std::sync::mpsc uses thread locals and depending on the order TLS dtors are run `rx.recv()` can panic when used in a TLS dtor.
Searching for `chdir` in the Rust documentation produces no useful results.
Moved -z ignore to add_as_needed Trying to cross-compile for sparcv9-sun-solaris getting an error message for -zignore Introduced when -z -ignore was separated here 22d0ab0 No formatting done Reproduce ``` bash rustup target add sparcv9-sun-solaris cargo new --bin hello && cd hello && cargo run --target=sparcv9-sun-solaris ``` config.toml [target.sparcv9-sun-solaris] linker = "gcc"
Fixes: rust-lang#84018 With `-Z instrument-coverage`, coverage reporting of dead blocks (for example, blocks dropped because a conditional branch is dropped, based on const evaluation) is now supported. If `instrument-coverage` is enabled, `simplify::remove_dead_blocks()` finds all dropped coverage `Statement`s and adds their `code_region`s as `Unreachable` coverage `Statement`s to the `START_BLOCK`, so they are still included in the coverage map. Check out the resulting changes in the test coverage reports in this PR.
Fix rust-lang#84769, follow up to rust-lang#84499, rust-lang#83667.
Clippy: Decreases indentation and improves readability Signed-off-by: wcampbell <wcampbell1995@gmail.com>
MinGW driver for COFF LLD doesn't currently translate GNU-style `--threads=N` to native `/threads:N`, so we have to pass the option in its native form to avoid an error. Also pass the `threads` flag to lld-link as well
This updates the documentation since `ptr::addr_of!` and `ptr::addr_of_mut!` are now stable. One might remove the distinction between the sections `# On packed structs` and `# Examples`, as the old section on packed structs was primarily to prevent users of doing unde- fined behavior, which is not necessary anymore. There is also a new section in "how to obtain a pointer", which referen- ces the `ptr::addr_of!` macros. This commit contains squashed commits from code review.

When encountering a path that can't have generics, do not call `generics_of`. This would happen when writing something like `path::this_is_a_mod<const_val>`. Fix rust-lang#84831.
…, r=pnkfelix Improve diagnostic for when field is never read Related to (but does not close) rust-lang#81658 This completes the first step of ``````@pnkfelix's`````` [mentoring instructions](rust-lang#81658 (comment)) but does not actually improve the diagnostics (yet!). The two tests are heavily reduced versions of code from the original bug report. I've confirmed that the reduced `field-used-in-ffi` test [fails on nightly](https://play.rust-lang.org/?version=nightly&mode=debug&edition=2018&gist=f0862c89ddca028c55c20a5ed05e679a) but [passes on stable](https://play.rust-lang.org/?version=stable&mode=debug&edition=2018&gist=f0862c89ddca028c55c20a5ed05e679a). This confirms that the regression is reproduced correctly. The `drop-only-field` test is a case that ``````@pnkfelix`````` mentioned in his mentoring instructions. It is not a regression, but will come in handy when we make the diagnostic smarter by looking at whether the field type implements `Drop`. Per the [rustc-dev-guide](https://rustc-dev-guide.rust-lang.org/tests/adding.html), each test includes a comment summarizing what it is about.
Update `ptr` docs with regards to `ptr::addr_of!` This updates the documentation since `ptr::addr_of!` and `ptr::addr_of_mut!` are now stable. One might remove the distinction between the sections `# On packed structs` and `# Examples`, as the old section on packed structs was primarily to prevent users of doing undefined behavior, which is not necessary anymore. Technically there is now wrong/outdated documentation on stable, but I don't think this is worth a point release 😉 Fixes rust-lang#83509. ``````@rustbot`````` modify labels: T-doc

…nkov Fix#84467 linker_args with --target=sparcv9-sun-solaris Trying to cross-compile for sparcv9-sun-solaris getting a error message for -zignore Introduced when -z -ignore was seperated here 22d0ab0 No formatting done Reproduce ``` bash rustup target add sparcv9-sun-solaris cargo new --bin hello && cd hello && cargo run --target=sparcv9-sun-solaris ``` config.toml [target.sparcv9-sun-solaris] linker = "gcc"
…lnay Add doc alias for `chdir` to `std::env::set_current_dir` Searching for `chdir` in the Rust documentation produces no useful results. I wrote some code recently that called `libc::chdir` and manually handled errors, because I didn't realize that the safe `std::env::set_current_dir` existed. I searched for `chdir` and `change_dir` and `change_directory` (the latter two based on the precedent of unabbreviating set by `create_dir`), and I also read through `std::fs` expecting to potentially find it there. Given that none of those led to `std::env::set_current_dir`, I think that provides sufficient justification to add this specific alias.

…nts, r=tmandry Report coverage `0` of dead blocks Fixes: rust-lang#84018 With `-Z instrument-coverage`, coverage reporting of dead blocks (for example, blocks dropped because a conditional branch is dropped, based on const evaluation) is now supported. If `instrument-coverage` is enabled, `simplify::remove_dead_blocks()` finds all dropped coverage `Statement`s and adds their `code_region`s as `Unreachable` coverage `Statement`s to the `START_BLOCK`, so they are still included in the coverage map. Check out the resulting changes in the test coverage reports in this PR. I also addressed an outstanding issue/request to move coverage tests from run-make-fulldeps to run-make (in commit 2).

Also pass the `threads` flag to lld-link (windows-msvc lld) as well.
