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