- Add appropriate TableGen patterns for fadd, fsub, fmul. - Add .f32 as the PTX type for the LLVM float type. - Allow parameters, return values, and global variable declarations to accept the float type. - Add appropriate test cases. Patch by Justin Holewinski git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@126636 91177308-0d34-0410-b5e6-96231b3b80d8
