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)
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.
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.
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.
41 A DEF file contains any number of the following commands:
44 NAME <name> [ , <base> ]
45 The result is going to be <name>.EXE
47 LIBRARY <name> [ , <base> ]
48 The result is going to be <name>.DLL
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>.
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.
65 DESCRIPTION <string>
66 Puts <string> into output .exp file in the .rdata section
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.
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.
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.
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.
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.
97 Example:
99 file1.c:
100 asm (".section .drectve");
101 asm (".ascii \"-export:adef\"");
103 void adef (char * s)
105 printf ("hello from the dll %s\n", s);
108 void bdef (char * s)
110 printf ("hello from the dll and the other entry point %s\n", s);
113 file2.c:
114 asm (".section .drectve");
115 asm (".ascii \"-export:cdef\"");
116 asm (".ascii \"-export:ddef\"");
118 void cdef (char * s)
120 printf ("hello from the dll %s\n", s);
123 void ddef (char * s)
125 printf ("hello from the dll and the other entry point %s\n", s);
128 int printf (void)
130 return 9;
133 themain.c:
134 int main (void)
136 cdef ();
137 return 0;
140 thedll.def
142 LIBRARY thedll
143 HEAPSIZE 0x40000, 0x2000
144 EXPORTS bdef @ 20
145 cdef @ 30 NONAME
147 SECTIONS donkey READ WRITE

154 # Optional: put the dll objects into a library

175 This example can be extended if relocations are needed in the DLL:

179 gcc -c file1.c file2.c themain.c
181 # Run this tool over the DLL's .def file and generate an imports file.

190 # Run this tool over the DLL's .def file and generate an exports file
191 # which includes the relocations from the base file.
193 dlltool --def thedll.def --base-file themain.base --output-exp thedll.exp
195 # Build the dll with file1.o, file2.o and the export table
197 ld -o thedll.dll thedll.exp file1.o file2.o */
199 /* .idata section description
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.
205 .idata$2 = Import Directory Table
206 = array of IMAGE_IMPORT_DESCRIPTOR's.
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
214 .idata$3 = null terminating entry for .idata$2.
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.
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.
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.
233 .idata$7 = dll name (eg: "kernel32.dll"). (.idata$6 for ppc). */

1065 In defparse.y we have to accept import declarations which follow

1068 <func_name_in_app> = <dll_name>.<number>
1069 <dll_name>.<func_name_in_dll>

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.
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
