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