| 126 | # If the inferior stops at the first instruction of a source line, GDB |
| 127 | # won't print the actual PC value; the source line is enough to |
| 128 | # exactly specify the PC. But if the inferior is instead stopped in |
| 129 | # the midst of a source line, GDB will include the PC in the |
| 130 | # breakpoint hit message. This way, GDB always provides the exact |
| 131 | # stop location, but avoids clutter when possible. |
| 132 | # |
| 133 | # Suppose you have a function written completely on one source line, like: |
| 134 | # int foo (int x) { return 0; } |
| 135 | # Setting a breakpoint at `foo' actually places the breakpoint after |
| 136 | # foo's prologue. |
| 137 | # |
| 138 | # GCC's STABS writer always emits a line entry attributing the |
| 139 | # prologue instructions to the line containing the function's open |
| 140 | # brace, even if the first user instruction is also on that line. |
| 141 | # This means that, in the case of a one-line function, you will get |
| 142 | # two line entries in the debug info for the same line: one at the |
| 143 | # function's entry point, and another at the first user instruction. |
| 144 | # GDB preserves these duplicated line entries, and prefers the later |
| 145 | # one; thus, when the program stops after the prologue, at the first |
| 146 | # user instruction, GDB's search finds the second line entry, decides |
| 147 | # that the PC is indeed at the beginning of a source line, and doesn't |
| 148 | # print an address in the breakpoint hit message. |
| 149 | # |
| 150 | # GCC's Dwarf2 writer, on the other hand, squeezes out duplicate line |
| 151 | # entries, so GDB considers the source line to begin at the start of |
| 152 | # the function's prologue. Thus, if the program stops at the |
| 153 | # breakpoint, GDB will decide that the PC is not at the beginning of a |
| 154 | # source line, and will print an address. |
| 155 | # |
| 156 | # I think the Dwarf2 writer's behavior is arguably correct, but not |
| 157 | # helpful. If the user sets a breakpoint at that source line, they |
| 158 | # want that breakpoint to fall after the prologue. Identifying the |
| 159 | # prologue's code with the opening brace is nice, but it shouldn't |
| 160 | # take precedence over real code. |
| 161 | # |
| 162 | # Until the Dwarf2 writer gets fixed, I'm going to XFAIL its behavior. |
