- Subject: missing entrypc dwarf line record
Hi-
In testing in s390x I found the following tap script is producing this
error.
jpr.stp:
probe kernel.function("jprobe_return") {}
stap -p4 -vv jpr.stp
Pass 1: parsed user script and 47 library script(s) in
990usr/30sys/1042real ms.
semantic error: missing entrypc dwarf line record for function
'jprobe_return'
semantic error: no match for probe point
while: resolving probe point kernel.function("jprobe_return")
jprobe_return is black-listed but it is not helping..
void __kprobes jprobe_return(void)
{
asm volatile (".word 0x0002");
}
Any hints on how to fix this one?
