See tracking issue for these targets in #73628.

Building a project using the arm64e-apple-ios target fails to link when using Xcode 15.4. Using Xcode 14.3.1 works.

This might also be the case for arm64e-apple-darwin, but I can't test that due to rust-lang/cc-rs#1205.

$ cargo new foo && cd foo && cargo +nightly build --target=arm64e-apple-ios -Zbuild-std
// Or
$ ./x test --target=arm64e-apple-ios

The exact error is:

          Undefined symbols for architecture arm64e:
            "_main", referenced from:
                <initial-undefines>
          ld: symbol(s) not found for architecture arm64e
          clang: error: linker command failed with exit code 1 (use -v to see invocation)

I feel fairly confident that we're passing the right arguments to the linker nowadays (this happens even with #129369), so I suspect it's the object files that we generate that's the problem somehow, but I may be mistaken?

LLVM version: 19.1.0

Happens as far back as +nightly-2023-11-22, the day after the PR introducing these merged, so it's definitely due to changes in Xcode, not because of a regression in rustc.

The .old prefix in the warnings getting spammed would seem to hint that Apple has added a new identifier or ABI version for the arm64e target? This seems to indicate its an upstream LLVM limitation, perhaps.

Firefox has patched their LLVM build to set the correct arch flags based on Apple's LLVM output.

Hey @madsmtm,

You can handle it if you use the LLVM linker (lld).

--set rust.use-lld=true

./configure \
		--enable-option-checking \
		--enable-verbose-tests \
		--codegen-backends=llvm \
		--enable-codegen-tests \
		--enable-dist-src \
		--tools=cargo,clippy,rustdoc,rustfmt,rust-analyzer,analysis,src \
		--target=arm64e-apple-ios,aarch64-apple-ios,arm64e-apple-darwin,aarch64-apple-darwin \
		--set llvm.download-ci-llvm=true \
		--set build.verbose=0 \
		--set rust.channel=dev \
		--set rust.description="" \
		--set rust.use-lld=true \
		--dist-compression-formats=xz \
		--prefix=install

See llvm/llvm-project#79543
