2020-09-19Stop using the `const_eval` query for initializers of staticsOliver Scherer-2/+4
As a side effect, we now represent most promoteds as `ConstValue::Scalar` again. This is useful because all implict promoteds are just references anyway and most explicit promoteds are numeric arguments to `asm!` or SIMD instructions.
2020-09-18Auto merge of #72412 - VFLashM:issue-72408-nested-closures-exponential, ↵bors-19/+28
r=tmandry Issue 72408 nested closures exponential This fixes #72408. Nested closures were resulting in exponential compilation time. This PR is enhancing asymptotic complexity, but also increasing the constant, so I would love to see perf run results.
2020-09-17Better handling for exponential-sized types in misc placesValerii Lashmanov-19/+28
Mostly to fix ui/issues/issue-37311-type-length-limit/issue-37311.rs. Most parts of the compiler can handle deeply nested types with a lot of duplicates just fine, but some parts still attempt to naively traverse type tree. Before such problems were caught by type length limit check, but now these places will have to be changed to handle duplicated types gracefully.
2020-09-16Rollup merge of #76694 - wesleywiser:partitioning_cx_trait, r=davidtwcoDylan DPC-34/+38
Introduce a PartitioningCx struct This contains all the data used by the partitioning algorithm and allows that data to be used at each stage of the partitioning. This is useful for other approaches to partitioning which may want different pieces of the data available at each step. cc @rust-lang/wg-incr-comp

use sort_unstable to sort primitive types It's not important to retain original order if we have &[1, 1, 2, 3] for example. clippy::stable_sort_primitive

2020-09-02pretty: trim paths of unique symbolsDan Aloni-1/+2
If a symbol name can only be imported from one place for a type, and as long as it was not glob-imported anywhere in the current crate, we can trim its printed path and print only the name. This has wide implications on error messages with types, for example, shortening `std::vec::Vec` to just `Vec`, as long as there is no other `Vec` importable anywhere. This adds a new '-Z trim-diagnostic-paths=false' option to control this feature. On the good path, with no diagnosis printed, we should try to avoid issuing this query, so we need to prevent trimmed_def_paths query on several cases. This change also relies on a previous commit that differentiates between `Debug` and `Display` on various rustc types, where the latter is trimmed and presented to the user and the former is not.
2020-08-31Rollup merge of #76002 - richkadel:llvm-coverage-map-gen-6b.3, r=tmandryTyler Mandry-2/+2
Fix `-Z instrument-coverage` on MSVC Found that `-C link-dead-code` (which was enabled automatically under `-Z instrument-coverage`) was causing the linking error that resulted in segmentation faults in coverage instrumented binaries. Link dead code is now disabled under MSVC, allowing `-Z instrument-coverage` to be enabled under MSVC for the first time. More details are included in Issue #76038 . Note this PR makes it possible to support `Z instrument-coverage` but does not enable instrument coverage for MSVC in existing tests. It will be enabled in another PR to follow this one (both PRs coming from original PR #75828). r? @tmandry FYI: @wesleywiser

2020-08-30ty: remove obsolete printerDavid Wood-18/+10
This commit removes the obsolete printer and replaces all uses of it with `FmtPrinter`. Of the replaced uses, all but one use was in `debug!` logging, two cases were notable: - `MonoItem::to_string` is used in `-Z print-mono-items` and therefore affects the output of all codegen-units tests. - `DefPathBasedNames` was used in `librustc_codegen_llvm/type_of.rs` with `LLVMStructCreateNamed` and that'll now get different values, but this should result in no functional change.
