León Orell Valerian Liehr 7e123e4940 Rollup merge of #136147 - RalfJung:required-target-features-check-not-add, r=workingjubilee ... ABI-required target features: warn when they are missing in base CPU Part of https://github.com/rust-lang/rust/pull/135408: instead of adding ABI-required features to the target we build for LLVM, check that they are already there. Crucially we check this after applying `-Ctarget-cpu` and `-Ctarget-feature`, by reading `sess.unstable_target_features`. This means we can tweak the ABI target feature check without changing the behavior for any existing user; they will get warnings but the target features behave as before. The test changes here show that we are un-doing the "add all required target features" part. Without the full #135408, there is no way to take a way an ABI-required target feature with `-Ctarget-cpu`, so we cannot yet test that part. Cc ``@workingjubilee``		2025-01-29 03:12:21 +01:00
