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: | |
2c415c0f | 134 | # int foo (int x) { return 0; } |
11cf8741 JM |
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. | |
