Some of GDB's trace test cases define a function end() and place a breakpoint there with "break end". However, when libinproctrace is linked to the binary, there are multiple methods named "end", such as std::string::end() from the C++ library or format_pieces::end() from common/format.h. GDB then creates multiple breakpoints instead of just a single one, and some FAILs result, such as these: FAIL: gdb.trace/trace-mt.exp: ftrace on: break end FAIL: gdb.trace/trace-mt.exp: ftrace off: break end Fix this by adding the "-qualified" option to the break commands. For consistency, change all occurrences of "break end" (and similar) in all trace test cases, even if the current behavior does not cause problems. Also, consequently use the gdb_breakpoint convenience proc. gdb/testsuite/ChangeLog: * gdb.trace/actions-changed.exp: Call gdb_breakpoint with the "qualified" option when setting breakpoints. * gdb.trace/backtrace.exp: Likewise. * gdb.trace/circ.exp: Likewise. * gdb.trace/collection.exp: Likewise. * gdb.trace/disconnected-tracing.exp: Likewise. * gdb.trace/ftrace-lock.exp: Likewise. * gdb.trace/ftrace.exp: Likewise. * gdb.trace/infotrace.exp: Likewise. * gdb.trace/packetlen.exp: Likewise. * gdb.trace/passc-dyn.exp: Likewise. * gdb.trace/qtro.exp: Likewise. * gdb.trace/read-memory.exp: Likewise. * gdb.trace/report.exp: Likewise. * gdb.trace/signal.exp: Likewise. * gdb.trace/status-stop.exp: Likewise. * gdb.trace/strace.exp: Likewise. * gdb.trace/tfind.exp: Likewise. * gdb.trace/trace-break.exp: Likewise. * gdb.trace/trace-condition.exp: Likewise. * gdb.trace/trace-mt.exp: Likewise. * gdb.trace/tstatus.exp: Likewise. * gdb.trace/tsv.exp: Likewise. * gdb.trace/unavailable-dwarf-piece.exp: Likewise. * gdb.trace/unavailable.exp: Likewise. * gdb.trace/while-dyn.exp: Likewise.
