R600: Add failing testcases. These are reduced from assert in the OpenCV CvtColor8u.BGR5652GRAY test. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@210969 91177308-0d34-0410-b5e6-96231b3b80d8 2014-06-14 04:26:09 +00:00			`; RUN: llc -march=r600 -mcpu=SI < %s`
R600/SI: Store constant initializer data in constant memory This implements a solution for constant initializers suggested by Vadim Girlin, where we store the data after the shader code and then use the S_GETPC instruction to compute its address. This saves use the trouble of creating a new buffer for constant data and then having to pass the pointer to the kernel via user SGPRs or the input buffer. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@213530 91177308-0d34-0410-b5e6-96231b3b80d8 2014-07-21 14:01:14 +00:00			`; CHECK: S_ENDPGM`
