This is only applicable when neither of --emit=llvm-ir or --emit=llvm-bc are not requested. In case either of these outputs are wanted, but the benefits of such context are desired as well, -Zfewer_names option provides the same functionality regardless of the outputs requested.

2017-09-30rustc: Enable LTO and multiple codegen unitsAlex Crichton-11/+2
This commit is a refactoring of the LTO backend in Rust to support compilations with multiple codegen units. The immediate result of this PR is to remove the artificial error emitted by rustc about `-C lto -C codegen-units-8`, but longer term this is intended to lay the groundwork for LTO with incremental compilation and ultimately be the underpinning of ThinLTO support. The problem here that needed solving is that when rustc is producing multiple codegen units in one compilation LTO needs to merge them all together. Previously only upstream dependencies were merged and it was inherently relied on that there was only one local codegen unit. Supporting this involved refactoring the optimization backend architecture for rustc, namely splitting the `optimize_and_codegen` function into `optimize` and `codegen`. After an LLVM module has been optimized it may be blocked and queued up for LTO, and only after LTO are modules code generated. Non-LTO compilations should look the same as they do today backend-wise, we'll spin up a thread for each codegen unit and optimize/codegen in that thread. LTO compilations will, however, send the LLVM module back to the coordinator thread once optimizations have finished. When all LLVM modules have finished optimizing the coordinator will invoke the LTO backend, producing a further list of LLVM modules. Currently this is always a list of one LLVM module. The coordinator then spawns further work to run LTO and code generation passes over each module. In the course of this refactoring a number of other pieces were refactored: * Management of the bytecode encoding in rlibs was centralized into one module instead of being scattered across LTO and linking. * Some internal refactorings on the link stage of the compiler was done to work directly from `CompiledModule` structures instead of lists of paths. * The trans time-graph output was tweaked a little to include a name on each bar and inflate the size of the bars a little

2017-09-18incr.comp.: Move result fingerprinting to DepGraph::with_task().Michael Woerister-0/+14
This makes sure that we don't introduce strange cases where we have nodes outside the query system that could break red/green tracking and it will allow to keep red/green neatly encapsulated within the DepGraph implementation.
2017-09-17rustc: Move codegen to a queryAlex Crichton-48/+10
This commit moves the actual code generation in the compiler behind a query keyed by a codegen unit's name. This ended up entailing quite a few internal refactorings to enable this, along with a few cut corners: * The `OutputFilenames` structure is now tracked in the `TyCtxt` as it affects a whole bunch of trans and such. This is now behind a query and threaded into the construction of the `TyCtxt`. * The `TyCtxt` now has a channel "out the back" intended to send data to worker threads in rustc_trans. This is used as a sort of side effect of the codegen query but morally what's happening here is the return value of the query (currently unit but morally a path) is only valid once the background threads have all finished. * Dispatching work items to the codegen threads was refactored to only rely on data in `TyCtxt`, which mostly just involved refactoring where data was stored, moving it from the translation thread to the controller thread's `CodegenContext` or the like. * A new thread locals was introduced in trans to work around the query system. This is used in the implementation of `assert_module_sources` which looks like an artifact of the old query system and will presumably go away once red/green is up and running.
2017-09-17rustc: Remove another global map from transAlex Crichton-12/+2
This commit removes the `crate_trans_items` field from the `CrateContext` of trans. This field, a big map, was calculated during partioning and was a set of all translation items. This isn't quite incremental-friendly because the map may change a lot but not have much effect on downstream consumers. Instead a new query was added for the one location this map was needed, along with a new comment explaining what the location is doing!
2017-09-17rustc: Mostly remove `ExportedSymbols`Alex Crichton-11/+1
This is a big map that ends up inside of a `CrateContext` during translation for all codegen units. This means that any change to the map may end up causing an incremental recompilation of a codegen unit! In order to reduce the amount of dependencies here between codegen units and the actual input crate this commit refactors dealing with exported symbols and such into various queries. The new queries are largely based on existing queries with filled out implementations for the local crate in addition to external crates, but the main idea is that while translating codegen untis no unit needs the entire set of exported symbols, instead they only need queries about particulare `DefId` instances every now and then. The linking stage, however, still generates a full list of all exported symbols from all crates, but that's going to always happen unconditionally anyway, so no news there!
2017-09-17rustc: Make trans collect/partition a queryAlex Crichton-4/+4
This commit moves the `collect_and_partition_translation_items` function into a query on `TyCtxt` instead of a free function in trans, allowing us to track dependencies and such of the function.
2017-09-17rustc: Calculate `ExportedSymbols` in a queryAlex Crichton-1/+1
This commit moves the definition of the `ExportedSymbols` structure to the `rustc` crate and then creates a query that'll be used to construct the `ExportedSymbols` set. This in turn uses the reachablity query exposed in the previous commit.
2017-09-17rustc_trans: Refactor collection to use tcxAlex Crichton-4/+4
This commit refactors the `collect_crate_translation_items` function to only require the `TyCtxt` instead of a `SharedCrateContext` in preparation for query-ifying this portion of trans.
