When wildcard probing function returns, invariably one hits a problem: [ananth@... ~]$ stap -ve 'probe kernel.function("*@fs/exec.c").return { printf("%s\n", $return) }' Pass 1: parsed user script and 51 library script(s) in 520usr/40sys/925real ms. semantic error: function free_bprm(fs/exec.c) has no return value: identifier '$return' at <input>:1:62 source: probe kernel.function("*@fs/exec.c").return { printf("%s\n", $return) } ^ Pass 2: analyzed script: 29 probe(s), 19 function(s), 0 embed(s), 0 global(s) in 370usr/760sys/1399real ms. Pass 2: analysis failed. Try again with another '--vp 01' option. Would it be possible to emit a warning or a string "no $return in this context" instead of aborting as above?
