* peigen.c (_bfd_pei_swap_aouthdr_out): Pass ImageBase to
|
||||
add_data_entry. DataDirectory virtual address is relative.
|
||||
(pe_print_idata): Account for relative DataDirectory virtual
|
||||
addresses. Don't trash datasize inside POWERPC_LE_PE code.
|
||||
(pe_print_edata): Similarly.
|
||||
|
||||
From Szabolcs Szakacsits <szaka@F-Secure.com>
|
||||
* peigen.c (dir_names): Add Delay Import Directory.
|
||||
(pe_print_idata): Always search for bfd section containing
|
||||
idata address rather than looking up section name. Print this
|
||||
section name rather than .idata.
|
||||
(pe_print_edata): Similarly. Also print some fields as %08lx.
|
||||
(_bfd_pe_print_private_bfd_data_common): Print Reserved1 field as
|
||||
Win32Version.
