/* The following function's implementation starts by including a file
|
||
|
|
(break-include.inc) which contains a copyright header followed by
|
||
|
|
a single C statement. When we place a breakpoint on the line where
|
||
|
|
the function name is declared, we expect GDB to skip the function's
|
||
|
|
prologue, and insert the breakpoint on the first line of "user" code
|
||
|
|
for that function, which we have set up to be that single statement
|
||
|
|
break-include.inc provides.
|
||
|
|
|
||
|
|
The purpose of this testcase is to verify that, when we insert
|
||
|
|
that breakpoint, GDB reports the location as being in that include
|
||
|
|
file, but also using the correct line number inside that include
|
||
|
|
file -- NOT the line number we originally used to insert the
|
||
|
|
breakpoint, nor the location where the file is included from.
|
||
|
|
In order to verify that GDB shows the right line number, we must
|
||
|
|
be careful that this first statement located in break-include.inc
|
||
|
|
and our function are not on the same line number. Otherwise,
|
||
|
|
we could potentially have a false PASS.
|
||
|
|
|
||
|
|
This is why we implement the following function as far away
|
||
|
|
from the start of this file as possible, as we know that
|
||
|
|
break-include.inc is a fairly short file (copyright header
|
||
|
|
and single statement only). */
