[GDBserver] Don't error in reinsert_raw_breakpoint if bp->inserted
GDBserver steps over a breakpoint while the single step breakpoint is inserted at the same address, there are two breakpoint objects using single raw breakpoint, which is inserted (for single step). When step over is finished, GDBserver reinsert the breakpoint, but it finds the raw breakpoint is already inserted, and error out "Breakpoint already inserted at reinsert time." Even if I change the order to delete reinsert breakpoints first (which only decreases the refcount, but leave inserted flag unchanged), the error is still there. The fix is to remove the error and return instead. gdb/gdbserver: 2016-04-25 Yao Qi <yao.qi@linaro.org> * linux-low.c (reinsert_raw_breakpoint): If bp->inserted is true return instead of error.
