Get it if you need to 31 do some serious hacking on this code. 32 33 Another reference: 34 "Peering Inside the PE: A Tour of the Win32 Portable Executable 35 File Format", MSJ 1994, Volume 9. 36 37 The *sole* difference between the pe format and the pei format is that the 38 latter has an MSDOS 2.0 .exe header on the front that prints the message 39 "This app must be run under Windows." (or some such). 40 (FIXME: Whether that statement is *really* true or not is unknown. 41 Are there more subtle differences between pe and pei formats? 42 For now assume there aren't. If you find one, then for God sakes 43 document it here!) 44 45 The Microsoft docs use the word "image" instead of "executable" because 46 the former can also refer to a DLL (shared library). Confusion can arise 47 because the `i' in `pei' also refers to "image". The `pe' format can 48 also create images (i.e. executables), it's just that to run on a win32 49 system you need to use the pei format. 50 51 FIXME: Please add more docs here so the next poor fool that has to hack 52 on this code has a chance of getting something accomplished without 53 wasting too much time. */ 54 55 /* This expands into COFF_WITH_pe or COFF_WITH_pep depending on whether 56 we're compiling for straight PE or PE+. */ 57 #define COFF_WITH_XX 58 59 #include "bfd.h" 60 #include "sysdep.h" 61 #include "libbfd.h" 62 #include "coff/internal.h" 63 64 /* NOTE: it's strange to be including an architecture specific header 65 in what's supposed to be general (to PE/PEI) code.
