I also don't know what is the best for emlinker, PtxLinker, MsvcLinker. The option for WasmLd is copied from https://aransentin.github.io/cwasm/.

r=kinnison,ollie27 Sort "implementations on foreign types" section in the sidebar Fixes #71926. We were sorting by the ID instead of sorting by the name. They're not in the same order as the implementations but I think it makes more sense this way considering this is what we do for the methods as well. r? @kinnison cc @rust-lang/rustdoc
2020-05-10Rollup merge of #71840 - matthewjasper:drop-trees, r=oli-obkRalf Jung-1749/+1618
Rework MIR drop tree lowering This PR changes how drops are generated in MIR construction. This is the first half of the fix for #47949. Rather than generating the drops for a given unwind/break/continue/return/generator drop path as soon as they are needed, the required drops are recorded and get generated later. The motivation for this is * It simplifies the caching scheme, because it's now possible to walk up the currently scheduled drop tree to recover state. * The basic block order for MIR more closely resembles execution order. This PR also: * Highlights cleanup blocks in the graphviz MIR output. * Removes some unnecessary drop flag assignments.

2020-05-10Auto merge of #72020 - alexcrichton:fix-incremental-linker-plugin-lto, r=oli-obkbors-35/+71
Fix disagreeement about CGU reuse and LTO This commit fixes an issue where the codegen backend's selection of LTO disagreed with what the codegen later thought was being done. Discovered in #72006 we have a longstanding issue where if `-Clinker-plugin-lto` in optimized mode is compiled incrementally it will always panic on the second compilation. The underlying issue turned out to be that the production of the original artifact determined that LTO should not be done (because it's being postponed to the linker) but the CGU reuse selection thought that LTO was done so it was trying to load pre-LTO artifacts which were never generated. The fix here is to ensure that the logic when generating code which determines what kind of LTO is being done is shared amongst the CGU reuse decision and the backend actually doing LTO. This means that they'll both be in agreement about whether the previous compilation did indeed produce incremental pre-LTO artifacts. Closes #72006

Simplify the `tcx.alloc_map` API This PR changes all functions that require manually locking the `alloc_map` to functions on `TyCtxt` that lock the map internally. In the same step we make the `TyCtxt::alloc_map` field private. r? @RalfJung
2020-05-09Rollup merge of #71234 - maurer:init-array, r=cuviperRalf Jung-1/+23
rustllvm: Use .init_array rather than .ctors LLVM TargetMachines default to using the (now-legacy) .ctors representation of init functions. Mixing .ctors and .init_array representations can cause issues when linking with lld. This happens in practice for: * Our profiling runtime which is currently implicitly built with .init_array since it is built by clang, which sets this field. * External C/C++ code that may be linked into the same process. Fixes: #71233

x.py: allow configuring the build directory This allows configuring the directory for build artifacts, instead of having it always be `./build`. This means you can set it to a constant location, letting you reuse the same cache while working in several different directories. The configuration lives in `config.toml` under `build.build-dir`. By default, it keeps the existing default of `./build`, but it can be configured to any relative or absolute path. Additionally, it allows making outputs relative to the root of the git repository using `$ROOT`. r? @Mark-Simulacrum
