| # If the inferior stops at the first instruction of a source line, GDB |
| # won't print the actual PC value; the source line is enough to |
| # exactly specify the PC. But if the inferior is instead stopped in |
| # the midst of a source line, GDB will include the PC in the |
| # breakpoint hit message. This way, GDB always provides the exact |
| # stop location, but avoids clutter when possible. |
| # |
| # Suppose you have a function written completely on one source line, like: |
| # int foo (int x) { return 0; } |
| # Setting a breakpoint at `foo' actually places the breakpoint after |
| # foo's prologue. |
| # |
| # GCC's STABS writer always emits a line entry attributing the |
| # prologue instructions to the line containing the function's open |
| # brace, even if the first user instruction is also on that line. |
| # This means that, in the case of a one-line function, you will get |
| # two line entries in the debug info for the same line: one at the |
| # function's entry point, and another at the first user instruction. |
| # GDB preserves these duplicated line entries, and prefers the later |
| # one; thus, when the program stops after the prologue, at the first |
| # user instruction, GDB's search finds the second line entry, decides |
| # that the PC is indeed at the beginning of a source line, and doesn't |
| # print an address in the breakpoint hit message. |
| # |
| # GCC's Dwarf2 writer, on the other hand, squeezes out duplicate line |
| # entries, so GDB considers the source line to begin at the start of |
| # the function's prologue. Thus, if the program stops at the |
| # breakpoint, GDB will decide that the PC is not at the beginning of a |
| # source line, and will print an address. |
| # |
| # I think the Dwarf2 writer's behavior is arguably correct, but not |
| # helpful. If the user sets a breakpoint at that source line, they |
| # want that breakpoint to fall after the prologue. Identifying the |
| # prologue's code with the opening brace is nice, but it shouldn't |
| # take precedence over real code. |
| # |
| # Until the Dwarf2 writer gets fixed, I'm going to XFAIL its behavior. |
