/* Here is a brief description of the MIPS ECOFF symbol table, by
|
54 |
|
|
Michael Meissner. The MIPS symbol table has the following pieces:
|
55 |
|
|
|
56 |
|
|
Symbolic Header
|
57 |
|
|
|
|
58 |
|
|
+-- Auxiliary Symbols
|
59 |
|
|
|
|
60 |
|
|
+-- Dense number table
|
61 |
|
|
|
|
62 |
|
|
+-- Optimizer Symbols
|
63 |
|
|
|
|
64 |
|
|
+-- External Strings
|
65 |
|
|
|
|
66 |
|
|
+-- External Symbols
|
67 |
|
|
|
|
68 |
|
|
+-- Relative file descriptors
|
69 |
|
|
|
|
70 |
|
|
+-- File table
|
71 |
|
|
|
|
72 |
|
|
+-- Procedure table
|
73 |
|
|
|
|
74 |
|
|
+-- Line number table
|
75 |
|
|
|
|
76 |
|
|
+-- Local Strings
|
77 |
|
|
|
|
78 |
|
|
+-- Local Symbols
|
79 |
|
|
|
80 |
|
|
The symbolic header points to each of the other tables, and also
|
81 |
|
|
contains the number of entries. It also contains a magic number
|
82 |
|
|
and MIPS compiler version number, such as 2.0.
|
83 |
|
|
|
84 |
|
|
The auxiliary table is a series of 32 bit integers, that are
|
85 |
|
|
referenced as needed from the local symbol table. Unlike standard
|
86 |
|
|
COFF, the aux. information does not follow the symbol that uses
|
87 |
|
|
it, but rather is a separate table. In theory, this would allow
|
88 |
|
|
the MIPS compilers to collapse duplicate aux. entries, but I've not
|
89 |
|
|
noticed this happening with the 1.31 compiler suite. The different
|
90 |
|
|
types of aux. entries are:
|
91 |
|
|
|
92 |
|
|
1) dnLow: Low bound on array dimension.
|
93 |
|
|
|
94 |
|
|
2) dnHigh: High bound on array dimension.
|
95 |
|
|
|
96 |
|
|
3) isym: Index to the local symbol which is the start of the
|
97 |
|
|
function for the end of function first aux. entry.
|
98 |
|
|
|
99 |
|
|
4) width: Width of structures and bitfields.
|
100 |
|
|
|
101 |
|
|
5) count: Count of ranges for variant part.
|
102 |
|
|
|
103 |
|
|
6) rndx: A relative index into the symbol table. The relative
|
104 |
|
|
index field has two parts: rfd which is a pointer into the
|
105 |
|
|
relative file index table or ST_RFDESCAPE which says the next
|
106 |
|
|
aux. entry is the file number, and index: which is the pointer
|
107 |
|
|
into the local symbol within a given file table. This is for
|
108 |
|
|
things like references to types defined in another file.
|
109 |
|
|
|
110 |
|
|
7) Type information: This is like the COFF type bits, except it
|
111 |
|
|
is 32 bits instead of 16; they still have room to add new
|
112 |
|
|
basic types; and they can handle more than 6 levels of array,
|
113 |
|
|
pointer, function, etc. Each type information field contains
|
114 |
|
|
the following structure members:
|
115 |
|
|
|
116 |
|
|
a) fBitfield: a bit that says this is a bitfield, and the
|
117 |
|
|
size in bits follows as the next aux. entry.
|
118 |
|
|
|
119 |
|
|
b) continued: a bit that says the next aux. entry is a
|
120 |
|
|
continuation of the current type information (in case
|
121 |
|
|
there are more than 6 levels of array/ptr/function).
