| // in one of them the function at m_line_number is used (and so code and a line entry for it is generated) but in the |
| // other it isn't. If we considered the CU's independently, then in the second inclusion, we'd move the breakpoint |
| // to the next function that actually generated code in the header file. That would end up being confusing. |
| // So instead, we do the CU iterations by hand here, then scan through the complete list of matches, and figure out |
| // the closest line number match, and only set breakpoints on that match. |
| |
| // Note also that if file_spec only had a file name and not a directory, there may be many different file spec's in |
| // the resultant list. The closest line match for one will not be right for some totally different file. |
| // So we go through the match list and pull out the sets that have the same file spec in their line_entry |
| // and treat each set separately. |
