21 | # Modified to test gdb's handling of separate debug info files. | |
22 | ||
23 | # This file has two parts. The first is testing that gdb behaves | |
24 | # normally after reading in an executable and its corresponding | |
25 | # separate debug file. The second moves the .debug file to a different | |
26 | # location and tests the "set debug-file-directory" command. | |

885 | # (one before the prologue and one after) with the same line number, | |
886 | # but dwarf regards these as duplicates and discards one of them. | |

888 | # has no exactly matching line symbol, and GDB reports the breakpoint | |
889 | # as if it were in the middle of a line rather than at the beginning. | |
