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.

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

1. 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.

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

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

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

vec<tree, va_gc>* deferred_global_decls

static

Declarations whose debug info was deferred till end of compilation.

tree preinit_symbols

static

The C front end may call sdbout_symbol before sdbout_init runs. We save all such decls in this list and output them when we get to sdbout_init.

bool sdbout_initialized

static

int unnamed_struct_number

static

Counter to generate unique "names" for nameless struct members.
