Yuki Okushi 46b8e46fe1 Rollup merge of #78396 - josephlr:ermsb, r=petrochenkov ... Add compiler support for LLVM's x86_64 ERMSB feature This change is needed for compiler-builtins to check for this feature when implementing memcpy/memset. See: https://github.com/rust-lang/compiler-builtins/pull/365 Without this change, the following code compiles, but does nothing: ```rust #[cfg(target_feature = "ermsb")] pub unsafe fn ermsb_memcpy() { ... } ``` The change just does compile-time detection. I think that runtime detection will have to come in a follow-up CL to std-detect. Like all the CPU feature flags, this just references #44839 Signed-off-by: Joe Richey <joerichey@google.com>		2020-10-27 08:45:24 +09:00
