This adds Hurd toolchain support to Clang's driver in addition to handling
translating the triple from GCC toolchain-compatible form (x86_64-gnu) to
the actual triple registered in LLVM (x86_64-pc-hurd-gnu).

@llvmbot llvmbot added clang Clang issues not falling into any other category clang:driver 'clang' and 'clang++' user-facing binaries. Not 'clang-cl' clang:frontend Language frontend issues, e.g. anything involving "Sema" labels Jan 13, 2024

Thanks for the patch. It's in a very good shape and I did not need to make many nitpicky comments like I had to do for other "support a new target triple" driver patches:)

Hurd: Add x86_64 support
309b4f3 
This adds Hurd toolchain support to Clang's driver in addition to handling
translating the triple from GCC toolchain-compatible form (x86_64-gnu) to
the actual triple registered in LLVM (x86_64-pc-hurd-gnu).

Hurd: Add x86_64 support (llvm#78065)
1ee02d4 
This adds Hurd toolchain support to Clang's driver in addition to
handling
translating the triple from GCC toolchain-compatible form (x86_64-gnu)
to
the actual triple registered in LLVM (x86_64-pc-hurd-gnu).
