This is on nightly-x86_64-unknown-linux-gnu. I'm no expert on these things, but it looks like some stuff in core::arch got removed - at least _mm_movemask_pi8 is not in the nightly docs anymore.

It works for nightly-2020-09-14, so if you update and run into this run: rustup override set nightly-2020-09-14. You may need to install that version too.

@comath That's a great workaround but it isn't a solution...

rust-lang/stdarch#890 looks like the breaking change. I'm unsure if the code here needs to be updated or if the issue is in stdarch.

I found this by trying to compile ripgrep with SIMD: BurntSushi/ripgrep#1684

packed_simd should be changed to use _mm_movemask_epi8 instead. _mm_movemask_pi8 uses MMX registers which are somewhat broken on LLVM.

Alternatively just always use the fallback impl here:

packed_simd/src/codegen/reductions/mask/x86.rs

Line 26 in 28b5e16

fallback_impl!($id);

Pin the nightly version of rust
0259423 
CI was failing on the latest nightly versions of rust due to
rust-lang/packed_simd#288

This commit pins the version of nightly rust to an older version to
avoid this issue.
