Some vqs don't need to be allocated when the related feature bits are disabled. Callers notice the vq allocation layer by setting the related names[i] to be NULL. This patch series fixes the find_vqs implementations to handle this case. Wei Wang (2): virtio_pci: use queue idx instead of array idx to set up the vq virtio: don't allocate vqs when names[i] = NULL

Hi, I’ve run into a case where `llc -mattr=+soft-float` for "armv7-unknown-linux-androideabi” segfaults, while `llc -float-abi=soft` does not. Similarly if the "target-features"="+soft-float” metadata is embedded, llc segfaults. I fear I’m missing something rather subtle here, could someone help me understand the differences? Cheers, Moritz
