llvm-mirror/test/CodeGen/PowerPC/hello-reloc.s
David Fang 772a101ff0 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

; 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.
