intrinsics. The second instruction(s) to be handled are the vector versions of count set bits (ctpop). The changes here are to clang so that it generates a target independent vector ctpop when it sees an ARM dependent vector bits set count. The changes in llvm are to match the target independent vector ctpop and in VMCore/AutoUpgrade.cpp to update any existing bc files containing ARM dependent vector pop counts with target-independent ctpops. There are also changes to an existing test case in llvm for ARM vector count instructions and to a test for the bitcode upgrade. <rdar://problem/11892519> There is deliberately no test for the change to clang, as so far as I know, no consensus has been reached regarding how to test neon instructions in clang; q.v. <rdar://problem/8762292> git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@160410 91177308-0d34-0410-b5e6-96231b3b80d8
