23/* This program allows you to build the files necessary to create
24 DLLs to run on a system which understands PE format image files.
25 (eg, Windows NT)
26
27 See "Peering Inside the PE: A Tour of the Win32 Portable Executable
28 File Format", MSJ 1994, Volume 9 for more information.
29 Also see "Microsoft Portable Executable and Common Object File Format,
30 Specification 4.1" for more information.
31
32 A DLL contains an export table which contains the information
33 which the runtime loader needs to tie up references from a
34 referencing program.
35
36 The export table is generated by this program by reading
37 in a .DEF file or scanning the .a and .o files which will be in the
38 DLL. A .o file can contain information in special ".drectve" sections
39 with export information.
40
41 A DEF file contains any number of the following commands:
42
43
44 NAME <name> [ , <base> ]
45 The result is going to be <name>.EXE
46
47 LIBRARY <name> [ , <base> ]
48 The result is going to be <name>.DLL
49
50 EXPORTS ( ( ( <name1> [ = <name2> ] )
51 | ( <name1> = <module-name> . <external-name>))
52 [ @ <integer> ] [ NONAME ] [CONSTANT] [DATA] ) *
53 Declares name1 as an exported symbol from the
54 DLL, with optional ordinal number <integer>.
55 Or declares name1 as an alias (forward) of the function <external-name>
56 in the DLL <module-name>.
57
58 IMPORTS ( ( <internal-name> = <module-name> . <integer> )
59 | ( [ <internal-name> = ] <module-name> . <external-name> )) *
60 Declares that <external-name> or the exported function whoes ordinal number
61 is <integer> is to be imported from the file <module-name>. If
62 <internal-name> is specified then this is the name that the imported
63 function will be refered to in the body of the DLL.
64
65 DESCRIPTION <string>
66 Puts <string> into output .exp file in the .rdata section
67
68 [STACKSIZE|HEAPSIZE] <number-reserve> [ , <number-commit> ]
69 Generates --stack|--heap <number-reserve>,<number-commit>
70 in the output .drectve section. The linker will
71 see this and act upon it.
72
73 [CODE|DATA] <attr>+
74 SECTIONS ( <sectionname> <attr>+ )*
75 <attr> = READ | WRITE | EXECUTE | SHARED
76 Generates --attr <sectionname> <attr> in the output
77 .drectve section. The linker will see this and act
78 upon it.
79
80
81 A -export:<name> in a .drectve section in an input .o or .a
82 file to this program is equivalent to a EXPORTS <name>
83 in a .DEF file.
84
85
86
87 The program generates output files with the prefix supplied
88 on the command line, or in the def file, or taken from the first
89 supplied argument.
90
91 The .exp.s file contains the information necessary to export
92 the routines in the DLL. The .lib.s file contains the information
93 necessary to use the DLL's routines from a referencing program.
94
95

98
99 file1.c:
100 asm (".section .drectve");
101 asm (".ascii \"-export:adef\"");

106 }
107
108 void bdef (char * s)
109 {
110 printf ("hello from the dll and the other entry point %s\n", s);
111 }
112
113 file2.c:
114 asm (".section .drectve");
115 asm (".ascii \"-export:cdef\"");
116 asm (".ascii \"-export:ddef\"");
117

119 {
120 printf ("hello from the dll %s\n", s);
121 }
122
123 void ddef (char * s)
124 {
125 printf ("hello from the dll and the other entry point %s\n", s);
126 }
127

199/* .idata section description
200
201 The .idata section is the import table. It is a collection of several
202 subsections used to keep the pieces for each dll together: .idata$[234567].
203 IE: Each dll's .idata$2's are catenated together, each .idata$3's, etc.
204
205 .idata$2 = Import Directory Table
206 = array of IMAGE_IMPORT_DESCRIPTOR's.
207
208 DWORD Import Lookup Table; - pointer to .idata$4
209 DWORD TimeDateStamp; - currently always 0
210 DWORD ForwarderChain; - currently always 0
211 DWORD Name; - pointer to dll's name
212 PIMAGE_THUNK_DATA FirstThunk; - pointer to .idata$5
213
214 .idata$3 = null terminating entry for .idata$2.
215
216 .idata$4 = Import Lookup Table
217 = array of array of pointers to hint name table.
218 There is one for each dll being imported from, and each dll's set is
219 terminated by a trailing NULL.
220
221 .idata$5 = Import Address Table
222 = array of array of pointers to hint name table.
223 There is one for each dll being imported from, and each dll's set is
224 terminated by a trailing NULL.
225 Initially, this table is identical to the Import Lookup Table. However,
226 at load time, the loader overwrites the entries with the address of the
227 function.
228
229 .idata$6 = Hint Name Table
230 = Array of { short, asciz } entries, one for each imported function.
231 The `short' is the function's ordinal number.
232
233 .idata$7 = dll name (eg: "kernel32.dll"). (.idata$6 for ppc). */

315
316 When IMPORT declarations are encountered in a .def file the
317 function import information is stored in a structure referenced by
318 the global variable IMPORT_LIST. The structure is a linked list
319 containing the names of the dll files each function is imported
320 from and a linked list of functions being imported from that dll
321 file. This roughly parallels the structure of the .idata section
322 in the PE object file.
323
324 The contents of .def file are interpreted from within the
325 process_def_file function. Every time an IMPORT declaration is
326 encountered, it is broken up into its component parts and passed to
327 def_import. IMPORT_LIST is initialized to NULL in function main. */

1065 In defparse.y we have to accept import declarations which follow
1066 any one of the following forms:

1068 <func_name_in_app> = <dll_name>.<number>
1069 <dll_name>.<func_name_in_dll>
1070 <dll_name>.<number>
1071 Furthermore, the dll's name may or may not end with ".dll", which
1072 complicates the parsing a little. Normally the dll's name is
1073 passed to def_import() in the "module" parameter, but when it ends
1074 with ".dll" it gets passed in "module" sans ".dll" and that needs
1075 to be reappended.
1076
1077 def_import gets five parameters:
1078 APP_NAME - the name of the function in the application, if
1079 present, or NULL if not present.
1080 MODULE - the name of the dll, possibly sans extension (ie, '.dll').
1081 DLLEXT - the extension of the dll, if present, NULL if not present.
1082 ENTRY - the name of the function in the dll, if present, or NULL.
1083 ORD_VAL - the numerical tag of the function in the dll, if present,
1084 or NULL. Exactly one of <entry> or <ord_val> must be
1085 present (i.e., not NULL). */
