Two reasons:
|
|
|
|
|
|
1999-07-07 22:19:36 +02:00
|
|
|
|
1) xlc (IBM's native c compiler) postpones static function code
|
|
|
|
|
emission to the end of a compilation unit. This way it can
|
|
|
|
|
determine if those functions (statics) are needed or not, and
|
|
|
|
|
can do some garbage collection (I think). This makes line
|
|
|
|
|
numbers and corresponding addresses unordered, and we end up
|
|
|
|
|
with a line table like:
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
lineno addr
|
|
|
|
|
foo() 10 0x100
|
|
|
|
|
20 0x200
|
|
|
|
|
30 0x300
|
|
|
|
|
|
|
|
|
|
foo3() 70 0x400
|
|
|
|
|
80 0x500
|
|
|
|
|
90 0x600
|
|
|
|
|
|
|
|
|
|
static foo2()
|
|
|
|
|
40 0x700
|
|
|
|
|
50 0x800
|
|
|
|
|
60 0x900
|
|
|
|
|
|
|
|
|
|
and that breaks gdb's binary search on line numbers, if the
|
|
|
|
|
above table is not sorted on line numbers. And that sort
|
|
|
|
|
should be on function based, since gcc can emit line numbers
|
|
|
|
|
like:
|
|
|
|
|
|
|
|
|
|
10 0x100 - for the init/test part of a for stmt.
|
|
|
|
|
20 0x200
|
|
|
|
|
30 0x300
|
|
|
|
|
10 0x400 - for the increment part of a for stmt.
|
|
|
|
|
|
|
|
|
|
arrange_linetable() will do this sorting.
|
|
|
|
|
|
|
|
|
|
2) aix symbol table might look like:
|
|
|
|
|
|
|
|
|
|
c_file // beginning of a new file
|
|
|
|
|
.bi // beginning of include file
|
|
|
|
|
.ei // end of include file
|
|
|
|
|
.bi
|
|
|
|
|
.ei
|
|
|
|
|
|
|
|
|
|
basically, .bi/.ei pairs do not necessarily encapsulate
|
|
|
|
|
their scope. They need to be recorded, and processed later
|
|
|
|
|
on when we come the end of the compilation unit.
|
|
|
|
|
Include table (inclTable) and process_linenos() handle
|
|
|
|
|
that. */
