Requirements

Building the target itself requires a 64-bit little endian ARMv8-A compiler that is supported by cc-rs.

Building the target

The target can be built by enabling it for a rustc build:

[build]
target = ["aarch64-unknown-linux-gnu"]

If cross-compiling, make sure your C compiler is included in $PATH, then add it to the bootstrap.toml:

[target.aarch64-unknown-linux-gnu]
cc = "aarch64-linux-gnu-gcc"
cxx = "aarch64-linux-gnu-g++"
ar = "aarch64-linux-gnu-ar"
linker = "aarch64-linux-gnu-gcc"

Building Rust programs

This target is distributed through rustup, and otherwise requires no special configuration.

Cross-compilation

This target can be cross-compiled from any host.

Testing

This target can be tested as normal with x.py on a 64-bit little endian ARMv8-A host or via QEMU emulation.
