2020-07-31Auto merge of #74958 - Mark-Simulacrum:stable-next, r=pnkfelixbors-53/+49
[stable] 1.45.2 release This is intended to fix the stable breakage noted in #74954, but does *not* close that issue -- there remains investigation and likely nightly/beta fixes need to be issued as well. r? @pnkfelix

Stable backport of #73613 This is the backport of #73613 to stable. r? @ghost cc @Mark-Simulacrum In addition the tests added in the original PR passing, I've also confirmed that the test case in #74739 works correctly.

2020-07-23ci: Replace exec-with-shell wrapper with "plain bash"Kristofer Rye-41/+5
Also, promote defaults.run.shell from inside only the primary jobs to the top level. The src/ci/exec-with-shell.py wrapper script was formerly used to change out the shell mid-job by intercepting a CI_OVERRIDE_SHELL environment variable. Now, instead, we just set `bash` as the global default across all jobs, and we also delete the exec-with-shell.py script. Signed-off-by: Kristofer Rye <kristofer.rye@gmail.com>
2020-07-23ci: Stop setting CI_OVERRIDE_SHELL environment variableKristofer Rye-2/+15
This will render the src/ci/exec-with-shell.py script more or less useless, but we're going to replace that by just using the system bash instead. Signed-off-by: Kristofer Rye <kristofer.rye@gmail.com>
2020-07-23ci: Set `shell: bash` as a default, remove duplicatesKristofer Rye-80/+12
A follow-up to #74406, this commit merely removes the `shell: bash` lines where they are explicitly added in favor of setting defaults for *all* "run" steps. Signed-off-by: Kristofer Rye <kristofer.rye@gmail.com>

This is not a user-visible change as Cargo's library API is not exposed by Rust, but this way the version in 1.45.1 will appropriately match with published Cargo 0.46.1.

2020-07-10ci: fix wasm32 broken due to a NodeJS version bumpPietro Albini-1/+12
Emscripten's SDK recently bumped the version of NodeJS they shipped, but our Dockerfile for the wasm32 builder hardcoded the version number. This will cause consistent CI failures once the currently cached image is rebuilt (either due to a change or due to the cache expiring). This commit fixes the problem by finding the latest version of NodeJS in the Emscripten SDK and symlinking it to a "latest" directory, which is then added to the PATH.
2020-07-10Change how compiler-builtins gets many CGUsAlex Crichton-48/+15
This commit intends to fix an accidental regression from #70846. The goal of #70846 was to build compiler-builtins with a maximal number of CGUs to ensure that each module in the source corresponds to an object file. This high degree of control for compiler-builtins is desirable to ensure that there's at most one exported symbol per CGU, ideally enabling compiler-builtins to not conflict with the system libgcc as often. In #70846, however, only part of the compiler understands that compiler-builtins is built with many CGUs. The rest of the compiler thinks it's building with `sess.codegen_units()`. Notably the calculation of `sess.lto()` consults `sess.codegen_units()`, which when there's only one CGU it disables ThinLTO. This means that compiler-builtins is built without ThinLTO, which is quite harmful to performance! This is the root of the cause from #73135 where intrinsics were found to not be inlining trivial functions. The fix applied in this commit is to remove the special-casing of compiler-builtins in the compiler. Instead the build system is now responsible for special-casing compiler-builtins. It doesn't know exactly how many CGUs will be needed but it passes a large number that is assumed to be much greater than the number of source-level modules needed. After reading the various locations in the compiler source, this seemed like the best solution rather than adding more and more special casing in the compiler for compiler-builtins. Closes #73135

2020-07-10rustdoc: Fix doc aliases with crate filteringOliver Middleton-8/+55
Fix a crash when searching for an alias contained in the currently selected filter crate. Also remove alias search results for crates that should be filtered out. The test suite needed to be fixed to actually take into account the crate filtering and check that there are no results when none are expected.
