This is the first of many upcoming patches for PowerPC fast instruction selection support. This patch implements the minimum necessary for a functional (but extremely limited) FastISel pass. It allows the table-generated portions of the selector to be created and used, but in most cases selection will fall back to the DAG selector. None of the block terminator instructions are implemented yet, and most interesting instructions require some special handling. Therefore there aren't any new test cases with this patch. There will be quite a few tests coming with future patches. This patch adds the make/CMake support for the new code (including tablegen -gen-fast-isel) and creates the FastISel object for PPC64 ELF only. It instantiates the necessary virtual functions (TargetSelectInstruction, TargetMaterializeConstant, TargetMaterializeAlloca, tryToFoldLoadIntoMI, and FastLowerArguments), but of these, only TargetMaterializeConstant contains any useful implementation. This is present since the table-generated code requires the ability to materialize integer constants for some instructions. This patch has been tested by building and running the projects/test-suite code with -O0. All tests passed with the exception of a couple of long-running tests that time out using -O0 code generation. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@187399 91177308-0d34-0410-b5e6-96231b3b80d8
