(16) into certain areas of the SPARC V9 back-end. I'm fairly sure the US IIIi's dcache has 32-byte lines, so I'm not sure where the 16 came from. However, in the interest of not breaking things any more than they already are, I'm going to leave the constant alone. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@12043 91177308-0d34-0410-b5e6-96231b3b80d8
