/**
* -break-insert [ -t ] [ -h ] [ -f ] [ -d ] [ -a ]
* [ -c CONDITION ] [ -i IGNORE-COUNT ]
* [ -p THREAD ] [ LOCATION ]
*
* If specified, LOCATION, can be one of:
* * function
* * filename:linenum
* * filename:function
* * *address
*
* The possible optional parameters of this command are:
*
* '-t'
* Insert a temporary breakpoint.
*
* '-h'
* Insert a hardware breakpoint.
* When inserting a tracepoint (-a), this option indicates a fast tracepoint
*
* '-c CONDITION'
* Make the breakpoint conditional on CONDITION.
*
* '-i IGNORE-COUNT'
* Initialize the IGNORE-COUNT (number of breakpoint hits before breaking).
*
* '-f'
* If location cannot be parsed (for example if it refers to unknown files or
* functions), create a pending breakpoint. Without this flag, if a location
* cannot be parsed, the breakpoint will not be created and an error will be
* reported.
* Only available starting GDB 6.8
*
* '-d'
* Create a disabled breakpoint.
* Only available starting GDB 7.0
*
* '-a'
* Insert a tracepoint instead of a breakpoint
* Only available starting GDB 7.2
*
* '-p THREAD'
* THREAD on which to apply the breakpoint
