Eventually we would like to reach a point where all backends support these approximately equally, but until then we have to work around some of these nuances of support being observable. Introduce the `cfg_target_has_reliable_f16_f128` internal feature, which provides the following new configuration gates: * `cfg(target_has_reliable_f16)` * `cfg(target_has_reliable_f16_math)` * `cfg(target_has_reliable_f128)` * `cfg(target_has_reliable_f128_math)` `reliable_f16` and `reliable_f128` indicate that basic arithmetic for the type works correctly. The `_math` versions indicate that anything relying on `libm` works correctly, since sometimes this hits a separate class of codegen bugs. These options match configuration set by the build script at [1]. The logic for LLVM support is duplicated as-is from the same script. There are a few possible updates that will come as a follow up. The config introduced here is not planned to ever become stable, it is only intended to replace the build scripts for `std` tests and `compiler-builtins` that don't have any way to configure based on the codegen backend.

Toward the end of -the cycle, we will review any comments and make a final determination -whether to convert the warning into a hard error or remove it -entirely. -``` +[template]: https://github.com/rust-lang/rust/issues/new?template=tracking_issue_future.md ### Issuing future compatibility warnings From c040e9f6fc51f9198cab65f021cd80a14fae5f52 Mon Sep 17 00:00:00 2001 From: Samuel Tardieu Date: Sun, 11 May 2025 17:33:20 +0200 Subject: [PATCH 129/200] `return_and_then`: only lint returning expressions If an expression is not going to return from the current function of closure, it should not get linted. This also allows `return` expression to be linted, in addition to the final expression. Those require blockification and proper indentation. --- clippy_lints/src/methods/return_and_then.rs | 28 +++++++---- tests/ui/return_and_then.fixed | 52 +++++++++++++++++++++
