/* Here is a brief description of the MIPS ECOFF symbol table. The
|
| 28 |
|
|
MIPS symbol table has the following pieces:
|
| 29 |
|
|
|
| 30 |
|
|
Symbolic Header

|

|
|
|
| 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.
|
| 57 |
|
|
|
| 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:
|
| 65 |
|
|
|
| 66 |
|
|
1) dnLow: Low bound on array dimension.
|
| 67 |
|
|
|
| 68 |
|
|
2) dnHigh: High bound on array dimension.
|
| 69 |
|
|
|
| 70 |
|
|
3) isym: Index to the local symbol which is the start of the
|
| 71 |
|
|
function for the end of function first aux. entry.
|
| 72 |
|
|
|
| 73 |
|
|
4) width: Width of structures and bitfields.
|
| 74 |
|
|
|
| 75 |
|
|
5) count: Count of ranges for variant part.
|
| 76 |
|
|
|
| 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.
|
| 83 |
|
|
|
| 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:
|
| 89 |
|
|
|
| 90 |
|
|
a) fBitfield: a bit that says this is a bitfield, and the
|
| 91 |
|
|
size in bits follows as the next aux. entry.
|
| 92 |
|
|
|
| 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).
|
| 96 |
|
|
|
| 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:
|
| 100 |
|
|
|
| 101 |
|
|
btNil -- undefined
|
| 102 |
|
|
btAdr -- address - integer same size as ptr

| 104 |
|
|
btUChar -- unsigned character
|
| 105 |
|
|
btShort -- short

|
|
btTypedef -- defined via a typedef isymRef
|
| 117 |
|
|
btRange -- subrange of int
|
| 118 |
|
|
btSet -- pascal sets
|
| 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
|
| 126 |
|
|
btPicture -- Picture
|
| 127 |
|
|
btVoid -- Void (MIPS cc revision >= 2.00)
|
| 128 |
|
|
|
| 129 |
|
|
d) tq0 - tq5: type qualifier fields as needed. The
|
| 130 |
|
|
current type qualifier fields I have documentation for
|
| 131 |
|
|
are:
|
| 132 |
|
|
|
| 133 |
|
|
tqNil -- no more qualifiers
|
| 134 |
|
|
tqPtr -- pointer
|
| 135 |
|
|
tqProc -- procedure
|
| 136 |
|
|
tqArray -- array
|
| 137 |
|
|
tqFar -- 8086 far pointers
|
| 138 |
|
|
tqVol -- volatile
|
| 139 |
|
|
|
| 140 |
|
|
|
| 141 |
|
|
The dense number table is used in the front ends, and disappears by
|
| 142 |
|
|
the time the .o is created.
|
| 143 |
|
|
|
| 144 |
|
|
With the 1.31 compiler suite, the optimization symbols don't seem
|
| 145 |
|
|
to be used as far as I can tell.
|
| 146 |
|
|
|
| 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.
|
| 151 |
|
|
|
| 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.
|
| 163 |
|
|
|
| 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
|
| 167 |
|
|
tables for the file.
|
| 168 |
|
|
|
| 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.
|
| 176 |
|
|
|
| 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.
|
| 181 |
|
|
|
| 182 |
|
|
The local symbol table contains the following fields:
|
| 183 |
|
|
|
| 184 |
|
|
1) iss: index to the local string table giving the name of the
|
| 185 |

|
2) value: value of the symbol (address, register number, etc.).
