PE/PEI rearrangement (and code added): Donn Terry Softway Systems, Inc. */ /* Hey look, some documentation [and in a place you expect to find it]! The main reference for the pei format is "Microsoft Portable Executable and Common Object File Format Specification 4.1". Get it if you need to do some serious hacking on this code. Another reference: "Peering Inside the PE: A Tour of the Win32 Portable Executable File Format", MSJ 1994, Volume 9. The *sole* difference between the pe format and the pei format is that the latter has an MSDOS 2.0 .exe header on the front that prints the message "This app must be run under Windows." (or some such). (FIXME: Whether that statement is *really* true or not is unknown. Are there more subtle differences between pe and pei formats? For now assume there aren't. If you find one, then for God sakes document it here!) The Microsoft docs use the word "image" instead of "executable" because the former can also refer to a DLL (shared library). Confusion can arise because the `i' in `pei' also refers to "image". The `pe' format can also create images (i.e. executables), it's just that to run on a win32 system you need to use the pei format. FIXME: Please add more docs here so the next poor fool that has to hack on this code has a chance of getting something accomplished without wasting too much time. */ /* This expands into COFF_WITH_pe, COFF_WITH_pep, or COFF_WITH_pex64 depending on whether we're compiling for straight PE or PE+. */ #define COFF_WITH_XX #include "sysdep.h" #include "bfd.h" #include "libbfd.h" #include "coff/internal.h" /* NOTE: it's strange to be including an architecture specific header in what's supposed to be general (to PE/PEI) code.
