@rustbot modify labels: rollup

instead of calling into git or checking the modification time of files, simply print the warning if there is a very large number of "modified" files. also make the wording much softer, so false positives are less alarming.

- Just a copy of unsupported fs right now to reduce the noise from future PRs to allow for easier review. - For the full working version of fs on uefi, see [0] [0]: https://github.com/Ayush1325/rust/tree/uefi-file-full Signed-off-by: Ayush Singh <ayush@beagleboard.org>

This greatly reduces the number of places that actually use the `rustc_layout_scalar_valid_range_*` attributes down to just 3: ``` library/core\src\ptr\non_null.rs 68:#[rustc_layout_scalar_valid_range_start(1)] library/core\src\num\niche_types.rs 19: #[rustc_layout_scalar_valid_range_start($low)] 20: #[rustc_layout_scalar_valid_range_end($high)] ``` Everything else -- PAL Nanoseconds, alloc's `Cap`, niched FDs, etc -- all just wrap those `niche_types` types.

Signed-off-by: onur-ozkan <work@onurozkan.dev>

This API removes the need for several `unsafe` blocks, and leads to clearer code.

…r-builtins, r=jieyouxu support target specific `optimized-compiler-builtins` Makes it possible to control `optimized-compiler-builtins` for per target.

Overall result: ❌✅ regressions and improvements - please read the text below

Our benchmarks found a performance regression caused by this PR.
This might be an actual regression, but it can also be just noise.

Next Steps:

If the regression was expected or you think it can be justified,
please write a comment with sufficient written justification, and add
@rustbot label: +perf-regression-triaged to it, to mark the regression as triaged.
If you think that you know of a way to resolve the regression, try to create
a new PR with a fix for the regression.
If you do not understand the regression or you think that it is just noise,
you can ask the @rust-lang/wg-compiler-performance working group for help (members of this group
were already notified of this PR).
