# 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.
