-/* Here is a brief description of the MIPS ECOFF symbol table. The
- MIPS symbol table has the following pieces:
-
- Symbolic Header
- |
- +-- Auxiliary Symbols
- |
- +-- Dense number table
- |
- +-- Optimizer Symbols
- |
- +-- External Strings
- |
- +-- External Symbols
- |
- +-- Relative file descriptors
- |
- +-- File table
- |
- +-- Procedure table
- |
- +-- Line number table
- |
- +-- Local Strings
- |
- +-- Local Symbols
-
- The symbolic header points to each of the other tables, and also
- contains the number of entries. It also contains a magic number
- and MIPS compiler version number, such as 2.0.
-
- The auxiliary table is a series of 32 bit integers, that are
- referenced as needed from the local symbol table. Unlike standard
- COFF, the aux. information does not follow the symbol that uses
- it, but rather is a separate table. In theory, this would allow
- the MIPS compilers to collapse duplicate aux. entries, but I've not
- noticed this happening with the 1.31 compiler suite. The different
- types of aux. entries are:
-
- 1) dnLow: Low bound on array dimension.
-
- 2) dnHigh: High bound on array dimension.
-
- 3) isym: Index to the local symbol which is the start of the
- function for the end of function first aux. entry.
-
- 4) width: Width of structures and bitfields.
-
- 5) count: Count of ranges for variant part.
-
- 6) rndx: A relative index into the symbol table. The relative
- index field has two parts: rfd which is a pointer into the
- relative file index table or ST_RFDESCAPE which says the next
- aux. entry is the file number, and index: which is the pointer
- into the local symbol within a given file table. This is for
- things like references to types defined in another file.
-
- 7) Type information: This is like the COFF type bits, except it
- is 32 bits instead of 16; they still have room to add new
- basic types; and they can handle more than 6 levels of array,
- pointer, function, etc. Each type information field contains
- the following structure members:
-
- a) fBitfield: a bit that says this is a bitfield, and the
- size in bits follows as the next aux. entry.
-
- b) continued: a bit that says the next aux. entry is a
- continuation of the current type information (in case
- there are more than 6 levels of array/ptr/function).
-
- c) bt: an integer containing the base type before adding
- array, pointer, function, etc. qualifiers. The
- current base types that I have documentation for are:
-
- btNil -- undefined
- btAdr -- address - integer same size as ptr
- btChar -- character
- btUChar -- unsigned character
- btShort -- short
- btUShort -- unsigned short
- btInt -- int
- btUInt -- unsigned int
- btLong -- long
- btULong -- unsigned long
- btFloat -- float (real)
- btDouble -- Double (real)
- btStruct -- Structure (Record)
- btUnion -- Union (variant)
- btEnum -- Enumerated
- btTypedef -- defined via a typedef isymRef
- btRange -- subrange of int
- btSet -- pascal sets
- btComplex -- fortran complex
- btDComplex -- fortran double complex
- btIndirect -- forward or unnamed typedef
- btFixedDec -- Fixed Decimal
- btFloatDec -- Float Decimal
- btString -- Varying Length Character String
- btBit -- Aligned Bit String
- btPicture -- Picture
- btVoid -- Void (MIPS cc revision >= 2.00)
-
- d) tq0 - tq5: type qualifier fields as needed. The
- current type qualifier fields I have documentation for
- are:
-
- tqNil -- no more qualifiers
- tqPtr -- pointer
- tqProc -- procedure
- tqArray -- array
- tqFar -- 8086 far pointers
- tqVol -- volatile
-
-
- The dense number table is used in the front ends, and disappears by
- the time the .o is created.
-
- With the 1.31 compiler suite, the optimization symbols don't seem
- to be used as far as I can tell.
-
- The linker is the first entity that creates the relative file
- descriptor table, and I believe it is used so that the individual
- file table pointers don't have to be rewritten when the objects are
- merged together into the program file.
-
- Unlike COFF, the basic symbol & string tables are split into
- external and local symbols/strings. The relocation information
- only goes off of the external symbol table, and the debug
- information only goes off of the internal symbol table. The
- external symbols can have links to an appropriate file index and
- symbol within the file to give it the appropriate type information.
- Because of this, the external symbols are actually larger than the
- internal symbols (to contain the link information), and contain the
- local symbol structure as a member, though this member is not the
- first member of the external symbol structure (!). I suspect this
- split is to make strip easier to deal with.
-
- Each file table has offsets for where the line numbers, local
- strings, local symbols, and procedure table starts from within the
- global tables, and the indexs are reset to 0 for each of those
- tables for the file.
-
- The procedure table contains the binary equivalents of the .ent
- (start of the function address), .frame (what register is the
- virtual frame pointer, constant offset from the register to obtain
- the VFP, and what register holds the return address), .mask/.fmask
- (bitmask of saved registers, and where the first register is stored
- relative to the VFP) assembler directives. It also contains the
- low and high bounds of the line numbers if debugging is turned on.
-
- The line number table is a compressed form of the normal COFF line
- table. Each line number entry is either 1 or 3 bytes long, and
- contains a signed delta from the previous line, and an unsigned
- count of the number of instructions this statement takes.
-
- The local symbol table contains the following fields:
-
- 1) iss: index to the local string table giving the name of the
- symbol.
-
- 2) value: value of the symbol (address, register number, etc.).
-
- 3) st: symbol type. The current symbol types are:
-
- stNil -- Nuthin' special
- stGlobal -- external symbol
- stStatic -- static
- stParam -- procedure argument
- stLocal -- local variable
- stLabel -- label
- stProc -- External Procedure
- stBlock -- beginning of block
- stEnd -- end (of anything)
- stMember -- member (of anything)
- stTypedef -- type definition
- stFile -- file name
- stRegReloc -- register relocation
- stForward -- forwarding address
- stStaticProc -- Static procedure
- stConstant -- const
-
- 4) sc: storage class. The current storage classes are:
-
- scText -- text symbol
- scData -- initialized data symbol
- scBss -- un-initialized data symbol
- scRegister -- value of symbol is register number
- scAbs -- value of symbol is absolute
- scUndefined -- who knows?
- scCdbLocal -- variable's value is IN se->va.??
- scBits -- this is a bit field
- scCdbSystem -- value is IN debugger's address space
- scRegImage -- register value saved on stack
- scInfo -- symbol contains debugger information
- scUserStruct -- addr in struct user for current process
- scSData -- load time only small data
- scSBss -- load time only small common
- scRData -- load time only read only data
- scVar -- Var parameter (fortranpascal)
- scCommon -- common variable
- scSCommon -- small common
- scVarRegister -- Var parameter in a register
- scVariant -- Variant record
- scSUndefined -- small undefined(external) data
- scInit -- .init section symbol
-
- 5) index: pointer to a local symbol or aux. entry.
