 160 # If the inferior stops at the first instruction of a source line, GDB
 161 # won't print the actual PC value; the source line is enough to
 162 # exactly specify the PC.  But if the inferior is instead stopped in
 163 # the midst of a source line, GDB will include the PC in the
 164 # breakpoint hit message.  This way, GDB always provides the exact
 165 # stop location, but avoids clutter when possible.
 166 #
 167 # Suppose you have a function written completely on one source line, like:
 168 #    int foo (int x) { return 0; }
 169 # Setting a breakpoint at `foo' actually places the breakpoint after
 170 # foo's prologue.
 171 #
 172 # GCC's STABS writer always emits a line entry attributing the
 173 # prologue instructions to the line containing the function's open
 174 # brace, even if the first user instruction is also on that line.
 175 # This means that, in the case of a one-line function, you will get
 176 # two line entries in the debug info for the same line: one at the
 177 # function's entry point, and another at the first user instruction.
 178 # GDB preserves these duplicated line entries, and prefers the later
 179 # one; thus, when the program stops after the prologue, at the first
 180 # user instruction, GDB's search finds the second line entry, decides
 181 # that the PC is indeed at the beginning of a source line, and doesn't
 182 # print an address in the breakpoint hit message.
 183 #
 184 # GCC's Dwarf2 writer, on the other hand, squeezes out duplicate line
 185 # entries, so GDB considers the source line to begin at the start of
 186 # the function's prologue.  Thus, if the program stops at the
 187 # breakpoint, GDB will decide that the PC is not at the beginning of a
 188 # source line, and will print an address.
 189 #
 190 # I think the Dwarf2 writer's behavior is arguably correct, but not
 191 # helpful.  If the user sets a breakpoint at that source line, they
 192 # want that breakpoint to fall after the prologue.  Identifying the
 193 # prologue's code with the opening brace is nice, but it shouldn't
 194 # take precedence over real code.
 195 #
 196 # Until the Dwarf2 writer gets fixed, I'm going to XFAIL its behavior.
