+# powerpc64-unknown-linux-musl
+
+**Tier: 3**
+
+Target for 64-bit big endian PowerPC Linux programs using musl libc.
+This target uses the ELF v2 ABI.

+
+## Requirements
+
+Building the target itself requires a 64-bit big endian PowerPC compiler that
+is supported by `cc-rs`.
+
+## Building the target
+
+The target can be built by enabling it for a `rustc` build.
+
+```toml
+[build]
+target = ["powerpc64-unknown-linux-musl"]
+```
+
+Make sure your C compiler is included in `$PATH`, then add it to the
+`bootstrap.toml`:
+
+```toml
+[target.powerpc64-unknown-linux-musl]
+cc = "powerpc64-linux-musl-gcc"
+cxx = "powerpc64-linux-musl-g++"
+ar = "powerpc64-linux-musl-ar"
+linker = "powerpc64-linux-musl-gcc"
+```
+
+## Building Rust programs
+
+Rust does not yet ship pre-compiled artifacts for this target. To compile for
+this target, you will first need to build Rust with the target enabled (see
+"Building the target" above).
+
+## 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 big endian PowerPC
+host or via QEMU emulation.
