22 Most of this hacked by Steve Chamberlain,
25 PE/PEI rearrangement (and code added): Donn Terry
29 /* Hey look, some documentation [and in a place you expect to find it]!
31 The main reference for the pei format is "Microsoft Portable Executable
32 and Common Object File Format Specification 4.1". Get it if you need to
33 do some serious hacking on this code.
36 "Peering Inside the PE: A Tour of the Win32 Portable Executable
37 File Format", MSJ 1994, Volume 9.
39 The *sole* difference between the pe format and the pei format is that the
40 latter has an MSDOS 2.0 .exe header on the front that prints the message
41 "This app must be run under Windows." (or some such).
42 (FIXME: Whether that statement is *really* true or not is unknown.
43 Are there more subtle differences between pe and pei formats?
44 For now assume there aren't. If you find one, then for God sakes
47 The Microsoft docs use the word "image" instead of "executable" because
48 the former can also refer to a DLL (shared library). Confusion can arise
49 because the `i' in `pei' also refers to "image". The `pe' format can
50 also create images (i.e. executables), it's just that to run on a win32
51 system you need to use the pei format.
53 FIXME: Please add more docs here so the next poor fool that has to hack
54 on this code has a chance of getting something accomplished without
55 wasting too much time.
61 #include "coff/internal.h"
63 /* NOTE: it's strange to be including an architecture specific header
64 in what's supposed to be general (to PE/PEI) code. However, that's
65 where the definitions are, and they don't vary per architecture
66 within PE/PEI, so we get them from there. FIXME: The lack of
67 variance is an assumption which may prove to be incorrect if new
68 PE/PEI targets are created. */
69 #include "coff/i386.h"
75 /* FIXME: This file has various tests of POWERPC_LE_PE. Those tests
76 worked when the code was in peicode.h, but no longer work now that
77 the code is in peigen.c. PowerPC NT is said to be dead. If
78 anybody wants to revive the code, you will have to figure out how
79 to handle those issues. */
