v19.1.2

This is a cross-toolchain built from public source repositories. It can make and analyze binaries for hexagon-unknown-linux-musl and hexagon-unknown-none-elf. hexagon-unknown-none-elf is a baremetal target that does not have any platform support like bootstrapping/loaders nor a C library.

These toolchains were built from the LLVM 19.1.2 release.
