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

| 86 | |

| 89 | asm (".ascii \"-export:adef\""); |
| 90 | |

| 92 | { |
| 93 | printf("hello from the dll %s\n",s); |
| 94 | } |
| 95 | |
| 96 | bdef(char *s) |
| 97 | { |
| 98 | printf("hello from the dll and the other entry point %s\n",s); |
| 99 | } |
| 100 | |
| 101 | file2.c: |
| 102 | asm (".section .drectve"); |
| 103 | asm (".ascii \"-export:cdef\""); |
| 104 | asm (".ascii \"-export:ddef\""); |
| 105 | cdef(char *s) |
| 106 | { |
| 107 | printf("hello from the dll %s\n",s); |

| 163 | /* .idata section description |
| 164 | |
| 165 | The .idata section is the import table. It is a collection of several |
| 166 | subsections used to keep the pieces for each dll together: .idata$[234567]. |
| 167 | IE: Each dll's .idata$2's are catenated together, each .idata$3's, etc. |
| 168 | |
| 169 | .idata$2 = Import Directory Table |
| 170 | = array of IMAGE_IMPORT_DESCRIPTOR's. |
| 171 | |
| 172 | DWORD Characteristics; - pointer to .idata$4 |
| 173 | DWORD TimeDateStamp; - currently always 0 |
| 174 | DWORD ForwarderChain; - currently always 0 |
| 175 | DWORD Name; - pointer to dll's name |
| 176 | PIMAGE_THUNK_DATA FirstThunk; - pointer to .idata$5 |
| 177 | |
| 178 | .idata$3 = null terminating entry for .idata$2. |
| 179 | |
| 180 | .idata$4 = Import Lookup Table |
| 181 | = array of array of pointers to hint name table. |
| 182 | There is one for each dll being imported from, and each dll's set is |
| 183 | terminated by a trailing NULL. |
| 184 | |
| 185 | .idata$5 = Import Address Table |
| 186 | = array of array of pointers to hint name table. |
| 187 | There is one for each dll being imported from, and each dll's set is |
| 188 | terminated by a trailing NULL. |
| 189 | Initially, this table is identical to the Import Lookup Table. However, |
| 190 | at load time, the loader overwrites the entries with the address of the |
| 191 | function. |
| 192 | |
| 193 | .idata$6 = Hint Name Table |
| 194 | = Array of { short, asciz } entries, one for each imported function. |
| 195 | The `short' is the function's ordinal number. |
| 196 | |
| 197 | .idata$7 = dll name (eg: "kernel32.dll"). (.idata$6 for ppc) |
