Compilation fails: Intrinsic argument has wrong type

When trying to build a crate depending on simd:

I've been tweaking and improving the compiler progressively, and simd has been tracking the changes, but if you're pinned to an older version of simd, or are using an older compiler, the mismatch may cause errors like this. The former should be fixed with a cargo update and the latter will just need a rustc update.

Thanks for filing nonetheless, and if upgrading things doesn't resolve it (or you have problems) be sure to just ask.

Ah, yeah, this is entirely my fault. I thought my version of the compiler was up to date, but apparently I hadn't updated it for several days. Whoops, sorry for bugging you.
