2020-04-01Rollup merge of #70591 - cuviper:fulldeps-library-path, r=Mark-SimulacrumMazdak Farrokhzad-1/+10
Ensure LLVM is in the link path for "fulldeps" tests This is a follow-up to #70123, which added `llvm-config --libdir` to the `LIBRARY_PATH` for rustc tools. We need the same for "run-make-fulldeps" and "ui-fulldeps" tests which depend on compiler libraries, implicitly needing to link to `-lLLVM` as well.

2020-04-01Rollup merge of #70522 - rcoh:60762-raw-string-errors, r=petrochenkovMazdak Farrokhzad-74/+385
Improve error messages for raw strings (#60762) This diff improves error messages around raw strings in a few ways: - Catch extra trailing `#` in the parser. This can't be handled in the lexer because we could be in a macro that actually expects another # (see test) - Refactor & unify error handling in the lexer between ByteStrings and RawByteStrings - Detect potentially intended terminators (longest sequence of "#*" is suggested) Fixes #60762 cc @estebank who reviewed the original (abandoned) PR for the same ticket. r? @Centril
2020-04-01Rollup merge of #70511 - ecstatic-morse:mir-dataflow-graphviz, r=davidtwcoMazdak Farrokhzad-7/+30
Add `-Z dump-mir-dataflow` flag for dumping dataflow results visualization Previously, to visualize the results of a MIR dataflow pass, one had to add a `#[rustc_mir(borrowck_graphviz_postflow)]` attribute to functions of interest. However, there is no way to specify this attribute on closures and generators, so it was impossible to view results for these MIR bodies. This PR adds a flag, `-Z dump-mir-dataflow`, which will output the dataflow results for any functions specified in `-Z dump-mir` to the output directory specified by `-Z dump-mir-dir`. This behavior is modeled on the `-Z dump-mir-graphviz` flag.

2020-04-01Rename `modules_config` as `regular_config`.Nicholas Nethercote-4/+4
That way it matches `ModuleKind::Regular`.
2020-04-01Improve `ModuleConfig` initialization.Nicholas Nethercote-152/+137
There are three `ModuleConfigs`, one for each `ModuleKind`. The code to initialized them is spaghetti imperative code that sets each field to a default value and then modifies many fields in complicated ways. This makes it very hard to tell what value ends up in each field in each config. For example, the `modules_config.emit_pre_lto_bc` field is set twice, which means it can be set to true and then incorrectly set back to false. (This probably hasn't been noticed because it happens in a very obscure case.) This commit changes the code to a declarative style in which `ModuleConfig::new` initializes all fields and then they are never changed again. This is slightly more concise and much easier to read. (And it fixes the abovementioned `emit_pre_lto_bc` error as well.)

2020-04-01Remove some dead code.Nicholas Nethercote-7/+0
The condition checks if `sess.opts.output_types` doesn't contain `OutputType::Assembly` within a match arm that is only reached if `sess.opts.output_types` contains `OutputType::Assembly`.
2020-04-01Auto merge of #70414 - lopsided98:armv6-gcc-8, r=pietroalbinibors-743/+1035
Upgrade GCC to 8.3.0, glibc to 2.17.0 and crosstool-ng to 1.24.0 for dist-arm-linux and dist-armhf-linux Attempt to fix #69420 in the same manner as #65302 did for armv7l. I have tested that this eliminates the segfault while building a `hello_world` package on `arm-unknown-linux-gnueabihf`. I have not been able to test whether the bug exists for `arm-unknown-linux-gnueabi` as well, but I suspect it does, so I upgraded the toolchain for that platform as well.

2020-04-01Rollup merge of #70632 - tspiteri:vec-new, r=sfacklerDylan DPC-0/+6
expand vec![] to Vec::new() The current expansion of `vec![]` calls `into_vec` on a boxed slice, which results in longer IR, and even after optimization, some unwinding artifacts are still present in the IR. This PR uses `Vec::new()` for `vec![]`. This also allows `vec![]` to be used in const expressions.

2020-04-01Rollup merge of #68770 - ssomers:btree_drain_filter, r=AmanieuDylan DPC-14/+671
BTreeMap/BTreeSet: implement drain_filter Provide an implementation of drain_filter for BTreeMap and BTreeSet. Should be optimal when the predicate picks only elements in leaf nodes with at least MIN_LEN remaining elements, which is a common case, at least when draining only a fraction of the map/set, and also when the predicate picks elements stored in internal nodes where the right subtree can easily let go of a replacement element. The first commit adds benchmarks with an external, naive implementation. to compare how much this claimed optimality-in-some-cases is actually worth.

2020-03-31ci: disable cancel-outdated-builds for the try branchPietro Albini-0/+1
While for auto, try and PR builds we only want the latest commit to be tested, that's not true for try builds: each commit pushed to the branch is a different PR being tested, and we want multiple PRs to be tested in parallel if there is enough demand. Fixes #70569
