Add arm64e-apple-ios & arm64e-apple-darwin targets #115526

arttet · 2023-09-04T08:18:25Z

This introduces

arm64e-apple-ios
arm64e-apple-darwin

Rust targets for support arm64e architecture on iOS and Darwin.

So, this is a first approach for integrating to the Rust compiler.

Tier 3 Target Policy

A tier 3 target must have a designated developer or developers (the "target
maintainers") on record to be CCed when issues arise regarding the target.
(The mechanism to track and CC such developers may evolve over time.)

I will be the target maintainer.

Targets must use naming consistent with any existing targets; for instance, a
target for the same CPU or OS as an existing Rust target should use the same
name for that CPU or OS. Targets should normally use the same names and
naming conventions as used elsewhere in the broader ecosystem beyond Rust
(such as in other toolchains), unless they have a very good reason to
diverge. Changing the name of a target can be highly disruptive, especially
once the target reaches a higher tier, so getting the name right is important
even for a tier 3 target.
Target names should not introduce undue confusion or ambiguity unless
absolutely necessary to maintain ecosystem compatibility. For example, if
the name of the target makes people extremely likely to form incorrect
beliefs about what it targets, the name should be changed or augmented to
disambiguate it.
If possible, use only letters, numbers, dashes and underscores for the name.
Periods (.) are known to cause issues in Cargo.

The target names arm64e-apple-ios, arm64e-apple-darwin were derived from aarch64-apple-ios, aarch64-apple-darwin.
In this ticket, people discussed the best suitable names for these targets.

In some cases, the arm64e arch might be "different". For example:

thread_set_state might fail with (os/kern) protection failure if we try to call it from arm64 process to arm64e process.

The returning value of dlsym is PAC signed on arm64e, while left untouched on arm64

Some function like pthread_create_from_mach_thread requires a PAC signed function pointer on arm64e, which is not required on arm64.

So, I have chosen them because there are similar triplets in LLVM. I think there are no more suitable names for these targets.

Tier 3 targets may have unusual requirements to build or use, but must not
create legal issues or impose onerous legal terms for the Rust project or for
Rust developers or users.
The target must not introduce license incompatibilities.
Anything added to the Rust repository must be under the standard Rust
license (MIT OR Apache-2.0).
The target must not cause the Rust tools or libraries built for any other
host (even when supporting cross-compilation to the target) to depend
on any new dependency less permissive than the Rust licensing policy. This
applies whether the dependency is a Rust crate that would require adding
new license exceptions (as specified by the tidy tool in the
rust-lang/rust repository), or whether the dependency is a native library
or binary. In other words, the introduction of the target must not cause a
user installing or running a version of Rust or the Rust tools to be
subject to any new license requirements.
Compiling, linking, and emitting functional binaries, libraries, or other
code for the target (whether hosted on the target itself or cross-compiling
from another target) must not depend on proprietary (non-FOSS) libraries.
Host tools built for the target itself may depend on the ordinary runtime
libraries supplied by the platform and commonly used by other applications
built for the target, but those libraries must not be required for code
generation for the target; cross-compilation to the target must not require
such libraries at all. For instance, rustc built for the target may
depend on a common proprietary C runtime library or console output library,
but must not depend on a proprietary code generation library or code
optimization library. Rust's license permits such combinations, but the
Rust project has no interest in maintaining such combinations within the
scope of Rust itself, even at tier 3.
"onerous" here is an intentionally subjective term. At a minimum, "onerous"
legal/licensing terms include but are not limited to: non-disclosure
requirements, non-compete requirements, contributor license agreements
(CLAs) or equivalent, "non-commercial"/"research-only"/etc terms,
requirements conditional on the employer or employment of any particular
Rust developers, revocable terms, any requirements that create liability
for the Rust project or its developers or users, or any requirements that
adversely affect the livelihood or prospects of the Rust project or its
developers or users.

No dependencies were added to Rust.

Neither this policy nor any decisions made regarding targets shall create any
binding agreement or estoppel by any party. If any member of an approving
Rust team serves as one of the maintainers of a target, or has any legal or
employment requirement (explicit or implicit) that might affect their
decisions regarding a target, they must recuse themselves from any approval
decisions regarding the target's tier status, though they may otherwise
participate in discussions.

