Function Documentation

void gdb_stepHist_clean ( void )

clean all entries of the step history

Parameters:

-

Returns:: -

References stepHistoryContainer::first, stepHistoryContainer::last, stepHistoryElement::next, and stepHistoryContainer::num.

Referenced by gdb_action_continue(), gdb_main_loop(), gdb_monitor_Rcmd(), and gdb_restart().

void gdb_stepHist_add ( struct reg_set * new_regs )

add a new register set entry into step history

Parameters:

new_regs

add this register set of current CPU state to history

Returns:: -

References stepHistoryContainer::first, stepHistoryElement::histCPU, stepHistoryContainer::last, stepHistoryElement::next, stepHistoryContainer::num, stepHistoryElement::prev, reg_set::Regs::r, reg_set::regs, and stepHistoryContainer::size.

Referenced by gdb_main_loop().

int gdb_stepHist_loopDetect ( void )

Walk the stepping history to detect if we are inside of a loop and there is nothing that happens inside of this loop. e.g. while(1); while(bussy) {for(i=0;i<X;i++);} So it might be better signalize GDB to stop STEPPING.

Parameters:

-
