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.
|
|
; NOTE: Darwin PPC asm syntax is not yet supported by PPCAsmParser,
|
|
; so this test case uses ELF PPC asm syntax to produce a mach-o object.
|
|
; Once PPCAsmParser supports darwin asm syntax, this test case should
|
|
; be updated accordingly.
