PE dos_message
I was looking at dos_message and wondering why we have H_PUT_32
in _bfd_XXi_only_swap_filehdr_out but no H_GET_32 in pe_bfd_object_p.
On a big-endian machine this would result in scrambling the code and
strings constained in dos_message. Rather than fix the lack of
H_GET_32 in pe_bfd_object_p, I decided it doesn't make sense to store
dos_message internally as an array of ints.
include/
* coff/internal.h (struct internal_extra_pe_filehdr): Make
dos_message a char array.
* coff/msdos.h (struct external_DOS_hdr): Flatten dos_message.
* coff/pe.h (struct external_PEI_filehdr): Likewise.
bfd/
* libcoff-in.h (struct pe_tdata): Make dos_message a char array.
* libcoff.h: Regenerate.
* peXXigen.c (_bfd_XXi_only_swap_filehdr_out): memcpy dos_message
to output.
* peicode.h (pe_mkobject): Don't memset already zeroed pe_opthdr.
Tidy allocation of tdata.pe_obj_data. Set up dos_message from..
(default_dos_message): ..this. New static array.
