[PATCH] D125705: [OpenMP] Don't build the offloading driver without a source input

[Yaxun Liu via Phabricator via cfe-commits]

yaxunl added a comment.

HIP toolchain allows clang driver to compile bundled bitcode or assembly for mixed host/device compilation or device-only multi-GPU compilation.

e.g.

clang --offload-arch=gfx906 --offload-arch=gfx908 a.bc b.s

Can you add a test to make sure this does not break HIP toolchain? Thanks.
