2019-10-14Rollup merge of #65340 - bjorn3:cg_ssa_refactor4, r=eddybTyler Mandry-0/+3
Several changes to the codegen backend organization * Split functions from values in cg_ssa `BackendTypes`. * Remove `is_const_integral` function from `ConstMethods`. * Actually register the invalid monomorphization of intrinsic long diagnostic and remove the `diagnostics` method from `CodegenBackends`, as it was unused. * Add cg_ssa and cg_utils provided methods to `default_provide`, so codegen backend don't have to do it themself.

2019-10-01Rollup merge of #64840 - michaelwoerister:self-profiling-raii-refactor, ↵Tyler Mandry-12/+12
r=wesleywiser SelfProfiler API refactoring and part one of event review This PR refactors the `SelfProfiler` a little bit so that most profiling methods are RAII-based. The codegen backend code already had something similar, this refactoring pulls this functionality up into `SelfProfiler` itself, for general use. The second commit of this PR is a review and update of the existing events we are already recording. Names have been made more consistent. CGU names have been removed from event names. They will be added back in when function parameter recording is implemented. There is still some work to be done for adding new events, especially around trait resolution and the incremental system. r? @wesleywiser

2019-09-25Rollup merge of #62975 - ljedrz:kill_off_hir_to_node_id, r=ZoxcMazdak Farrokhzad-7/+8
Almost fully deprecate hir::map::Map.hir_to_node_id - HirIdify `doctree::Module.id` - HirIdify `hir::Crate.modules` - introduce a `HirId` to `DefIndex` map in `map::Definitions` The only last uses of `hir::map::Map.hir_to_node_id` in the compiler are: - for the purposes of `driver::pretty` (in `map::nodes_matching_suffix`), but I don't know if we can remove `NodeId`s in there (I think when I attempted it previously there was some issue due to `HirId` not being representable with an integer) - in `ty::query::on_disk_cache` (not sure about the purpose of this one) - in `mir::transform::check_unsafety` (only important for error message order) Any suggestions how to kill these off? r? @Zoxc
2019-09-25Rollup merge of #64324 - alexcrichton:share-generics-again, r=michaelwoeristerMazdak Farrokhzad-4/+0
rustc: Fix mixing crates with different `share_generics` This commit addresses #64319 by removing the `dylib` crate type from the list of crate type that exports generic symbols. The bug in #64319 arises because a `dylib` crate type was trying to export a symbol in an uptream crate but it miscalculated the symbol name of the uptream symbol. This isn't really necessary, though, since `dylib` crates aren't that heavily used, so we can just conservatively say that the `dylib` crate type never exports generic symbols, forcibly removing them from the exported symbol lists if were to otherwise find them. The fix here happens in two places: * First is in the `local_crate_exports_generics` method, indicating that it's now `false` for the `Dylib` crate type. Only rlibs actually export generics at this point. * Next is when we load exported symbols from upstream crate. If, for our compilation session, the crate may be included from a dynamic library, then its generic symbols are removed. When the crate was linked into a dynamic library its symbols weren't exported, so we can't consider them a candidate to link against. Overally this should avoid situations where we incorrectly calculate the upstream symbol names in the face of differnet `share_generics` options, ultimately... Closes #64319

2019-09-23rustc: Convert `dependency_formats` to a queryAlex Crichton-4/+0
This commit converts a field of `Session`, `dependency_formats`, into a query of `TyCtxt`. This information then also needed to be threaded through to other remaining portions of the linker, but it's relatively straightforward. The only change here is that instead of `HashMap<CrateType, T>` the data structure changed to `Vec<(CrateType, T)>` to make it easier to deal with in queries.
2019-09-14feature_gate: Remove dead code from attribute checkingVadim Petrochenkov-9/+2
Same checks are performed during name resolution, and all attributes go through name resolution now
2019-09-11Move call site of `dep_graph_future()`.Nicholas Nethercote-4/+0
`Compiler::register_plugins()` calls `passes::register_plugins()`, which calls `Compiler::dep_graph_future()`. This is the only way in which a `passes` function calls a `Compiler` function. This commit moves the `dep_graph_future()` call out of `passes::register_plugins()` and into `Compiler::register_plugins()`, which is a more sensible spot for it. This will delay the loading of the dep graph slightly -- from the middle of plugin registration to the end of plugin registration -- but plugin registration is fast enough (especially compared to expansion) that the impact should be neglible.

2019-08-24Improve Rustdoc's handling of procedural macrosAaron Hill-21/+16
Fixes #58700 Fixes #58696 Fixes #49553 Fixes #52210 This commit removes the special rustdoc handling for proc macros, as we can now retrieve their span and attributes just like any other item. A new command-line option is added to rustdoc: `--crate-type`. This takes the same options as rustc's `--crate-type` option. However, all values other than `proc-macro` are treated the same. This allows Rustdoc to enable 'proc macro mode' when handling a proc macro crate. In compiletest, a new 'rustdoc-flags' option is added. This allows us to pass in the '--proc-macro-crate' flag in the absence of Cargo. I've opened [an additional PR to Cargo](https://github.com/rust-lang/cargo/pull/7159) to support passing in this flag. These two PRS can be merged in any order - the Cargo changes will not take effect until the 'cargo' submodule is updated in this repository.

rustc: Stabilize options for pipelined compilation This commit stabilizes options in the compiler necessary for Cargo to enable "pipelined compilation" by default. The concept of pipelined compilation, how it's implemented, and what it means for rustc are documented in #60988. This PR is coupled with a PR against Cargo (rust-lang/cargo#7143) which updates Cargo's support for pipelined compliation to rustc, and also enables support by default in Cargo. (note that the Cargo PR cannot land until this one against rustc lands). The technical changes performed here were to stabilize the functionality proposed in #60419 and #60987, the underlying pieces to enable pipelined compilation support in Cargo. The issues have had some discussion during stabilization, but the newly stabilized surface area here is: * A new `--json` flag was added to the compiler. * The `--json` flag can be passed multiple times. * The value of the `--json` flag is a comma-separated list of directives. * The `--json` flag cannot be combined with `--color` * The `--json` flag must be combined with `--error-format=json` * The acceptable list of directives to `--json` are: * `diagnostic-short` - the `rendered` field of diagnostics will have a "short" rendering matching `--error-format=short` * `diagnostic-rendered-ansi` - the `rendered` field of diagnostics will be colorized with ansi color codes embedded in the string field * `artifacts` - JSON blobs will be emitted for artifacts being emitted by the compiler The unstable `-Z emit-artifact-notifications` and `--json-rendered` flags have also been removed during this commit as well.
