Implement x86 support for @llvm.prefetch. It corresponds to prefetcht{0\|1\|2} and prefetchnta instructions. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@48042 91177308-0d34-0410-b5e6-96231b3b80d8 2008-03-08 00:58:38 +00:00

Add one more argument to the prefetch intrinsic to indicate whether it's a data or instruction cache access. Update the targets to match it and also teach autoupgrade. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@132976 91177308-0d34-0410-b5e6-96231b3b80d8 2011-06-14 04:58:37 +00:00			`tail call void @llvm.prefetch( i8* %ptr, i32 0, i32 1, i32 1 )`
