41 /* The ECOFF file format uses COFF style sections, but with a unique
42 debugging format. We just build generic BFD sections since BFD
43 knows how to write them out. The debugging format, however, we
44 must construct here; all BFD knows at the moment is to write it out
45 as a large block of data.
47 We support both COFF style debugging and stabs debugging (the stabs
48 symbols are encapsulated in COFF symbols). This should let us
49 handle anything the compiler might throw at us. Parsing the COFF
50 and stabs debugging information is similar to work done by COFF and
51 a.out targets, but since the result is completely different the
52 code is not shared. */
54 /* Here is a brief description of the MIPS ECOFF symbol table, by
55 Michael Meissner. The MIPS symbol table has the following pieces:
61 +-- Dense number table
69 +-- Relative file descriptors
81 The symbolic header points to each of the other tables, and also
82 contains the number of entries. It also contains a magic number
83 and MIPS compiler version number, such as 2.0.
85 The auxiliary table is a series of 32 bit integers, that are
86 referenced as needed from the local symbol table. Unlike standard
87 COFF, the aux. information does not follow the symbol that uses
88 it, but rather is a separate table. In theory, this would allow
89 the MIPS compilers to collapse duplicate aux. entries, but I've not
90 noticed this happening with the 1.31 compiler suite. The different
91 types of aux. entries are:
93 1) dnLow: Low bound on array dimension.
95 2) dnHigh: High bound on array dimension.
97 3) isym: Index to the local symbol which is the start of the
98 function for the end of function first aux. entry.
100 4) width: Width of structures and bitfields.
102 5) count: Count of ranges for variant part.
104 6) rndx: A relative index into the symbol table. The relative
105 index field has two parts: rfd which is a pointer into the
106 relative file index table or ST_RFDESCAPE which says the next
107 aux. entry is the file number, and index: which is the pointer
108 into the local symbol within a given file table. This is for
109 things like references to types defined in another file.
111 7) Type information: This is like the COFF type bits, except it
112 is 32 bits instead of 16; they still have room to add new
113 basic types; and they can handle more than 6 levels of array,
114 pointer, function, etc. Each type information field contains
115 the following structure members:
117 a) fBitfield: a bit that says this is a bitfield, and the
118 size in bits follows as the next aux. entry.
120 b) continued: a bit that says the next aux. entry is a
121 continuation of the current type information (in case
122 there are more than 6 levels of array/ptr/function).
124 c) bt: an integer containing the base type before adding
125 array, pointer, function, etc. qualifiers. The
126 current base types that I have documentation for are:
129 btAdr -- address - integer same size as ptr
131 btUChar -- unsigned character
133 btUShort -- unsigned short
135 btUInt -- unsigned int
137 btULong -- unsigned long
138 btFloat -- float (real)
139 btDouble -- Double (real)
140 btStruct -- Structure (Record)
141 btUnion -- Union (variant)
143 btTypedef -- defined via a typedef isymRef
144 btRange -- subrange of int
146 btComplex -- fortran complex
147 btDComplex -- fortran double complex
148 btIndirect -- forward or unnamed typedef
149 btFixedDec -- Fixed Decimal
150 btFloatDec -- Float Decimal
151 btString -- Varying Length Character String
152 btBit -- Aligned Bit String
154 btVoid -- Void (MIPS cc revision >= 2.00)
156 d) tq0 - tq5: type qualifier fields as needed. The
157 current type qualifier fields I have documentation for
160 tqNil -- no more qualifiers
164 tqFar -- 8086 far pointers
168 The dense number table is used in the front ends, and disappears by
169 the time the .o is created.
171 With the 1.31 compiler suite, the optimization symbols don't seem
172 to be used as far as I can tell.
174 The linker is the first entity that creates the relative file
175 descriptor table, and I believe it is used so that the individual
176 file table pointers don't have to be rewritten when the objects are
177 merged together into the program file.
179 Unlike COFF, the basic symbol & string tables are split into
180 external and local symbols/strings. The relocation information
181 only goes off of the external symbol table, and the debug
182 information only goes off of the internal symbol table. The
183 external symbols can have links to an appropriate file index and
184 symbol within the file to give it the appropriate type information.
185 Because of this, the external symbols are actually larger than the
186 internal symbols (to contain the link information), and contain the
187 local symbol structure as a member, though this member is not the
188 first member of the external symbol structure (!). I suspect this
189 split is to make strip easier to deal with.
191 Each file table has offsets for where the line numbers, local
192 strings, local symbols, and procedure table starts from within the
193 global tables, and the indexs are reset to 0 for each of those
196 The procedure table contains the binary equivalents of the .ent
197 (start of the function address), .frame (what register is the
198 virtual frame pointer, constant offset from the register to obtain
199 the VFP, and what register holds the return address), .mask/.fmask
200 (bitmask of saved registers, and where the first register is stored
201 relative to the VFP) assembler directives. It also contains the
202 low and high bounds of the line numbers if debugging is turned on.
204 The line number table is a compressed form of the normal COFF line
205 table. Each line number entry is either 1 or 3 bytes long, and
206 contains a signed delta from the previous line, and an unsigned
207 count of the number of instructions this statement takes.
209 The local symbol table contains the following fields:
211 1) iss: index to the local string table giving the name of the
214 2) value: value of the symbol (address, register number, etc.).
216 3) st: symbol type. The current symbol types are:
218 stNil -- Nuthin' special
219 stGlobal -- external symbol
221 stParam -- procedure argument
222 stLocal -- local variable
224 stProc -- External Procedure
225 stBlock -- beginning of block
226 stEnd -- end (of anything)
227 stMember -- member (of anything)
228 stTypedef -- type definition
230 stRegReloc -- register relocation
231 stForward -- forwarding address
232 stStaticProc -- Static procedure
235 4) sc: storage class. The current storage classes are:
237 scText -- text symbol
238 scData -- initialized data symbol
239 scBss -- un-initialized data symbol
240 scRegister -- value of symbol is register number
241 scAbs -- value of symbol is absolute
242 scUndefined -- who knows?
243 scCdbLocal -- variable's value is IN se->va.??
244 scBits -- this is a bit field
245 scCdbSystem -- value is IN debugger's address space
246 scRegImage -- register value saved on stack
247 scInfo -- symbol contains debugger information
248 scUserStruct -- addr in struct user for current process
249 scSData -- load time only small data
250 scSBss -- load time only small common
251 scRData -- load time only read only data
252 scVar -- Var parameter (fortranpascal)
253 scCommon -- common variable
254 scSCommon -- small common
255 scVarRegister -- Var parameter in a register
256 scVariant -- Variant record
257 scSUndefined -- small undefined(external) data
258 scInit -- .init section symbol
260 5) index: pointer to a local symbol or aux. entry.
