obk / @nikomatsakis cc @Mark-Simulacrum (on the rustbuild workaround)

2019-07-18Auto merge of #61749 - davidtwco:rfc-2203-const-array-repeat-exprs, r=eddybbors-78/+111
rustc/rustc_mir: Implement RFC 2203. This PR implements RFC 2203, allowing constants in array repeat expressions. Part of #49147. r? @eddyb
2019-07-16Auto merge of #62322 - wesleywiser:promoted_query, r=oli-obkbors-0/+7
Add a query to get the `promoted`s for a `mir::Body` This is a builidng block toward removing a lot of duplicated code between miri and the cosnt-propagator pass. See this thread for more info: https://rust-lang.zulipchat.com/#narrow/stream/189540-t-compiler.2Fwg-mir-opt/topic/Using.20.60InterpCx.60.20more/near/169030661 r? @spastorino but feel free to hand it off to somebody else

2019-07-10Rollup merge of #62275 - eddyb:const-drop-replace, r=pnkfelixMazdak Farrokhzad-3/+20
rustc_mir: treat DropAndReplace as Drop + Assign in qualify_consts. This slipped through the cracks and never got implemented (thankfully that just meant it was overly conservative and didn't allow assignments that don't *actually* drop the previous value). Fixes #62273. r? @oli-obk
2019-07-07syntax: Add feature gate.David Wood-1/+1
This commit adds a `const_in_array_repeat_expressions` feature gate and only create `Candidate::Repeat` if it is enabled.
2019-07-07rustc/rustc_mir: Implement RFC 2203.David Wood-78/+111
This commit implements RFC 2203, allowing constants in array repeat expressions. Firstly, the check that the array repeat expression implements `Copy` is removed and re-implemented in `rustc_mir::borrow_check::nll::type_check` by emitting an error when the MIR contains a `Operand::Move` and the type does not implement `Copy`. Next, the `qualify_consts` pass is modified to construct a `Candidate::Repeat` when it would be correct to promote a array repeat expression. Finally, the `promote_consts` pass is modified to promote the candidates previously identified.
