Get it if you need to 32 do some serious hacking on this code. 33 34 Another reference: 35 "Peering Inside the PE: A Tour of the Win32 Portable Executable 36 File Format", MSJ 1994, Volume 9. 37 38 The *sole* difference between the pe format and the pei format is that the 39 latter has an MSDOS 2.0 .exe header on the front that prints the message 40 "This app must be run under Windows." (or some such). 41 (FIXME: Whether that statement is *really* true or not is unknown. 42 Are there more subtle differences between pe and pei formats? 43 For now assume there aren't. If you find one, then for God sakes 44 document it here!) 45 46 The Microsoft docs use the word "image" instead of "executable" because 47 the former can also refer to a DLL (shared library). Confusion can arise 48 because the `i' in `pei' also refers to "image". The `pe' format can 49 also create images (i.e. executables), it's just that to run on a win32 50 system you need to use the pei format. 51 52 FIXME: Please add more docs here so the next poor fool that has to hack 53 on this code has a chance of getting something accomplished without 54 wasting too much time. */ 55 56 /* This expands into COFF_WITH_pe, COFF_WITH_pep, or COFF_WITH_pex64 57 depending on whether we're compiling for straight PE or PE+. */ 58 #define COFF_WITH_XX 59 60 #include "sysdep.h" 61 #include "bfd.h" 62 #include "libbfd.h" 63 #include "coff/internal.h" 64 #include "bfdver.h" 65 #include "libiberty.h" 66 #ifdef HAVE_WCHAR_H 67 #include <wchar.h> 68 #endif 69 #ifdef HAVE_WCTYPE_H 70 #include <wctype.h> 71 #endif 72 73 /* NOTE: it's strange to be including an architecture specific header 74 in what's supposed to be general (to PE/PEI) code.
