external-repos.md: small fixes
Partially reverts commit 40311c4.
See RUST-141600: this test is broken in two ways: 1. This test triggers `-Wincompatible-pointer-types` on GCC 14. 2. This test requires ARMv8.5+ w/ MTE extensions enabled, but GHA CI runner hardware do not have this enabled.
./x is recommended over running ./x.py directly, and is the more commonly-used invocation of bootstrap in the guide
use a consistent (and recommended) invocation
- --depth=1 is more useful for once-off uses, like on ci - .git postfix on github repo url is not needed
That is, calling it an example is misleading
Nowhere else is this called "Dist check"
add missing word
do not invent a name
distcheck has only one possible invocation
…buginfo, r=wesleywiser tests: Test line number in debuginfo for diverging function calls Closes rust-lang#59558 which just [E-needs-test](rust-lang#59558 (comment)). The bug seems to have been fixed in **nightly-2021-05-10**: ```sh for toolchain in nightly-2021-05-09 \ nightly-2021-05-10 \ 1.88; do echo -e "\nWith $toolchain:" rustc +$toolchain tests/codegen/diverging-function-call-debuginfo.rs --emit llvm-ir -o /tmp/out.ll -g -Clto -Copt-level=0 build/x86_64-unknown-linux-gnu/ci-llvm/bin/FileCheck --input-file /tmp/out.ll tests/codegen/diverging-function-call-debuginfo.rs --check-prefix=CHECK --dump-input-context 10 2>/dev/null && echo OK || echo FAIL done ``` ``` With nightly-2021-05-09: FAIL With nightly-2021-05-10: OK With 1.88: OK ``` which gives the following list of candidate commits. Not clear which one it is exactly but it doesn't matter much since we can confirm that the test works.

rustc-dev-guide subtree update r? ghost
Copy GCC sources into the build directory even outside CI It takes ~3.5s on my Linux notebook to perform the copy, but it should only be executed when we actually go build GCC, and that will almost certainly take much longer :) So I think it should be fine. At least we won't be polluting the source directory for local builds. Fixes: rust-lang#143986 r? `@nikic`