This requirement does not prevent part or all of this policy from being
cited in an explicit contract or work agreement (e.g. to implement or
maintain support for a target). This requirement exists to ensure that a
developer or team responsible for reviewing and approving a target does not
face any legal threats or obligations that would prevent them from freely
exercising their judgment in such approval, even if such judgment involves
subjective matters or goes beyond the letter of these requirements.

Understood.
I am not a member of a Rust team.

Tier 3 targets should attempt to implement as much of the standard libraries
as possible and appropriate (core for most targets, alloc for targets
that can support dynamic memory allocation, std for targets with an
operating system or equivalent layer of system-provided functionality), but
may leave some code unimplemented (either unavailable or stubbed out as
appropriate), whether because the target makes it impossible to implement or
challenging to implement. The authors of pull requests are not obligated to
avoid calling any portions of the standard library on the basis of a tier 3
target not implementing those portions.

Understood.
std is supported.

The target must provide documentation for the Rust community explaining how
to build for the target, using cross-compilation if possible. If the target
supports running binaries, or running tests (even if they do not pass), the
documentation must explain how to run such binaries or tests for the target,
using emulation if possible or dedicated hardware if necessary.

Building is described in the derived target doc.

Tier 3 targets must not impose burden on the authors of pull requests, or
other developers in the community, to maintain the target. In particular,
do not post comments (automated or manual) on a PR that derail or suggest a
block on the PR based on a tier 3 target. Do not send automated messages or
notifications (via any medium, including via @) to a PR author or others
involved with a PR regarding a tier 3 target, unless they have opted into
such messages.

Backlinks such as those generated by the issue/PR tracker when linking to
an issue or PR are not considered a violation of this policy, within
reason. However, such messages (even on a separate repository) must not
generate notifications to anyone involved with a PR who has not requested
such notifications.

Understood.

Patches adding or updating tier 3 targets must not break any existing tier 2
or tier 1 target, and must not knowingly break another tier 3 target without
approval of either the compiler team or the maintainers of the other tier 3
target.

In particular, this may come up when working on closely related targets,
such as variations of the same architecture with different features. Avoid
introducing unconditional uses of features that another variation of the
target may not have; use conditional compilation or runtime detection, as
appropriate, to let each target run code supported by that target.

These targets are not fully ABI compatible with arm64e code.

These commits modify compiler targets.
(See the Target Tier Policy.)

These commits modify the Cargo.lock file. Unintentional changes to Cargo.lock can be introduced when switching branches and rebasing PRs.

If this was unintentional then you should revert the changes before this PR is merged.
Otherwise, you can ignore this comment.

Urgau

Could you address the requirements of the target tier policy in the PR description (Tier 3 in your case). As well as adding your target in the src/doc/rustc/src/platform-support.md page.

Example from another PR can be found here.

We intentionally split pauth into paca and pacg (#93782). why not use them?

Also, this adds stable target feature, but I'm not sure if adding a new target feature without a period of unstable is acceptable.

What is the best way to check that features exist?
On that PR, they were looking for the too small pattern, weren't they?

We can probably do the same thing that #114332 did for the c target feature. (i.e., add symbols to compiler/rustc_span/src/symbol.rs and then check to see if sess.unstable_target_features contains them.)

Do we actually need user facing intrinsics for this? I did expect the compiler to insert calles where necessary and if user code needs to explicitly use the pointer authentication instructions for whatever reason, it can use inline asm.

I think we might face issues, and we will have to call it directly. But presently, I have removed it. It seems asm will be complicated for this.

bjorn3 · 2023-09-04T13:51:50Z

I think we shouldn't add a tier 2 target for this until it actually is ABI compatible with arm64e code. Currently passing a rust function pointer to C code and calling it would crash due to the missing authentication tag in the pointer. Maybe make it a tier 3 target for now and have a big warning in the docs for this?

arttet · 2023-09-04T14:28:49Z

Agree. Now it is a tier 3.

While its not a Git conflict, all of the legacy bitcode stuff was removed from the other targets last night in #117364. I can open a follow-up PR to remove it here as well if you don't want to do it since the timing is kinda awkward.

If you could open a followup PR, that would be awesome :) I'd rather not have @arttet wait on another round of review (i.e. me)

Will do. I'll watch for this one to merge then followup.
