20 /* mike@tredysvr.Tredydev.Unisys.COM says:
21 I modified the struct.c example and have a nm of a .o resulting from the
22 AT&T C compiler. From the example below I would conclude the following:
24 1. All .defs from structures are emitted as scanned. The example below
25 clearly shows the symbol table entries for BoxRec2 are after the first
28 2. All functions and their locals (including statics) are emitted as scanned.
30 3. All nested unnamed union and structure .defs must be emitted before
31 the structure in which they are nested. The AT&T assembler is a
32 one pass beast as far as symbolics are concerned.
34 4. All structure .defs are emitted before the typedefs that refer to them.
36 5. All top level static and external variable definitions are moved to the
37 end of file with all top level statics occurring first before externs.
39 6. All undefined references are at the end of the file.
