------------------------------------------------------------------------ r214670 | spatel | 2014-08-03 15:48:23 -0700 (Sun, 03 Aug 2014) | 8 lines fix for PR20354 - Miscompile of fabs due to vectorization This is intended to be the minimal change needed to fix PR20354 ( http://llvm.org/bugs/show_bug.cgi?id=20354 ). The check for a vector operation was wrong; we need to check that the fabs itself is not a vector operation. This patch will not generate the optimal code. A constant pool load and 'and' op will be generated instead of just returning a value that we can calculate in advance (as we do for the scalar case). I've put a 'TODO' comment for that here and expect to have that patch ready soon. There is a very similar optimization that we can do in visitFNEG, so I've put another 'TODO' there and expect to have another patch for that too. ------------------------------------------------------------------------ git-svn-id: https://llvm.org/svn/llvm-project/llvm/branches/release_35@215428 91177308-0d34-0410-b5e6-96231b3b80d8 |
