This patch series adds support for the IBM z14 processor. This part includes: - Basic support for the new processor and its features. - Support for new instructions (except vector 32-bit float and 128-bit float). - CodeGen for new instructions, including new LLVM intrinsics. - Scheduler description for the new processor. - Detection of z14 as host processor. Support for the new 32-bit vector float and 128-bit vector float instructions is provided by separate patches. llvm-svn: 308194
