[PowerPC] Add assembler parser This adds assembler parser support to the PowerPC back end. The parser will run for any powerpc-*-* and powerpc64-*-* triples, but was tested only on 64-bit Linux. The supported syntax is intended to be compatible with the GNU assembler. The parser does not yet support all PowerPC instructions, but it does support anything that is generated by LLVM itself. There is no support for testing restricted instruction sets yet, i.e. the parser will always accept any instructions it knows, no matter what feature flags are given. Instruction operands will be checked for validity and errors generated. (Error handling in general could still be improved.) The patch adds a number of test cases to verify instruction and operand encodings. The tests currently cover all instructions from the following PowerPC ISA v2.06 Book I facilities: Branch, Fixed-point, Floating-Point, and Vector. Note that a number of these instructions are not yet supported by the back end; they are marked with FIXME. A number of follow-on check-ins will add extra features. When they are all included, LLVM passes all tests (including bootstrap) when using clang -cc1as as the system assembler. llvm-svn: 181050

Add a disassembler to the PowerPC backend The tests for the disassembler were adapted from the encoder tests, and for the most part, the output from the disassembler matches that encoder-test inputs. There are some places where more-informative mnemonics could be produced (notably for the branch instructions), and those cases are noted in the tests with FIXMEs. Future work includes: - Generating more-informative mnemonics when possible (this may also be done in the printer). - Remove the dependence on positional "numbered" operand-to-variable mapping (for both encoding and decoding). - Internally using 64-bit instruction variants in 64-bit mode (if this turns out to matter). llvm-svn: 197693

[PowerPC] Skeletal FastISel support for 64-bit PowerPC ELF. 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. llvm-svn: 187399

Clean up a pile of hacks in our CMake build relating to TableGen. The first problem to fix is to stop creating synthetic *Table_gen targets next to all of the LLVM libraries. These had no real effect as CMake specifies that add_custom_command(OUTPUT ...) directives (what the 'tablegen(...)' stuff expands to) are implicitly added as dependencies to all the rules in that CMakeLists.txt. These synthetic rules started to cause problems as we started more and more heavily using tablegen files from *subdirectories* of the one where they were generated. Within those directories, the set of tablegen outputs was still available and so these synthetic rules added them as dependencies of those subdirectories. However, they were no longer properly associated with the custom command to generate them. Most of the time this "just worked" because something would get to the parent directory first, and run tablegen there. Once run, the files existed and the build proceeded happily. However, as more and more subdirectories have started using this, the probability of this failing to happen has increased. Recently with the MC refactorings, it became quite common for me when touching a large enough number of targets. To add insult to injury, several of the backends *tried* to fix this by adding explicit dependencies back to the parent directory's tablegen rules, but those dependencies didn't work as expected -- they weren't forming a linear chain, they were adding another thread in the race. This patch removes these synthetic rules completely, and adds a much simpler function to declare explicitly that a collection of tablegen'ed files are referenced by other libraries. From that, we can add explicit dependencies from the smaller libraries (such as every architectures Desc library) on this and correctly form a linear sequence. All of the backends are updated to use it, sometimes replacing the existing attempt at adding a dependency, sometimes adding a previously missing dependency edge. Please let me know if this causes any problems, but it fixes a rather persistent and problematic source of build flakiness on our end. llvm-svn: 136023

Add the PPCCTRLoops pass: a PPC machine-code-level optimization pass to form CTR-based loop branching code. This pass is derived from the Hexagon HardwareLoops pass. The only significant enhancement over the Hexagon pass is that PPCCTRLoops will also attempt to delete the replaced add and compare operations if they are no longer otherwise used. Also, invalid preheader DebugLoc is not used. llvm-svn: 158204

PPC64: Constant initializers with dynamic relocations go in .data.rel.ro. This fixes warning messages observed in the oggenc application test in projects/test-suite. Special handling is needed for the 64-bit PowerPC SVR4 ABI when a constant is initialized with a pointer to a function in a shared library. Because a function address is implemented as the address of a function descriptor, the use of copy relocations can lead to problems with initialization. GNU ld therefore replaces copy relocations with dynamic relocations to be resolved by the dynamic linker. This means the constant cannot reside in the read-only data section, but instead belongs in .data.rel.ro, which is designed for constants containing dynamic relocations. The implementation creates a class PPC64LinuxTargetObjectFile inheriting from TargetLoweringObjectFileELF, which behaves like its parent except to place constants of this sort into .data.rel.ro. The test case is reduced from the oggenc application. llvm-svn: 181723
