38 | /* The ECOFF file format uses COFF style sections, but with a unique | |
39 | debugging format. We just build generic BFD sections since BFD | |
40 | knows how to write them out. The debugging format, however, we | |
41 | must construct here; all BFD knows at the moment is to write it out | |
42 | as a large block of data. | |
43 | ||
44 | We support both COFF style debugging and stabs debugging (the stabs | |
45 | symbols are encapsulated in COFF symbols). This should let us | |
46 | handle anything the compiler might throw at us. Parsing the COFF | |
47 | and stabs debugging information is similar to work done by COFF and | |
48 | a.out targets, but since the result is completely different the | |
49 | code is not shared. */ | |

51 | /* Here is a brief description of the MIPS ECOFF symbol table, by | |
52 | Michael Meissner. The MIPS symbol table has the following pieces: | |
53 | ||
54 | Symbolic Header | |
55 | | | |
56 | +-- Auxiliary Symbols | |
57 | | | |
58 | +-- Dense number table | |
59 | | | |
60 | +-- Optimizer Symbols | |
61 | | | |
62 | +-- External Strings | |
63 | | | |
64 | +-- External Symbols | |
65 | | | |
66 | +-- Relative file descriptors | |
67 | | | |
68 | +-- File table | |
69 | | | |
70 | +-- Procedure table | |
71 | | | |
72 | +-- Line number table | |
73 | | | |
74 | +-- Local Strings | |
75 | | | |
76 | +-- Local Symbols | |
77 | ||
78 | The symbolic header points to each of the other tables, and also | |
79 | contains the number of entries. It also contains a magic number | |
80 | and MIPS compiler version number, such as 2.0. | |
81 | ||
82 | The auxiliary table is a series of 32 bit integers, that are | |
83 | referenced as needed from the local symbol table. Unlike standard | |
84 | COFF, the aux. information does not follow the symbol that uses | |
85 | it, but rather is a separate table. In theory, this would allow | |
86 | the MIPS compilers to collapse duplicate aux. entries, but I've not | |
87 | noticed this happening with the 1.31 compiler suite. The different | |
88 | types of aux. entries are: | |
89 | ||
90 | 1) dnLow: Low bound on array dimension. | |
91 | ||
92 | 2) dnHigh: High bound on array dimension. | |
93 | ||
94 | 3) isym: Index to the local symbol which is the start of the | |
95 | function for the end of function first aux. entry. | |
96 | ||
97 | 4) width: Width of structures and bitfields. | |
98 | ||
99 | 5) count: Count of ranges for variant part. | |
100 | ||
101 | 6) rndx: A relative index into the symbol table. The relative | |
102 | index field has two parts: rfd which is a pointer into the | |
103 | relative file index table or ST_RFDESCAPE which says the next | |
104 | aux. entry is the file number, and index: which is the pointer | |
105 | into the local symbol within a given file table. This is for | |
106 | things like references to types defined in another file. | |
107 | ||
108 | 7) Type information: This is like the COFF type bits, except it | |
109 | is 32 bits instead of 16; they still have room to add new | |
110 | basic types; and they can handle more than 6 levels of array, | |
111 | pointer, function, etc. Each type information field contains | |
112 | the following structure members: | |
113 | ||
114 | a) fBitfield: a bit that says this is a bitfield, and the | |
115 | size in bits follows as the next aux. entry. | |
116 | ||
117 | b) continued: a bit that says the next aux. entry is a | |
118 | continuation of the current type information (in case | |
119 | there are more than 6 levels of array/ptr/function). | |
120 | ||
121 | c) bt: an integer containing the base type before adding | |
122 | array, pointer, function, etc. qualifiers. The | |
123 | current base types that I have documentation for are: | |
124 | ||
125 | btNil -- undefined | |
126 | btAdr -- address - integer same size as ptr | |
127 | btChar -- character | |
128 | btUChar -- unsigned character | |
129 | btShort -- short | |
130 | btUShort -- unsigned short | |
131 | btInt -- int | |
132 | btUInt -- unsigned int | |
133 | btLong -- long | |
134 | btULong -- unsigned long | |
135 | btFloat -- float (real) | |
136 | btDouble -- Double (real) | |
137 | btStruct -- Structure (Record) | |
138 | btUnion -- Union (variant) | |
139 | btEnum -- Enumerated | |
140 | btTypedef -- defined via a typedef isymRef | |
141 | btRange -- subrange of int | |
142 | btSet -- pascal sets | |
143 | btComplex -- fortran complex | |
144 | btDComplex -- fortran double complex | |
145 | btIndirect -- forward or unnamed typedef | |
146 | btFixedDec -- Fixed Decimal | |
147 | btFloatDec -- Float Decimal | |
148 | btString -- Varying Length Character String | |
149 | btBit -- Aligned Bit String | |
150 | btPicture -- Picture | |
151 | btVoid -- Void (MIPS cc revision >= 2.00) | |
152 | ||
153 | d) tq0 - tq5: type qualifier fields as needed. The | |
154 | current type qualifier fields I have documentation for | |
155 | are: | |
156 | ||
