initial draft of PPCMachObjectWriter.cpp this records relocation entries in the mach-o object file for PIC code generation. tested on powerpc-darwin8, validated against darwin otool -rvV git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@188004 91177308-0d34-0410-b5e6-96231b3b80d8

; This tests for the basic implementation of PPCMachObjectWriter.cpp,
; which is responsible for writing mach-o relocation entries for (PIC)
; PowerPC objects.

[Powerpc darwin] AsmParser Base implementation. This is a base implementation of the powerpc-apple-darwin asm parser dialect. * Enables infrastructure (essentially isDarwin()) and fixes up the parsing of asm directives to separate out ELF and MachO/Darwin additions. * Enables parsing of {r,f,v}XX as register identifiers. * Enables parsing of lo16() hi16() and ha16() as modifiers. The changes to the test case are from David Fang (fangism). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@197324 91177308-0d34-0410-b5e6-96231b3b80d8

llvm-readobj: fix MachO relocatoin printing a bit. There were two issues here: 1. At the very least, scattered relocations cannot use the same code to determine the corresponding symbol being referred to. For some reason we pretend there is no symbol, even when one actually exists in the symtab, so to match this behaviour getRelocationSymbol should simply return symbols_end for scattered relocations. 2. Printing "-" when we can't get a symbol (including the scattered case, but not exclusively), isn't that helpful. In both cases there *is* interesting information in that field, so we should print it. As hex will do. Small part of rdar://problem/17553104 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@212332 91177308-0d34-0410-b5e6-96231b3b80d8
