2019-04-16Auto merge of #59769 - RalfJung:compiletest-normalization, r=alexcrichtonbors-8/+89
compiletest normalization: preserve non-JSON lines such as ICEs Currently, every non-JSON line from stderr gets normalized away when compiletest normalizes the output. In particular, ICEs get normalized to the empty output. That does not seem desirable, so this changes normalization to preserve non-JSON lines instead. Also see https://github.com/laumann/compiletest-rs/issues/169: because of that bug, Miri currently *looks* green in the toolstate, but some tests ICE. That same bug is likely no longer present in latest compiletest because the error code gets checked separately, but it still seems like a good idea to also make sure that ICEs are considered stderr output: This change found an accidental user-visible `error!` in CTFE validation (fixed), and a non-deterministic panic when there are two `main` symbols (not fixed, no idea where this comes from). Both got missed before because non-JSON output got ignored.

rustdoc: use --static-root-path for settings.js At the time i was writing https://github.com/rust-lang/docs.rs/pull/332, i noticed that the `settings.js` file that was being loaded was not being loaded from the `--static-root-path`. This PR fixes that so that users on docs.rs can effectively cache this file.

2019-04-14Auto merge of #59335 - Aaron1011:fix/extern-priv-final, r=Aaron1011bors-1/+1
Properly parse '--extern-private' with name and path It turns out that https://github.com/rust-lang/rust/pull/57586 didn't properly parse `--extern-private name=path`. This PR properly implements the `--extern-private` option. I've added a new `extern-private` option to `compiletest`, which causes an `--extern-private` option to be passed to the compiler with the proper path.

Fix cross-crate visibility of fictive variant constructors After merging https://github.com/rust-lang/rust/pull/59376 I realized that the code in the decoder wasn't entirely correct - we "decoded" fictive variant constructors with their variant's visibility, which could be public, rather than demoted to `pub(crate)`. Fictive constructors are not directly usable in expression/patterns, but the effect still can be observed with imports. r? @davidtwco

2019-04-14Rollup merge of #59874 - michaelwoerister:pgo-updates-1, r=cramertjMazdak Farrokhzad-8/+4
Clean up handling of `-Z pgo-gen` commandline option. This PR adapts the `-Z pgo-gen` flag to how Clang and GCC handle the corresponding `-fprofile-generate` flag. In particular, the flag now optionally takes a directory to place the profiling data in and allows to omit the argument (instead of having to pass an empty string).
2019-04-14Rollup merge of #59812 - michaelwoerister:profile-gen-msvc-imp, r=alexcrichtonMazdak Farrokhzad-0/+12
Exclude profiler-generated symbols from MSVC __imp_-symbol workaround. LLVM's profiling instrumentation adds a few symbols that are used by the profiler runtime. Since these show up as globals in the LLVM IR, the compiler generates `dllimport`-related `__imp_` stubs for them. This can lead to linker errors because the instrumentation symbols have weak linkage or are in a comdat section, but the `__imp_` stubs aren't. Instead of trying to replicate the linkage/comdat setup for the stubs, this PR just excludes the profiler-related symbols from stub-generation since they aren't supposed to be referenced via `__declspec(dllimport)` anywhere anyway. r? @alexcrichton EDIT: I considered making this more general, i.e. inferring from the symbol name if it is a Rust symbol or not. But then I figured out that that would yield false negatives for `#[no_mangle]` et al, so I went with a blacklist approach.

2019-04-12Rollup merge of #59846 - euclio:not-a-module, r=davidtwcoMazdak Farrokhzad-50/+62
clarify what the item is in "not a module" error The motivation here was that I was trying to import an associated constant when I thought it was an enum variant, and got confused by this error. Ideally I would like to add a note saying that associated constants, types, and methods cannot be imported, but I'm not sure that the associated items for a `Def` can be checked at resolve time.

Remove check_match from const_eval This fixes #59378. It seems that the `check_match` may be unnecessary, so this removes it per instructions provided in the issue. I re-ran the tests for `librustc_mir` and everything seemed fine!
