@stephanosio or @nashif can either of you trigger the workflow here? I do not have permissions to do so. |

Tsk - yeah, sorry: the arm toolchain contains the compiler/linker/binutils but no QEMU. Is that a blocker or does it suffice to provide build-only capability for arm? |
Install codelinaro Hexagon LLVM 22.1.8 cross-toolchain for x86_64 and aarch64. Install qemu runtime dependencies. Smoke-test both clang and qemu-system-hexagon during the build. Signed-off-by: Brian Cain <brian.cain@oss.qualcomm.com>

I can try building qemu from source in the arm container build, if that's required. I didn't jump at that option because it requires a lot of build dependencies but it's probably doable w/o much trouble. |

Install the codelinaro Hexagon LLVM 22.1.8 cross-toolchain from artifacts.codelinaro.org for both x86_64 and aarch64 hosts.
On x86_64 the tarball extracts to x86_64-linux-gnu/; on aarch64 it extracts to aarch64-linux-musl/ and requires the musl package since the aarch64 clang binary links against musl libc. A host/ symlink is created in both cases so that ENV PATH can use a single static path (/opt/toolchains/hexagon/host/bin) regardless of host arch.
The toolchain is used with ZEPHYR_TOOLCHAIN_VARIANT=host and TOOLCHAIN_VARIANT_COMPILER=llvm to build Zephyr for the qemu_hexagon/qemu_hexagon_virt board target.
