|
||||
|
||||
Process the DIE's within a single compilation unit, looking for
|
||||
interesting DIE's that contribute to the partial symbol table entry
|
||||
for this compilation unit. Since we cannot follow any sibling
|
||||
chains without reading the complete DIE info for every DIE,
|
||||
it is probably faster to just sequentially check each one to
|
||||
see if it is one of the types we are interested in, and if so,
|
||||
then extract all the attributes info and generate a partial
|
||||
symbol table entry.
|
||||
for this compilation unit.
|
||||
|
||||
NOTES
|
||||
|
||||
There are some DIE's that may appear both at file scope and within
|
||||
the scope of a function. We are only interested in the ones at file
|
||||
scope, and the only way to tell them apart is to keep track of the
|
||||
scope. For example, consider the test case:
|
||||
|
||||
static int i;
|
||||
main () { int j; }
|
||||
|
||||
for which the relevant DWARF segment has the structure:
|
||||
|
||||
0x51:
|
||||
0x23 global subrtn sibling 0x9b
|
||||
name main
|
||||
fund_type FT_integer
|
||||
low_pc 0x800004cc
|
||||
high_pc 0x800004d4
|
||||
|
||||
0x74:
|
||||
0x23 local var sibling 0x97
|
||||
name j
|
||||
fund_type FT_integer
|
||||
location OP_BASEREG 0xe
|
||||
OP_CONST 0xfffffffc

||||

|
||||

|
||||
0x4
|
||||
|
||||
0x9b:
|
||||
0x1d local var sibling 0xb8
|
||||
name i
|
||||
fund_type FT_integer
|
||||
location OP_ADDR 0x800025dc
|
||||
|
||||
0xb8:
|
||||
0x4
|
||||
|
||||
We want to include the symbol 'i' in the partial symbol table, but
|
||||
not the symbol 'j'. In essence, we want to skip all the dies within
|
||||
the scope of a TAG_global_subroutine DIE.
|
||||
|
||||
Don't attempt to add anonymous structures or unions since they have
|
||||
no name. Anonymous enumerations however are processed, because we
|
||||
want to extract their member names (the check for a tag name is
