These instructions compare two floating point values and return an integer true (-1) or false (0) value. When compiling code generated by the Mesa GLSL frontend, the SET*_DX10 instructions save us four instructions for most branch decisions that use floating-point comparisons. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@174609 91177308-0d34-0410-b5e6-96231b3b80d8
