2019-09-08Rollup merge of #64255 - varkor:bool-to-option, r=CentrilMazdak Farrokhzad-1/+71
Add methods for converting `bool` to `Option<T>` This provides a reference implementation for https://github.com/rust-lang/rfcs/pull/2757.
2019-09-08Rollup merge of #64229 - kawa-yoiko:unreachable-call-lint, r=estebankMazdak Farrokhzad-13/+15
Reduce span to function name in unreachable calls As title suggests, this might close #64103. Refer to the updated tests for expected output. There is potential to further improve usability. In particular, is it favourable that the exact diverging expression/statement be pointed out (not only in this case, but for all unreachable code)? Certainly that would deserve another issue, but I'm interested in the opinions.
2019-09-08Rollup merge of #64177 - petrochenkov:curmod, r=matthewjasperMazdak Farrokhzad-9/+24
resolve: Do not afraid to set current module to enums and traits After https://github.com/rust-lang/rust/pull/63535/commits/cfbb60bf6d83fbcfcca1f2919131aa39fb997b53 it's ok. This is likely required for https://github.com/rust-lang/rust/pull/63468 to work correctly, because that PR starts resolving attributes on enum variants. r? @matthewjasper @c410-f3r
2019-09-08Rollup merge of #64066 - petrochenkov:softstab, r=matthewjasperMazdak Farrokhzad-28/+67
Support "soft" feature-gating using a lint Use it for feature-gating `#[bench]`. Closes https://github.com/rust-lang/rust/issues/63798.
2019-09-08Rollup merge of #64052 - ranweiler:debuginfo-boxed-struct-64050, r=alexcrichtonMazdak Farrokhzad-8/+8
Rename test locals to work around LLDB bug LLDB's expression parser can't unambiguously resolve local variables in some cases, as described in #47938. Work around this by using names that don't shadow direct submodules of `core`. Closes #64050.

2019-09-07Rollup merge of #64258 - smaeul:patch/arm-tests, r=Mark-SimulacrumMazdak Farrokhzad-3/+7
compiletest: Match suffixed environments This fixes a case where an `ignore-musl` test was not ignored on `armv7-unknown-linux-musleabihf` because the environment did not exactly match. Only enforce that the environment starts with the argument to `ignore-`.

2019-09-07Rollup merge of #64139 - Mark-Simulacrum:strip-legacy-proc-macro, r=petrochenkovMazdak Farrokhzad-489/+176
Migrate internal diagnostic registration to macro_rules Review is best done commit-by-commit. Fixes #64132.
2019-09-07Rollup merge of #64098 - Mark-Simulacrum:always-warn, r=alexcrichtonMazdak Farrokhzad-10/+12
Ensure edition lints and internal lints are enabled with deny-warnings=false Previously we only passed the deny command line flags if deny-warnings was enabled, but now we either pass -W... or -D... for each of the flags as appropriate. This is also a breaking change to x.py as it changes `--warnings=allow` to `--warnings=warn` which is what that flag actually did; we don't have an allow warnings mode.
2019-09-07Rollup merge of #64023 - tmandry:libstd-fuchsia-fixes, r=cramertjMazdak Farrokhzad-27/+76
libstd fuchsia fixes This fixes two bugs in libstd on Fuchsia: - `zx_time_t` was changed to an `i64`, but this never made it into libstd - When spawning processes where any of the stdio were null, libstd attempts to open `/dev/null`, which doesn't exist on Fuchsia r? @cramertj

2019-09-07Rollup merge of #64243 - petrochenkov:cmdattr, r=alexcrichtonMazdak Farrokhzad-48/+48
Move injection of attributes from command line to `libsyntax_ext` Just a tiny bit of code generation that wasn't moved into `libsyntax_ext` in https://github.com/rust-lang/rust/pull/62771.

2019-09-07Rollup merge of #64240 - maurer:include-compiler-rt, r=alexcrichtonMazdak Farrokhzad-0/+1
Include compiler-rt in the source tarball In #60981 we switched to using src/llvm-project/compiler-rt inside compiler-builtins rather than a separate copy of it. In order to have the "c" feature turn on in builds from the source tarball, we need to include that path in its creation. fixes #64239

2019-09-07Rollup merge of #64231 - matthewjasper:move-ast-cfg, r=CentrilMazdak Farrokhzad-43/+32

2019-09-07Rollup merge of #64192 - estebank:turbofish-madness, r=petrochenkovMazdak Farrokhzad-138/+37
Bail out when encountering likely missing turbofish in parser When encountering a likely intended turbofish without `::`, bubble up the diagnostic instead of emitting it to allow the parser to recover more gracefully and avoid uneccessary type errors that are likely to be wrong. Fix #61329.
2019-09-07Rollup merge of #64149 - eddyb:llvm-var-names, r=rkruppeMazdak Farrokhzad-13/+73
rustc_codegen_llvm: give names to non-alloca variable values. These names only matter when looking at LLVM IR, but they can help. When one value is used for multiple variables, I decided to combine the names. I chose `,` as a separator but maybe `=` or ` ` (space) are more appropriate. (LLVM names can contain any characters - if necessary they end up having quotes) As an example, this function: ```rust #[no_mangle] pub fn test(a: u32, b: u32) -> u32 { let c = a + b; let d = c; let e = d * a; e } ``` Used to produce this LLVM IR: ```llvm define i32 @test(i32 %a, i32 %b) unnamed_addr #0 { start: %0 = add i32 %a, %b %1 = mul i32 %0, %a ret i32 %1 } ``` But after this PR you get this: ```llvm define i32 @test(i32 %a, i32 %b) unnamed_addr #0 { start: %"c,d" = add i32 %a, %b %e = mul i32 %"c,d", %a ret i32 %e } ``` cc @nagisa @rkruppe
2019-09-07Rollup merge of #63927 - mark-i-m:filter-spurious, r=ehussMazdak Farrokhzad-34/+54
Filter linkcheck spurious failure r? @ehuss cc @spastorino Basically, we filter errors with messages containing "timed out"... a bit of a hack, but hopefully this will be functionality built into linkcheck soon.
2019-09-07Rollup merge of #63919 - matthewjasper:remove-gensymmed, r=petrochenkovMazdak Farrokhzad-439/+555
Use hygiene for AST passes AST passes are now able to have resolve consider their expansions as if they were opaque macros defined either in some module in the current crate, or a fake empty module with `#[no_implicit_prelude]`. * Add an ExpnKind for AST passes. * Remove gensyms in AST passes. * Remove gensyms in`#[test]`, `#[bench]` and `#[test_case]`. * Allow opaque macros to define tests. * Move tests for unit tests to their own directory. * Remove `Ident::{gensym, is_gensymed}` - `Ident::gensym_if_underscore` still exists. cc #60869, #61019 r? @petrochenkov
