This commit stabilizes the SIMD in Rust for the x86/x86_64 platforms. Notably
this commit is stabilizing:

  • The std::arch::{x86, x86_64} modules and the intrinsics contained inside.
  • The is_x86_feature_detected! macro in the standard library
  • The #[target_feature(enable = "...")] attribute
  • The #[cfg(target_feature = "...")] matcher

Stabilization of the module and intrinsics were primarily done in
rust-lang-nursery/stdsimd#414 and the two attribute stabilizations are done in
this commit. The standard library is also tweaked a bit with the new way that
stdsimd is integrated.

Note that other architectures like std::arch::arm are not stabilized as part
of this commit, they will likely stabilize in the future after they've been
implemented and fleshed out. Similarly the std::simd module is also not being
stabilized in this commit, only std::arch. Finally, nothing related to __m64
is stabilized in this commit either (MMX), only SSE and up types and intrinsics
are stabilized.

Closes #29717
Closes #44839
Closes #48556

Note it's not intended that this should merge before the FCP lapses in #48556, but rather this is submitted early to get some more time for review

Doesn't this stabilise all the (whitelisted) feature names for all the architectures, or am I mistaken? The RFC mentioned this specific set https://github.com/rust-lang/rfcs/blob/master/text/2325-stable-simd.md#the-target_feature-attribute.

The std::arch::{x86, x86_64} modules and the intrinsics contained inside.

What is the difference between the std::arch::x86 and std::arch::x86_64? Typically x86 includes x86_64 so it seems odd that it is separate. Does x86 refer to 32-bit x86 only?

is_x86_feature_detected!

Why do we have a macro specific to x86? Does that also apply to the std::arch::x86_64 or just std::arch::x86? Do we no longer have a global namespace of CPU features?

From IRC last night:

20:51 < Gankro> acrichto: why is the is_x86_feature_detected! so precisely named? Why can't it be is_feature_detected?
20:55 <~acrichto> Gankro: it doesn't work on other paltforms
20:55 <~acrichto> in that the arguments are x86-specific
20:55 <~acrichto> (so there's a macro for each arch)
20:56 < Gankro> acrichto: why couldn't it just return false on the plats?
20:57 < Gankro> *other plats
20:57 <~acrichto> Gankro: catches typos and such
20:57 <~acrichto> in that it's currently a deliberate decision
20:57 <~acrichto> (we've discussed this a bunch historically)
20:57 < Gankro> ok
20:57 <~acrichto> it turns out that if the macros is cross paltform it doesn't really help at all
20:57 <~acrichto> it's only invoked in platform-specific contexts anyway

There is a module per target_arch which is used conditionally, and the module name, like std::os, indicates the non-portability. The std::arch::x86 std::arch::x86_64 module is not defined on i686-unknown-linux-gnu, for example.

Why do we have a macro specific to x86? Does that also apply to the std::arch::x86_64 or just std::arch::x86? Do we no longer have a global namespace of CPU features?

As explained by @steveklabnik the macro is x86-specific in its feature detection and list of accepted features. For convenience there is no is_x86_64_feature_detected! macro as it's much more difficult to conditionally invoke macros than work with use. Each platform has its own macro with its own accepted set of arguments, again indicated by the name of the macro.

So are there modules for i286, i386, i486, i586, i786 too? It doesn't seem terribly useful to have this many variants of x86. What is the justification for this?

That doesn't answer the question. Why do we have platform specific macros instead of a single macro? and why does the justification for that not apply to #target_feature(..) or #[cfg(target_feature = ..))?

@parched ah yes, thanks! I've pushed a commit which should allow us to tweak the stability of each target feature.

No, there are not all those modules. I'd recommend reading the RFC and the issue tracker for stdsimd for rationale here. There are only modules for each target_arch, similar to how std::os has only the modules that match #[cfg] like unix/windows/linux/...

That doesn't answer the question. Why do we have platform specific macros instead of a single macro? and why does the justification for that not apply to #target_feature(..) or #[cfg(target_feature = ..))?

The answer to your question was indicated in the IRC logs, a platform-independent macro in no way makes SIMD easier to use. Previous attempts at using the same name and same namespace for attributes didn't provide any ergonomics so a platform-specific macro is the conservative option.

@alexcrichton Did you have a typo in this sentence?

The std::arch::x86 module is not defined on i686-unknown-linux-gnu, for example.

I would have expected either of:

  1. The std::arch::x86 module is not defined on x86_64-unknonw-linux-gnu
  2. The std::arch::x86_64 module is not defined on i686-unknown-linux-gnu

Er oops sorry yeah, @rkruppe you are correct! (both of those alternatives are true)

I'd expect to have std::arch::x86_16, std::arch::x86_32 and std::arch::x86_64 for x86 or just a single std::arch::x86 which covers all modes. Similarly for ARM std::arch::aarch32, std::arch::aarch64 and possibly std::arch::t32 or something for Thumb.

The answer to your question was indicated in the IRC logs, a platform-independent macro in no way makes SIMD easier to use.

How does having a platform-independent macro make SIMD harder to use?

Previous attempts at using the same name and same namespace for attributes didn't provide any ergonomics so a platform-specific macro is the conservative option.

By that logic we should also have platform-specific versions of #[target_feature(..)] and #[cfg(target_feature = ..)). Using a platform-specific macro doesn't necessary in other to be conservative, just having a namespace per architecture should suffice.

This does not match #[cfg(target_arch)], the modules match the well-established convention in Rust with #[cfg(target_arch)]

How does having a platform-independent macro make SIMD harder to use?

You've misread that, I said that it wasn't easier to use, not harder to use.

Stabilize x86/x86_64 SIMD
This commit stabilizes the SIMD in Rust for the x86/x86_64 platforms. Notably
this commit is stabilizing:

* The `std::arch::{x86, x86_64}` modules and the intrinsics contained inside.
* The `is_x86_feature_detected!` macro in the standard library
* The `#[target_feature(enable = "...")]` attribute
* The `#[cfg(target_feature = "...")]` matcher

Stabilization of the module and intrinsics were primarily done in
rust-lang-nursery/stdsimd#414 and the two attribute stabilizations are done in
this commit. The standard library is also tweaked a bit with the new way that
stdsimd is integrated.

Note that other architectures like `std::arch::arm` are not stabilized as part
of this commit, they will likely stabilize in the future after they've been
implemented and fleshed out. Similarly the `std::simd` module is also not being
stabilized in this commit, only `std::arch`. Finally, nothing related to `__m64`
is stabilized in this commit either (MMX), only SSE and up types and intrinsics
are stabilized.

Closes #29717
Closes #44839
Closes #48556

💔 Test failed - status-appveyor

Separately gate each target_feature feature
Use an explicit whitelist for what features are actually stable and can be
enabled.
