MC: Add support for treating $ as a reference to the PC The binutils assembler supports a mode called DOLLAR_DOT which treats the dollar sign token as a reference to the current program counter if the dollar sign doesn't precede a constant or identifier. This commit adds a new MCAsmInfo flag stating whether or not a given target supports this interpretation of the dollar sign token; by default, this flag is not enabled. Further, enable this flag for PPC. The system assembler for AIX and binutils both support using the dollar sign in this manner. This fixes PR17353. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@191368 91177308-0d34-0410-b5e6-96231b3b80d8

[PowerPC] Accept 17-bit signed immediates for addis The assembler currently strictly verifies that immediates for s16imm operands are in range (-32768 ... 32767). This matches the behaviour of the GNU assembler, with one exception: gas allows, as a special case, operands in an extended range (-65536 .. 65535) for the addis instruction only (and its extended mnemonic lis). The main reason for this seems to be to allow using unsigned 16-bit operands for lis, e.g. like lis %r1, 0xfedc. Since this has been supported by gas for a long time, and assembler source code seen "in the wild" actually exploits this feature, this patch adds equivalent support to LLVM for compatibility reasons. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@184946 91177308-0d34-0410-b5e6-96231b3b80d8

[PowerPC] Support absolute branches There is currently only limited support for the "absolute" variants of branch instructions. This patch adds support for the absolute variants of all branches that are currently otherwise supported. This requires adding new fixup types so that the correct variant of relocation type can be selected by the object writer. While the compiler will continue to usually choose the relative branch variants, this will allow the asm parser to fully support the absolute branches, with either immediate (numerical) or symbolic target addresses. No change in code generation intended. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@184721 91177308-0d34-0410-b5e6-96231b3b80d8

[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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@181050 91177308-0d34-0410-b5e6-96231b3b80d8
