lane -> element for core::simd::Simd (rust-lang/portable-simd#338) 2023-04-22 19:07:46 -07:00

Implement dynamic byte-swizzle prototype (rust-lang/portable-simd#334) 
This is meant to be an example that is used to test
a Rust intrinsic against, which will replace it.
The interface is fairly direct and doesn't address
more nuanced or interesting permutations one can do,
nevermind on types other than bytes.

The ultimate goal is for direct LLVM support for this.

92259a4a6c Clarify elementwise cmp reduces 
Saying "elementwise (non-)equal" may suggest it returns a vector.
The comments should be clear that it instead reduces to a scalar.

71d4c36850 lane -> element for core::simd::Simd 
A while ago we began saying T, N instead of T, LANES in reference to Simd.
At some point that leaked in to us checking in code with const N: usize.
After a while, we had a discussion and agreed that "lanes", while common,
is unnecessary jargon for Rust learners who aren't familiar with SIMD, and
is fully interchangeable with terms for arrays like element and index.

But we never acted on that. Let's update the main type's docs, at least.
The example tweaks also enable removing a slated-for-removal nightly fn.

Remove formats [T; N] does not impl (rust-lang/portable-simd#337) 
Remove these extra formatting traits, as they are
inconsistent with how arrays and slices format,
and it can cause unnecessary code bloat in binaries.
We can revisit this if people ever agree on doing these
formatters for the other slice-y types.

Prefer to dispatch to the `impl `fmt::Debug for [T]`,
to reduce the chances of monomorphizing twice.
Inlining it seems like a good idea for similar reasons?
