26 | BFD tries to maintain as much symbol information as it can when | |
27 | it moves information from file to file. BFD passes information | |
28 | to applications though the <<asymbol>> structure. When the | |
29 | application requests the symbol table, BFD reads the table in | |
30 | the native form and translates parts of it into the internal | |
31 | format. To maintain more than the information passed to | |
32 | applications, some targets keep some information ``behind the | |
33 | scenes'' in a structure only the particular back end knows | |
34 | about. For example, the coff back end keeps the original | |
35 | symbol table structure as well as the canonical structure when | |
36 | a BFD is read in. On output, the coff back end can reconstruct | |
37 | the output symbol table so that no information is lost, even | |
38 | information unique to coff which BFD doesn't know or | |
39 | understand. If a coff symbol table were read, but were written | |
40 | through an a.out back end, all the coff specific information | |
41 | would be lost. The symbol table of a BFD | |
42 | is not necessarily read in until a canonicalize request is | |
43 | made. Then the BFD back end fills in a table provided by the | |
44 | application with pointers to the canonical information. To | |
45 | output symbols, the application provides BFD with a table of | |
46 | pointers to pointers to <<asymbol>>s. This allows applications | |
47 | like the linker to output a symbol as it was read, since the ``behind | |
48 | the scenes'' information will be still available. | |

60 | Reading symbols | |
61 | ||
62 | There are two stages to reading a symbol table from a BFD: | |
63 | allocating storage, and the actual reading process. This is an | |
64 | excerpt from an application which reads the symbol table: | |
65 | ||
07d6d2b8 AM |
66 | | long storage_needed; |
67 | | asymbol **symbol_table; | |
68 | | long number_of_symbols; | |

252b5132 | 70 | | |
07d6d2b8 | 71 | | storage_needed = bfd_get_symtab_upper_bound (abfd); |
252b5132 RH |
72 | | |
73 | | if (storage_needed < 0) | |
74 | | FAIL | |
75 | | | |
07d6d2b8 AM |
76 | | if (storage_needed == 0) |
77 | | return; | |
68ffbac6 | 78 | | |
07d6d2b8 AM |
79 | | symbol_table = xmalloc (storage_needed); |
80 | | ... | |
81 | | number_of_symbols = | |
82 | | bfd_canonicalize_symtab (abfd, symbol_table); | |
252b5132 RH |

86 | | | |
07d6d2b8 AM |
87 | | for (i = 0; i < number_of_symbols; i++) |
88 | | process_symbol (symbol_table[i]); | |
252b5132 RH |
89 | |
90 | All storage for the symbols themselves is in an objalloc | |
91 | connected to the BFD; it is freed when the BFD is closed. | |

96 | Writing symbols | |
97 | ||
98 | Writing of a symbol table is automatic when a BFD open for | |
99 | writing is closed. The application attaches a vector of | |
100 | pointers to pointers to symbols to the BFD being written, and | |
101 | fills in the symbol count. The close and cleanup code reads | |
102 | through the table provided and performs all the necessary | |
103 | operations. The BFD output code must always be provided with an | |
104 | ``owned'' symbol: one which has come from another BFD, or one | |
105 | which has been created using <<bfd_make_empty_symbol>>. Here is an | |
106 | example showing the creation of a symbol table with only one element: | |
107 | ||
07d6d2b8 AM |
108 | | #include "sysdep.h" |
109 | | #include "bfd.h" | |
110 | | int main (void) | |
111 | | { | |
112 | | bfd *abfd; | |
113 | | asymbol *ptrs[2]; | |
114 | | asymbol *new; | |
252b5132 | 115 | | |
07d6d2b8 AM |
116 | | abfd = bfd_openw ("foo","a.out-sunos-big"); |
117 | | bfd_set_format (abfd, bfd_object); | |
118 | | new = bfd_make_empty_symbol (abfd); | |
119 | | new->name = "dummy_symbol"; | |
120 | | new->section = bfd_make_section_old_way (abfd, ".text"); | |
121 | | new->flags = BSF_GLOBAL; | |
122 | | new->value = 0x12345; | |
252b5132 | 123 | | |
07d6d2b8 AM |
124 | | ptrs[0] = new; |
125 | | ptrs[1] = 0; | |
252b5132 | 126 | | |
07d6d2b8 AM |
127 | | bfd_set_symtab (abfd, ptrs, 1); |
128 | | bfd_close (abfd); | |
129 | | return 0; | |
130 | | } | |
252b5132 | 131 | | |

7dee875e | 136 | Many formats cannot represent arbitrary symbol information; for |
07d6d2b8 | 137 | instance, the <<a.out>> object format does not allow an |
7dee875e | 138 | arbitrary number of sections. A symbol pointing to a section |
252b5132 RH |
139 | which is not one of <<.text>>, <<.data>> or <<.bss>> cannot |
140 | be described. | |

145 | Mini Symbols | |
146 | ||
147 | Mini symbols provide read-only access to the symbol table. | |
148 | They use less memory space, but require more time to access. | |
149 | They can be useful for tools like nm or objdump, which may | |
150 | have to handle symbol tables of extremely large executables. | |
151 | ||
152 | The <<bfd_read_minisymbols>> function will read the symbols | |
153 | into memory in an internal form. It will return a <<void *>> | |
154 | pointer to a block of memory, a symbol count, and the size of | |
155 | each symbol. The pointer is allocated using <<malloc>>, and | |
156 | should be freed by the caller when it is no longer needed. | |
157 | ||
158 | The function <<bfd_minisymbol_to_symbol>> will take a pointer | |
159 | to a minisymbol, and a pointer to a structure returned by | |
160 | <<bfd_make_empty_symbol>>, and return a <<asymbol>> structure. | |
161 | The return value may or may not be the same as the value from | |
162 | <<bfd_make_empty_symbol>> which was passed in. | |
