23 | * unexec.c - Convert a running program into an a.out file. | |
24 | * | |
25 | * Author: Spencer W. Thomas | |
26 | * Computer Science Dept. | |
27 | * University of Utah | |
28 | * Date: Tue Mar 2 1982 | |
29 | * Modified heavily since then. | |
30 | * | |
31 | * Synopsis: | |
32 | * unexec (new_name, a_name, data_start, bss_start, entry_address) | |
33 | * char *new_name, *a_name; | |
34 | * unsigned data_start, bss_start, entry_address; | |
35 | * | |
36 | * Takes a snapshot of the program and makes an a.out format file in the | |
37 | * file named by the string argument new_name. | |
38 | * If a_name is non-NULL, the symbol table will be taken from the given file. | |
39 | * On some machines, an existing a_name file is required. | |
40 | * | |
41 | * The boundaries within the a.out file may be adjusted with the data_start | |
42 | * and bss_start arguments. Either or both may be given as 0 for defaults. | |
43 | * | |
44 | * Data_start gives the boundary between the text segment and the data | |
45 | * segment of the program. The text segment can contain shared, read-only | |
46 | * program code and literal data, while the data segment is always unshared | |
47 | * and unprotected. Data_start gives the lowest unprotected address. | |
48 | * The value you specify may be rounded down to a suitable boundary | |
49 | * as required by the machine you are using. | |
50 | * | |
51 | * Specifying zero for data_start means the boundary between text and data | |
52 | * should not be the same as when the program was loaded. | |
53 | * If NO_REMAP is defined, the argument data_start is ignored and the | |
54 | * segment boundaries are never changed. | |
55 | * | |
56 | * Bss_start indicates how much of the data segment is to be saved in the | |
57 | * a.out file and restored when the program is executed. It gives the lowest | |
58 | * unsaved address, and is rounded up to a page boundary. The default when 0 | |
59 | * is given assumes that the entire data segment is to be stored, including | |
60 | * the previous data and bss as well as any additional storage allocated with | |
61 | * break (2). | |
62 | * | |
63 | * The new file is set up to start at entry_address. | |
64 | * | |
65 | * If you make improvements I'd like to get them too. | |
66 | * harpo!utah-cs!thomas, thomas@Utah-20 | |

73 | ||
74 | /* There are several compilation parameters affecting unexec: | |
75 | ||
76 | * COFF | |
77 | ||
78 | Define this if your system uses COFF for executables. | |
265a9e55 | 79 | |
7dd63af1 RS |
80 | * NO_REMAP |
81 | ||
82 | Define this if you do not want to try to save Emacs's pure data areas | |
83 | as part of the text segment. | |
84 | ||
85 | Saving them as text is good because it allows users to share more. | |
86 | ||
87 | However, on machines that locate the text area far from the data area, | |
88 | the boundary cannot feasibly be moved. Such machines require | |
89 | NO_REMAP. | |
90 | ||
91 | Also, remapping can cause trouble with the built-in startup routine | |
92 | /lib/crt0.o, which defines `environ' as an initialized variable. | |
93 | Dumping `environ' as pure does not work! So, to use remapping, | |
94 | you must write a startup routine for your machine in Emacs's crt0.c. | |
95 | If NO_REMAP is defined, Emacs uses the system's crt0.o. | |
96 | ||
97 | * SECTION_ALIGNMENT | |
98 | ||
99 | Some machines that use COFF executables require that each section | |
100 | start on a certain boundary *in the COFF file*. Such machines should | |
101 | define SECTION_ALIGNMENT to a mask of the low-order bits that must be | |
102 | zero on such a boundary. This mask is used to control padding between | |
103 | segments in the COFF file. | |
104 | ||
105 | If SECTION_ALIGNMENT is not defined, the segments are written | |
106 | consecutively with no attempt at alignment. This is right for | |
107 | unmodified system V. | |
108 | ||
109 | * SEGMENT_MASK | |
110 | ||
111 | Some machines require that the beginnings and ends of segments | |
112 | *in core* be on certain boundaries. For most machines, a page | |
113 | boundary is sufficient. That is the default. When a larger | |
114 | boundary is needed, define SEGMENT_MASK to a mask of | |
115 | the bits that must be zero on such a boundary. | |
116 | ||
117 | * A_TEXT_OFFSET(HDR) | |
118 | ||
119 | Some machines count the a.out header as part of the size of the text | |
120 | segment (a_text); they may actually load the header into core as the | |
121 | first data in the text segment. Some have additional padding between | |
122 | the header and the real text of the program that is counted in a_text. | |
123 | ||
124 | For these machines, define A_TEXT_OFFSET(HDR) to examine the header | |
125 | structure HDR and return the number of bytes to add to `a_text' | |
126 | before writing it (above and beyond the number of bytes of actual | |
127 | program text). HDR's standard fields are already correct, except that | |
128 | this adjustment to the `a_text' field has not yet been made; | |
129 | thus, the amount of offset can depend on the data in the file. | |
177c0ea7 | 130 | |
7dd63af1 RS |
131 | * A_TEXT_SEEK(HDR) |
132 | ||
133 | If defined, this macro specifies the number of bytes to seek into the | |
2d30a233 | 134 | a.out file before starting to write the text segment. |
7dd63af1 | 135 | |
7dd63af1 RS |
136 | * ADJUST_EXEC_HEADER |
137 | ||
138 | This macro can be used to generate statements to adjust or | |
139 | initialize nonstandard fields in the file header | |
140 | ||
141 | * ADDR_CORRECT(ADDR) | |
142 | ||
143 | Macro to correct an int which is the bit pattern of a pointer to a byte | |
144 | into an int which is the number of a byte. | |
145 | ||
146 | This macro has a default definition which is usually right. | |
147 | This default definition is a no-op on most machines (where a | |
148 | pointer looks like an int) but not on all machines. | |
