--- Comment #1 from agentzh <agentzh at gmail dot com> ---
We'll take a stab at implementing `process.statement(0xaddr)` first for
inode-based uprobes, with relative addresses in the executable files (including
DSO and PIE). This will pave a way to true DWARF-less probing (with the
existing @vma() facility which will get merge soon) as well as implementing our
own uretprobes without all the consequences from the kernel's uretprobes.
Messed up C stacks are really problematic for stack unwinding and resizable
stacks.
