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