This adds intrinsics to allow access to all of the z13 vector instructions. Note that instructions whose semantics can be described by standard LLVM IR do not get any intrinsics. For each instructions whose semantics *cannot* (fully) be described, we define an LLVM IR target-specific intrinsic that directly maps to this instruction. For instructions that also set the condition code, the LLVM IR intrinsic returns the post-instruction CC value as a second result. Instruction selection will attempt to detect code that compares that CC value against constants and use the condition code directly instead. Based on a patch by Richard Sandiford. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@236527 91177308-0d34-0410-b5e6-96231b3b80d8
