## Check how the PointerToRawData field is set for empty sections.
##
## Some tools may leave it set to a nonzero value, while others
## set it to zero. Currently, the LLVM MC layer produces a .data
## section with a nonzero PointerToRawData value, even if no
## .data section needs to be emitted. Other tools, such as yaml2obj
## writes a zero field if there's no data.
##
## When llvm-objcopy copies object files, it either needs to
## update the value to a valid value (within the bounds of the
## file, even if the section is empty) or zero. Some tools
## (such as obj2yaml or llvm-objcopy) can error out if the value
## is out of bounds.
##
## Check that our input file has got a nonzero field, and that
## it is set to zero after a run with llvm-objcopy.