157 | tqNil -- no more qualifiers | |
158 | tqPtr -- pointer | |
159 | tqProc -- procedure | |
160 | tqArray -- array | |
161 | tqFar -- 8086 far pointers | |
162 | tqVol -- volatile | |
163 | ||
164 | ||
165 | The dense number table is used in the front ends, and disappears by | |
166 | the time the .o is created. | |
167 | ||
168 | With the 1.31 compiler suite, the optimization symbols don't seem | |
169 | to be used as far as I can tell. | |
170 | ||
171 | The linker is the first entity that creates the relative file | |
172 | descriptor table, and I believe it is used so that the individual | |
173 | file table pointers don't have to be rewritten when the objects are | |
174 | merged together into the program file. | |
175 | ||
176 | Unlike COFF, the basic symbol & string tables are split into | |
177 | external and local symbols/strings. The relocation information | |
178 | only goes off of the external symbol table, and the debug | |
179 | information only goes off of the internal symbol table. The | |
180 | external symbols can have links to an appropriate file index and | |
181 | symbol within the file to give it the appropriate type information. | |
182 | Because of this, the external symbols are actually larger than the | |
183 | internal symbols (to contain the link information), and contain the | |
184 | local symbol structure as a member, though this member is not the | |
185 | first member of the external symbol structure (!). I suspect this | |
186 | split is to make strip easier to deal with. | |
187 | ||
188 | Each file table has offsets for where the line numbers, local | |
189 | strings, local symbols, and procedure table starts from within the | |
190 | global tables, and the indexs are reset to 0 for each of those | |
191 | tables for the file. | |
192 | ||
193 | The procedure table contains the binary equivalents of the .ent | |
194 | (start of the function address), .frame (what register is the | |
195 | virtual frame pointer, constant offset from the register to obtain | |
196 | the VFP, and what register holds the return address), .mask/.fmask | |
197 | (bitmask of saved registers, and where the first register is stored | |
198 | relative to the VFP) assembler directives. It also contains the | |
199 | low and high bounds of the line numbers if debugging is turned on. | |
200 | ||
201 | The line number table is a compressed form of the normal COFF line | |
202 | table. Each line number entry is either 1 or 3 bytes long, and | |
203 | contains a signed delta from the previous line, and an unsigned | |
204 | count of the number of instructions this statement takes. | |
205 | ||
206 | The local symbol table contains the following fields: | |
207 | ||
208 | 1) iss: index to the local string table giving the name of the | |
209 | symbol. | |
210 | ||
211 | 2) value: value of the symbol (address, register number, etc.). | |
212 | ||
213 | 3) st: symbol type. The current symbol types are: | |
214 | ||
215 | stNil -- Nuthin' special | |
216 | stGlobal -- external symbol | |
217 | stStatic -- static | |
218 | stParam -- procedure argument | |
219 | stLocal -- local variable | |
220 | stLabel -- label | |
221 | stProc -- External Procedure | |
222 | stBlock -- beginning of block | |
223 | stEnd -- end (of anything) | |
224 | stMember -- member (of anything) | |
225 | stTypedef -- type definition | |
226 | stFile -- file name | |
227 | stRegReloc -- register relocation | |
228 | stForward -- forwarding address | |
229 | stStaticProc -- Static procedure | |
230 | stConstant -- const | |
231 | ||
232 | 4) sc: storage class. The current storage classes are: | |
233 | ||
234 | scText -- text symbol | |
235 | scData -- initialized data symbol | |
236 | scBss -- un-initialized data symbol | |
237 | scRegister -- value of symbol is register number | |
238 | scAbs -- value of symbol is absolute | |
239 | scUndefined -- who knows? | |
240 | scCdbLocal -- variable's value is IN se->va.?? | |
241 | scBits -- this is a bit field | |
242 | scCdbSystem -- value is IN debugger's address space | |
243 | scRegImage -- register value saved on stack | |
244 | scInfo -- symbol contains debugger information | |
245 | scUserStruct -- addr in struct user for current process | |
246 | scSData -- load time only small data | |
247 | scSBss -- load time only small common | |
248 | scRData -- load time only read only data | |
249 | scVar -- Var parameter (fortranpascal) | |
250 | scCommon -- common variable | |
251 | scSCommon -- small common | |
252 | scVarRegister -- Var parameter in a register | |
253 | scVariant -- Variant record | |
254 | scSUndefined -- small undefined(external) data | |
255 | scInit -- .init section symbol | |
256 | ||
257 | 5) index: pointer to a local symbol or aux. entry. | |
258 | ||
259 | ||
260 | ||
261 | For the following program: | |
262 | ||
263 | #include <stdio.h> | |
264 | ||
265 | main(){ | |
266 | printf("Hello World!\n"); | |
267 | return 0; | |
268 | } | |
