Description
Motivation and Context
CUDA 13.3 can emit unresolved XQA
kernel_mhareferences when SM75 and SM80+ architectures are compiled together, causing the final shared-library link to fail. XQA requires SM80+, so excluding its sources from the SM75 compilation pass avoids the inconsistent kernel emission.
