2012-07-18More replacing of target-dependent intrinsics with target-indepdent Joel Jones
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

2012-07-17Allow for customized graph edge pruning in PostOrderIterator.hJakob Stoklund Olesen
Make it possible to prune individual graph edges from a post-order traversal by specializing the po_iterator_storage template. Previously, it was only possible to prune full graph nodes. Edge pruning makes it possible to remove loop back-edges, for example. Also replace the existing DFSetTraits customization hook with a po_iterator_storage method for observing the post-order. DFSetTraits was only used by LoopIterator.h which now provides a po_iterator_storage specialization. Thanks to Sean and Chandler for reviewing. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@160366 91177308-0d34-0410-b5e6-96231b3b80d8

Define a 'null_frag' SDPatternOperator node, which if referenced in an instruction Pattern, results in the pattern being collapsed to be as-if '[]' had been specified instead. This allows supporting a multiclass definition where some instaniations have ISel patterns associated and others do not. For example, multiclass myMulti<RegisterClass rc, SDPatternOperator OpNode = null_frag> { def _x : myI<(outs rc:), (ins rc:), []>; def _r : myI<(outs rc:), (ins rc:), [(set rc:, (OpNode rc:))]>; } defm foo : myMulti<GRa, not>; defm bar : myMulti<GRb>; git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@160333 91177308-0d34-0410-b5e6-96231b3b80d8
