.stabd, .stabn, .stabs
There are three directives that begin
All emit symbols (see Symbols), for use by symbolic debuggers.
The symbols are not entered in the
as hash table: they
cannot be referenced elsewhere in the source file.
Up to five fields are required:
\000, so is more general than ordinary symbol names. Some debuggers used to code arbitrarily complex structures into symbol names using this field.
ldand debuggers choke on silly bit patterns.
If a warning is detected while reading a
.stabs statement, the symbol has probably already been created;
you get a half-formed symbol in your object file. This is
compatible with earlier assemblers!
.stabd type , other , desc
The symbol's value is set to the location counter,
relocatably. When your program is linked, the value of this symbol
is the address of the location counter when the
