Typo: enable Also, drop the part about the extent (NumRecords) -- that's not a requirement of the compiler, it's a requirement of the HW and should be implied by stating that the buffer descriptor is "raw". (And it is also incorrect on IIRC gfx8, which had NUM_RECORDS always in units of bytes) https://github.com/llvm/llvm-project/pull/74471 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
