This allows us to continue processing the translation unit. Test case to come on the clang side because we need an inline asm diagnostics handler in place. rdar://13446483 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@180873 91177308-0d34-0410-b5e6-96231b3b80d8 Optimize away nop CONCAT_VECTOR nodes. 2013-05-01T19:18:51Z Nadav Rotem nrotem@apple.com 2013-05-01T19:18:51Z urn:sha1:b2ed5fac0693e949ffdbf45266f5d53839211b63 Optimize CONCAT_VECTOR nodes that merge EXTRACT_SUBVECTOR values that extract from the same vector. rdar://13402653 PR15866 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@180871 91177308-0d34-0410-b5e6-96231b3b80d8 Only pass 'returned' to target-specific lowering code when the value of entire register is guaranteed to be preserved. 2013-04-30T22:49:28Z Stephen Lin stephenwlin@gmail.com 2013-04-30T22:49:28Z urn:sha1:3484da9479a4daff3efc7febe004e1f4d69b3b4a git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@180825 91177308-0d34-0410-b5e6-96231b3b80d8 Temporarily revert "Change the informal convention of DBG_VALUE so that we can express a" 2013-04-30T22:35:14Z Adrian Prantl aprantl@apple.com 2013-04-30T22:35:14Z urn:sha1:86a87d9ba1faf153e0e6eaddfd3e95595c83bcb1 because it breaks some buildbots.

It used to be that a DBG_VALUE is a register-indirect value if the offset (operand 1) is nonzero. The new convention is that a DBG_VALUE is register-indirect if the first operand is a register and the second operand is an immediate. For plain registers use the combination reg, reg. rdar://problem/13658587 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@180816 91177308-0d34-0410-b5e6-96231b3b80d8 Re-write the address propagation code for pre-indexed loads/stores to take into account some previously misssed cases (PRE_DEC addressing mode, the offset and base address are swapped, etc).

The long term goal is to enable the backend to match a canonicalized pattern into a single instruction (e.g. vabs or pabs). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@180597 91177308-0d34-0410-b5e6-96231b3b80d8 Fix constant folding for one lane vector types.
