-/* Output dbx-format symbol table data.
- This consists of many symbol table entries, each of them
- a .stabs assembler pseudo-op with four operands:
- a "name" which is really a description of one symbol and its type,
- a "code", which is a symbol defined in stab.h whose name starts with N_,
- an unused operand always 0,
- and a "value" which is an address or an offset.
- The name is enclosed in doublequote characters.
-
- Each function, variable, typedef, and structure tag
- has a symbol table entry to define it.
- The beginning and end of each level of name scoping within
- a function are also marked by special symbol table entries.
-
- The "name" consists of the symbol name, a colon, a kind-of-symbol letter,
- and a data type number. The data type number may be followed by
- "=" and a type definition; normally this will happen the first time
- the type number is mentioned. The type definition may refer to
- other types by number, and those type numbers may be followed
- by "=" and nested definitions.
-
- This can make the "name" quite long.
- When a name is more than 80 characters, we split the .stabs pseudo-op
- into two .stabs pseudo-ops, both sharing the same "code" and "value".
- The first one is marked as continued with a double-backslash at the
- end of its "name".
-
- The kind-of-symbol letter distinguished function names from global
- variables from file-scope variables from parameters from auto
- variables in memory from typedef names from register variables.
- See `dbxout_symbol'.
-
- The "code" is mostly redundant with the kind-of-symbol letter
- that goes in the "name", but not entirely: for symbols located
- in static storage, the "code" says which segment the address is in,
- which controls how it is relocated.
-
- The "value" for a symbol in static storage
- is the core address of the symbol (actually, the assembler
- label for the symbol). For a symbol located in a stack slot
- it is the stack offset; for one in a register, the register number.
- For a typedef symbol, it is zero.
-
- If DEBUG_SYMS_TEXT is defined, all debugging symbols must be
- output while in the text section.
-
- For more on data type definitions, see `dbxout_type'. */

-@defmac DBX_OUTPUT_MAIN_SOURCE_FILENAME (@var{stream}, @var{name})
-A C statement to output DBX debugging information to the stdio stream
-@var{stream}, which indicates that file @var{name} is the main source
-file---the file specified as the input file for compilation.
-This macro is called only once, at the beginning of compilation.
-
-This macro need not be defined if the standard form of output
-for DBX debugging information is appropriate.
-
-It may be necessary to refer to a label equal to the beginning of the
-text section. You can use @samp{assemble_name (stream, ltext_label_name)}
-to do so. If you do this, you must also set the variable
-@var{used_ltext_label_name} to @code{true}.

-of the current directory for compilation and current source language at
-the beginning of the file.
-@end defmac
-
-@defmac NO_DBX_GCC_MARKER
-Define this macro, with value 1, if GCC should not emit an indication
-that this object file was compiled by GCC@. The default is to emit
-an @code{N_OPT} stab at the beginning of every source file, with
-@samp{gcc2_compiled.} for the string and value 0.
-@end defmac
-
-@defmac DBX_OUTPUT_MAIN_SOURCE_FILE_END (@var{stream}, @var{name})
-A C statement to output DBX debugging information at the end of
-compilation of the main source file @var{name}. Output should be
-written to the stdio stream @var{stream}.
-
-If you don't define this macro, nothing special is output at the end
-of compilation, which is correct for most machines.
-@end defmac

-@defmac DBX_OUTPUT_NULL_N_SO_AT_MAIN_SOURCE_FILE_END
-Define this macro @emph{instead of} defining

-whose value is the highest absolute text address in the file.
