static int plain_type_1 ( )

static

Return the .type value for type TYPE.

   LEVEL indicates how many levels deep we have recursed into the type.
   The SDB debug format can only represent 6 derived levels of types.
   After that, we must output inaccurate debug info.  We deliberately
   stop before the 7th level, so that ADA recursive types will not give an
   infinite loop.

static void sdbout_begin_block	(	unsigned	int,
		unsigned	int
	)

static

static void sdbout_begin_block ( )

static

Describe the beginning of an internal block within a function.
   Also output descriptions of variables defined in this block.

   N is the number of the block, by order of beginning, counting from 1,
   and not counting the outermost (function top-level) block.
   The blocks match the BLOCKs in DECL_INITIAL (current_function_decl),
   if the count starts at 0 for the outermost one.

static void sdbout_begin_prologue	(	unsigned	int,
		const char *

static

static void sdbout_begin_prologue ( )

static

Called at beginning of function body after prologue.  Record the

static void sdbout_field_types ( )

static

Output types of the fields of type TYPE, if they are structs.

   They must come before TYPE, since forward refs are not allowed.
   Now james@bigtex.cactus.org says to try them.

static void sdbout_one_type ( )

static

Use this to put out the top level defined record and union types
   for later reference.  If this is a struct with a name, then put that
   name out.  Other unnamed structs will have .xxfake labels generated so
   that they may be referred to later.
   The label will be stored in the KNOWN_TYPE_TAG slot of a type.
   It may NOT be called recursively.

static void sdbout_parms ( tree )

static

Referenced by sdbout_end_prologue().

static void sdbout_parms ( )

static

The following two functions output definitions of function parameters.
   Each parameter gets a definition locating it in the parameter list.
   Each parameter that is a register variable gets a second definition
   locating it in the register.

   Printing or argument lists in gdb uses the definitions that
   locate in the parameter list.  But reference to the variable in
   expressions uses preferentially the definition as a register.

Output definitions, referring to storage in the parmlist,
   of all the parms in PARMS, which is a chain of PARM_DECL nodes.

static void sdbout_reg_parms ( tree )

static

Referenced by sdbout_end_prologue().

static void sdbout_reg_parms ( )

static

Output definitions for the places where parms live during the function,
   when different from where they were passed, when the parms were passed
   in memory.

   It is not useful to do this for parms passed in registers
   that live during the function in different registers, because it is
   impossible to look in the passed register for the passed value,
   so we use the within-the-function register to begin with.

   PARMS is a chain of PARM_DECL nodes.

   number LINE.

mike@tredysvr.Tredydev.Unisys.COM says:
I modified the struct.c example and have a nm of a .o resulting from the
AT&T C compiler.  From the example below I would conclude the following:

1. All .defs from structures are emitted as scanned.  The example below
   clearly shows the symbol table entries for BoxRec2 are after the first
   function.

2. All functions and their locals (including statics) are emitted as scanned.

3. All nested unnamed union and structure .defs must be emitted before
   the structure in which they are nested.  The AT&T assembler is a
   one pass beast as far as symbolics are concerned.

4. All structure .defs are emitted before the typedefs that refer to them.

5. All top level static and external variable definitions are moved to the
   end of file with all top level statics occurring first before externs.

6. All undefined references are at the end of the file.
