trap at Instance `x86::sse::_mm_prefetch` #1448

Closed luxalpa closed 5 months ago

luxalpa commented 5 months ago

I'm getting this error (on Windows):

trap at Instance { def: Item(DefId(2:13956 ~ core[ba5e]::core_arch::x86::sse::_mm_prefetch)), args: [3_i32] } (_ZN4
core9core_arch3x863sse12_mm_prefetch17h8b14a40b0b8e680cE): llvm.prefetch

Not entirely sure what it means. Missing intrinsic maybe?

Could you try the llvm-prefetch branch? Github actions is having an outage right now, so I unfortunately can't provide a prebuilt version until the outage is solved.

Thanks, I tried the branch, it works perfectly! 🐉
