144 | # If the inferior stops at the first instruction of a source line, GDB |
145 | # won't print the actual PC value; the source line is enough to | |
146 | # exactly specify the PC. But if the inferior is instead stopped in | |
147 | # the midst of a source line, GDB will include the PC in the | |
148 | # breakpoint hit message. This way, GDB always provides the exact | |
149 | # stop location, but avoids clutter when possible. | |
150 | # | |
151 | # Suppose you have a function written completely on one source line, like: | |
2c415c0f | 152 | # int foo (int x) { return 0; } |
11cf8741 JM |
153 | # Setting a breakpoint at `foo' actually places the breakpoint after |
154 | # foo's prologue. | |
155 | # | |
156 | # GCC's STABS writer always emits a line entry attributing the | |
157 | # prologue instructions to the line containing the function's open | |
158 | # brace, even if the first user instruction is also on that line. | |
159 | # This means that, in the case of a one-line function, you will get | |
160 | # two line entries in the debug info for the same line: one at the | |
161 | # function's entry point, and another at the first user instruction. | |
162 | # GDB preserves these duplicated line entries, and prefers the later | |
163 | # one; thus, when the program stops after the prologue, at the first | |
164 | # user instruction, GDB's search finds the second line entry, decides | |
165 | # that the PC is indeed at the beginning of a source line, and doesn't | |
166 | # print an address in the breakpoint hit message. | |
167 | # | |
168 | # GCC's Dwarf2 writer, on the other hand, squeezes out duplicate line | |
169 | # entries, so GDB considers the source line to begin at the start of | |
170 | # the function's prologue. Thus, if the program stops at the | |
171 | # breakpoint, GDB will decide that the PC is not at the beginning of a | |
172 | # source line, and will print an address. | |
173 | # | |
174 | # I think the Dwarf2 writer's behavior is arguably correct, but not | |
175 | # helpful. If the user sets a breakpoint at that source line, they | |
176 | # want that breakpoint to fall after the prologue. Identifying the | |
177 | # prologue's code with the opening brace is nice, but it shouldn't | |
178 | # take precedence over real code. | |
179 | # | |
180 | # Until the Dwarf2 writer gets fixed, I'm going to XFAIL its behavior. | |
