44 /* This file turns a regular Windows PE image into a DLL. Because of
45 the complexity of this operation, it has been broken down into a
46 number of separate modules which are all called by the main function
47 at the end of this file. This function is not re-entrant and is
48 normally only called once, so static variables are used to reduce
49 the number of parameters and return values required.

53 /* Auto-import feature by Paul Sokolovsky
57 1. With this feature on, DLL clients can import variables from DLL
58 without any concern from their side (for example, without any source
61 2. This is done completely in bounds of the PE specification (to be fair,
62 there's a place where it pokes nose out of, but in practice it works).
63 So, resulting module can be used with any other PE compiler/linker.
65 3. Auto-import is fully compatible with standard import method and they
66 can be mixed together.
68 4. Overheads: space: 8 bytes per imported symbol, plus 20 for each
69 reference to it; load time: negligible; virtual/physical memory: should be
70 less than effect of DLL relocation, and I sincerely hope it doesn't affect
71 DLL sharability (too much).
75 The obvious and only way to get rid of dllimport insanity is to make client
76 access variable directly in the DLL, bypassing extra dereference. I.e.,
77 whenever client contains something like
81 address of dll_var in the command should be relocated to point into loaded
82 DLL. The aim is to make OS loader do so, and than make ld help with that.
83 Import section of PE made following way: there's a vector of structures
84 each describing imports from particular DLL. Each such structure points
85 to two other parallel vectors: one holding imported names, and one which
86 will hold address of corresponding imported name. So, the solution is
87 de-vectorize these structures, making import locations be sparse and
88 pointing directly into code. Before continuing, it is worth a note that,
89 while authors strives to make PE act ELF-like, there're some other people
90 make ELF act PE-like: elfvector, ;-) .
94 For each reference of data symbol to be imported from DLL (to set of which
95 belong symbols with name <sym>, if __imp_<sym> is found in implib), the
96 import fixup entry is generated. That entry is of type
97 IMAGE_IMPORT_DESCRIPTOR and stored in .idata$3 subsection. Each
98 fixup entry contains pointer to symbol's address within .text section
99 (marked with __fuN_<sym> symbol, where N is integer), pointer to DLL name
100 (so, DLL name is referenced by multiple entries), and pointer to symbol
101 name thunk. Symbol name thunk is singleton vector (__nm_th_<symbol>)
102 pointing to IMAGE_IMPORT_BY_NAME structure (__nm_<symbol>) directly
103 containing imported name. Here comes that "om the edge" problem mentioned
104 above: PE specification rambles that name vector (OriginalFirstThunk)
105 should run in parallel with addresses vector (FirstThunk), i.e. that they
106 should have same number of elements and terminated with zero. We violate
107 this, since FirstThunk points directly into machine code. But in practice,
108 OS loader implemented the sane way: it goes thru OriginalFirstThunk and
109 puts addresses to FirstThunk, not something else. It once again should be
110 noted that dll and symbol name structures are reused across fixup entries
111 and should be there anyway to support standard import stuff, so sustained
112 overhead is 20 bytes per reference. Other question is whether having several
113 IMAGE_IMPORT_DESCRIPTORS for the same DLL is possible. Answer is yes, it is
114 done even by native compiler/linker (libth32's functions are in fact reside
115 in windows9x kernel32.dll, so if you use it, you have two
116 IMAGE_IMPORT_DESCRIPTORS for kernel32.dll). Yet other question is whether
117 referencing the same PE structures several times is valid. The answer is why
118 not, prohibiting that (detecting violation) would require more work on
119 behalf of loader than not doing it.
