…crichton Upgrade GCC to 8.3.0, glibc to 1.17.0 and crosstool-ng to 1.24.0 for dist-armv7-linux rust-lang#62896 was caused by the usage of the GCC 5.2.0 toolchain, which was released back in 2015 and may have bugs affecting LLVM 9. This PR upgrade GCC to 8.3.0 from 5.2.0, glibc from 1.16.0 to 1.17.0 and crosstool-ng to 1.24.0 only for dist-armv7-linux. Fixes rust-lang#62896 r? @alexcrichton

This looks like the only place calculating dominators from the MIR body every time instead of using the ones stored on the `MirBorrowckCtxt`. For example, in rust-lang#65131 a big generated function with a number of borrowck errors takes a few hours(!) recalculating the dominators while explaining the errors. I don't know enough about this part of rustc codebase to know for sure that this change is correct, but no tests seem to fail as a result of this change in local testing.

@gnzlbg

…king-rust-abi-unwind-issue-64655, r=alexcrichton Always mark rust and rust-call abi's as unwind PR rust-lang#63909 identified a bug that had been injected by PR rust-lang#55982. As discussed on rust-lang#64655 (comment) , we started marking extern items as nounwind, *even* extern items that said they were using "Rust" or "rust-call" ABI. This is a more targeted variant of PR rust-lang#63909 that fixes the above bug. Fix rust-lang#64655 ---- I personally suspect we will want PR rust-lang#63909 to land in the long-term But: * it is not certain that PR rust-lang#63909 *will* land, * more importantly, PR rust-lang#63909 almost certainly will not be backported to beta/stable. The identified bug was more severe than I think anyone realized (apart from perhaps @gnzlbg, as noted [here](rust-lang#63909 (comment))). Thus, I was motivated to write this PR, which fixes *just* the issue with extern rust/rust-call functions, and deliberately avoids injecting further deviation from current behavior (you can see further notes on this in the comments of the code added here).

This commit silences the unreachable code lint when it originates from within a await desugaring. Signed-off-by: David Wood <[email protected]>

…, r=petrochenkov" This reverts commit ef1ecbe, reversing changes made to fc8765d. That changed unfortunately broke rustfix on windows: rust-lang/rustfix#176 Specifically, what ef1ecbe did was to enforce normalization of \r\n to \n at file loading time, similarly to how we deal with Byte Order Mark. Normalization changes raw offsets in files, which are exposed via `--error-format=json`, and used by rusfix. The proper solution here (which also handles the latent case with BOM) is rust-lang#65074 However, since it's somewhat involved, and we are time sensitive, we prefer to revert the original change on beta.
