lttv -m textDump -t /tmp/trace1 -e "event.facility=user_generic & (event.name=function_entry & event.name=function_exit)"
It will show, for example :
-user_generic.function_entry: 59329.709939111 (/cpu_0), 19250, 18581, SYSCALL {
-0x8048454, 0x80484c2 }
-user_generic.function_exit: 59329.709944613 (/cpu_0), 19250, 18581, SYSCALL { 0
-x8048454, 0x80484c2 }
+user_generic.function_entry: 59329.709939111 (/cpu_0), 19250, 18581, SYSCALL { 0x8048454, 0x80484c2 }
+user_generic.function_exit: 59329.709944613 (/cpu_0), 19250, 18581, SYSCALL { 0x8048454, 0x80484c2 }
you can then use (from the binutils package)
addr2line -e sample-instrument-fct -i -f 0x8048454
