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

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