934# Add a second pass pattern. The behavior differs here between stabs
935# and dwarf for one-line functions. Stabs preserves two line symbols
936# (one before the prologue and one after) with the same line number,
937# but dwarf regards these as duplicates and discards one of them.
938# Therefore the address after the prologue (where the breakpoint is)
939# has no exactly matching line symbol, and GDB reports the breakpoint
940# as if it were in the middle of a line rather than at the beginning.
