Detailed Description

This is used to control valid status that current MI supports.

For example, non floating point intrinsic such as @llvm.amdgcn.sdot2 does not support NEG bit on VOP3P. The class can be further extended to recognize support on SEL, NEG, ABS bit for different MI on different arch