|
122 |
|
|
|
123 |
|
|
c) bt: an integer containing the base type before adding
|
124 |
|
|
array, pointer, function, etc. qualifiers. The
|
125 |
|
|
current base types that I have documentation for are:
|
126 |
|
|
|
127 |
|
|
btNil -- undefined
|
128 |
|
|
btAdr -- address - integer same size as ptr
|
129 |
|
|
btChar -- character
|
130 |
|
|
btUChar -- unsigned character
|
131 |
|
|
btShort -- short
|
132 |
|
|
btUShort -- unsigned short
|
133 |
|
|
btInt -- int
|
134 |
|
|
btUInt -- unsigned int
|
135 |
|
|
btLong -- long
|
136 |
|
|
btULong -- unsigned long
|
137 |
|
|
btFloat -- float (real)
|
138 |
|
|
btDouble -- Double (real)
|
139 |
|
|
btStruct -- Structure (Record)
|
140 |
|
|
btUnion -- Union (variant)
|
141 |
|
|
btEnum -- Enumerated
|
142 |
|
|
btTypedef -- defined via a typedef isymRef
|
143 |
|
|
btRange -- subrange of int
|
144 |
|
|
btSet -- pascal sets
|
145 |
|
|
btComplex -- fortran complex
|
146 |
|
|
btDComplex -- fortran double complex
|
147 |
|
|
btIndirect -- forward or unnamed typedef
|
148 |
|
|
btFixedDec -- Fixed Decimal
|
149 |
|
|
btFloatDec -- Float Decimal
|
150 |
|
|
btString -- Varying Length Character String
|
151 |
|
|
btBit -- Aligned Bit String
|
152 |
|
|
btPicture -- Picture
|
153 |
|
|
btVoid -- Void (MIPS cc revision >= 2.00)
|
154 |
|
|
|
155 |
|
|
d) tq0 - tq5: type qualifier fields as needed. The
|
156 |
|
|
current type qualifier fields I have documentation for
|
157 |
|
|
are:
|
158 |
|
|
|
159 |
|
|
tqNil -- no more qualifiers
|
160 |
|
|
tqPtr -- pointer
|
161 |
|
|
tqProc -- procedure
|
162 |
|
|
tqArray -- array
|
163 |
|
|
tqFar -- 8086 far pointers
|
164 |
|
|
tqVol -- volatile
|
165 |
|
|
|
166 |
|
|
The dense number table is used in the front ends, and disappears by
|
167 |
|
|
the time the .o is created.
|
168 |
|
|
|
169 |
|
|
With the 1.31 compiler suite, the optimization symbols don't seem
|
170 |
|
|
to be used as far as I can tell.
|
171 |
|
|
|
172 |
|
|
The linker is the first entity that creates the relative file
|
173 |
|
|
descriptor table, and I believe it is used so that the individual
|
174 |
|
|
file table pointers don't have to be rewritten when the objects are
|
175 |
|
|
merged together into the program file.
|
176 |
|
|
|
177 |
|
|
Unlike COFF, the basic symbol & string tables are split into
|
178 |
|
|
external and local symbols/strings. The relocation information
|
179 |
|
|
only goes off of the external symbol table, and the debug
|
180 |
|
|
information only goes off of the internal symbol table. The
|
181 |
|
|
external symbols can have links to an appropriate file index and
|
182 |
|
|
symbol within the file to give it the appropriate type information.
|
183 |
|
|
Because of this, the external symbols are actually larger than the
|
184 |
|
|
internal symbols (to contain the link information), and contain the
|
185 |
|
|
local symbol structure as a member, though this member is not the
|
186 |
|
|
first member of the external symbol structure (!). I suspect this
|
187 |
|
|
split is to make strip easier to deal with.
|
188 |
|
|
|
189 |
|
|
Each file table has offsets for where the line numbers, local
|
190 |
|
|
strings, local symbols, and procedure table starts from within the
|
191 |
|
|
global tables, and the indexs are reset to 0 for each of those
|
192 |
|
|
tables for the file.
|
193 |
|
|
|
194 |
|
|
The procedure table contains the binary equivalents of the .ent
|
195 |
|
|
(start of the function address), .frame (what register is the
|
196 |
|
|
virtual frame pointer, constant offset from the register to obtain
|
197 |
|
|
the VFP, and what register holds the return address), .mask/.fmask
|
198 |
|
|
(bitmask of saved registers, and where the first register is stored
|
199 |
|
|
relative to the VFP) assembler directives. It also contains the
|
200 |
|
|
low and high bounds of the line numbers if debugging is turned on.
|
201 |
|
|
|
202 |
|
|
The line number table is a compressed form of the normal COFF line
|
203 |
|
|
table. Each line number entry is either 1 or 3 bytes long, and
|
204 |
|
|
contains a signed delta from the previous line, and an unsigned
|
205 |
|
|
count of the number of instructions this statement takes.
|
206 |
|
|
|
207 |
|
|
The local symbol table contains the following fields:
|
208 |
|
|
|
209 |
|
|
1) iss: index to the local string table giving the name of the
|
210 |

213 |
