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