Enhance the information collected by the function recorder to include
the call site and entry/exit counts. This allows fnrec.pl to produce
a call tree such as:
step (from core/getkey.c:46 = 0x17e90) {
ref_increment (from core/process.c:93 = 0x73ec) { }
net_step (from core/process.c:96 = 0x73f1) {
net_poll (from net/netdevice.c:741 = 0xbce6) {
netdev_poll (from net/netdevice.c:700 = 0xbc58) { }
netdev_rx_dequeue (from net/netdevice.c:709 = 0xbc65) { }
}
}
ref_decrement (from core/process.c:96 = 0x73f9) { }
}
Note that inlined functions are reported, confusingly, as extra calls
to the *containing* function. Minimise this confusion by adding the
attribute "no_instrument_function" to all functions declared as
inline. (Static functions that have been inlined autonomously by gcc
will still be problematic, but these are far fewer in number.)
