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