@end defmac
@defmac DBX_OUTPUT_STANDARD_TYPES (@var{syms})
Define this macro if you need to control the order of output of the
standard data types at the beginning of compilation. The argument
@var{syms} is a @code{tree} which is a chain of all the predefined
global symbols, including names of data types.
Normally, DBX output starts with definitions of the types for integers
and characters, followed by all the other predefined types of the
particular language in no particular order.
On some machines, it is necessary to output different particular types
first. To do this, define @code{DBX_OUTPUT_STANDARD_TYPES} to output
those symbols in the necessary order. Any predefined types that you
don't explicitly output will be output afterward in no particular order.
Be careful not to define this macro so that it works only for C@. There
are no global variables to access most of the built-in types, because
another language may have another set of types. The way to output a
particular type is to look through @var{syms} to see if you can find it.
Here is an example:
@smallexample
@{
tree decl;
for (decl = syms; decl; decl = TREE_CHAIN (decl))
if (!strcmp (IDENTIFIER_POINTER (DECL_NAME (decl)),
"long int"))
dbxout_symbol (decl);
@dots{}
@}
@end smallexample
@noindent
This does nothing if the expected type does not exist.
See the function @code{init_decl_processing} in @file{c-decl.c} to find
the names to use for all the built-in C types.
Here is another way of finding a particular type:
@c this is still overfull. --mew 10feb93
@smallexample
@{
tree decl;
for (decl = syms; decl; decl = TREE_CHAIN (decl))
if (TREE_CODE (decl) == TYPE_DECL
&& (TREE_CODE (TREE_TYPE (decl))
== INTEGER_CST)
&& TYPE_PRECISION (TREE_TYPE (decl)) == 16
&& TYPE_UNSIGNED (TREE_TYPE (decl)))
@group
/* @r{This must be @code{unsigned short}.} */
dbxout_symbol (decl);
@dots{}
@}
@end group
@end smallexample
@end defmac
@defmac NO_DBX_FUNCTION_END
Some stabs encapsulation formats (in particular ECOFF), cannot handle the
@code{.stabs "",N_FUN,,0,0,Lscope-function-1} gdb dbx extension construct.
