[bug] error: unable to execute command: Aborted

I tried to build mullvad-browser using makepkg.
Then I got an "error: unable to execute command: Aborted (core dumped)" and the build stopped. Is this a bug in LLVM?

Seems like you are trying to build for the target that doesn't support AES-NI extension.

I tried to build mullvad-browser using makepkg. Then I got an "error: unable to execute command: Aborted (core dumped)" and the build stopped. Is this a bug in LLVM?

My CPU is an Intel Core i5-4440. There is aes in /proc/cpuinfo flags, is this not good enough?

Maybe rustc didn't pass target-features=+aes to LLVM. See also #53097 and #54055.
It has been fixed by rust-lang/rust#94579. Could you please try to build mullvad-browser with the latest rustc? You were using an old version of the rust toolchain (rustc 1.60.0 (7737e0b5c 2022-04-04)).

I removed target-cpu=native from RUSTFLAGS and replaced march=native with march=x86-64 in CFLAGS and CXXFLAGS and the build was successful.
However, if I change only RUSTFLAGS, the build still fails.
Is this a bug not only in rustc but also in llvm's C++ compiler?

Clang doesn't allow target-cpu=native:
