Add intrinsic-test alias and set sample rate This PR adds intrinsic-test alias and set sample rate. It sets sample percentage to 100% . r? @Kobzol
target_features: sse (or at least avx2) is incompatible with soft-float ABI Fixes rust-lang/rust#117938 Enabling both the avx2 and soft-float target features is [not supported by LLVM](rust-lang/rust#117938 (comment)) and can crash the backend. Let's preempt that with rust-level checks. (I still think there's also an LLVM bug here, it shouldn't just SIGILL on unexpected target feature configurations, but that's a different discussion.) What is not clear to me is whether this just affects just avx2 or also avx or even sse (we don't support mmx/3dnow separately). @dianqk do you know more about this? To be safe, let's reject "sse" and therefore by implication also all other x86 vector target features. This PR turns `#[target_feature(enable = "sse")]` on a softfloat target into an FCW similar to what we do on aarch64 (see rust-lang/rust#135160). The FCW only affects people building for soft-float targets which is a fairly small percentage of our overall users (and which means we cannot meaningfully crater this). I hence went for "report in deps" immediately so that the people building the actual binaries see these warnings that their upstreams probably will never see.

Looks like some lints etc changed with the new toolchain. What's the best way to handle this with josh? Fix on main first, or push fixes to this branch? |
|
It's fine to push here. The only rule is that the Josh commits can't ever be rebased or squashed. In fact it would be good to disable rebase/squash merges in this repo altogether, if that would be fine for you. |
Ok I have no idea what to do about this one :) |
