llvm-6502/test/MC/ARM/elf-reloc-01.ll
Rafael Espindola f194367792 Update tests to not be as dependent on section numbers.
Many of these predate llvm-readobj. With elf-dump we had to match
a relocation to symbol number and symbol number to symbol name or
section number.

;; Ensure no regression on ARM/gcc compatibility for
;; emitting explicit symbol relocs for nonexternal symbols
;; versus section symbol relocs (with offset) -
;;
;; Default llvm behavior is to emit as section symbol relocs nearly

;; Tests that reloc to _MergedGlobals show up as explicit symbol reloc
