29 | /* The following function's implementation starts by including a file | |
30 | (break-include.inc) which contains a copyright header followed by | |
31 | a single C statement. When we place a breakpoint on the line where | |
32 | the function name is declared, we expect GDB to skip the function's | |
33 | prologue, and insert the breakpoint on the first line of "user" code | |
34 | for that function, which we have set up to be that single statement | |
35 | break-include.inc provides. | |
36 | ||
37 | The purpose of this testcase is to verify that, when we insert | |
38 | that breakpoint, GDB reports the location as being in that include | |
39 | file, but also using the correct line number inside that include | |
40 | file -- NOT the line number we originally used to insert the | |
41 | breakpoint, nor the location where the file is included from. | |
42 | In order to verify that GDB shows the right line number, we must | |
43 | be careful that this first statement located in break-include.inc | |
44 | and our function are not on the same line number. Otherwise, | |
45 | we could potentially have a false PASS. | |
46 | ||
47 | This is why we implement the following function as far away | |
48 | from the start of this file as possible, as we know that | |
49 | break-include.inc is a fairly short file (copyright header | |
50 | and single statement only). */ | |
