I didn't think an explicit "return false" would be helpful - if Cache is empty at this point then the loop immediately below will do zero iterations and we'll hit the "return false" immediately below that.

The only other similar assert I found was the one in the next inner class down, MFMASmallGemmSingleWaveOpt::IsPermForDSW . Again this will return false if Cache is empty due to the llvm::any_of() call.
