12:59 <lindi-> probe process("/usr/sbin/openvpn").function("buf_write") { foo($src, $size); } fails with cannot take address of object in register: identifier '$src' at :27:16 function: buf_valid at ./src/openvpn/buffer.h:219 inlined by buf_safe at ./src/openvpn/buffer.h:516 inlined by buf_write_alloc at ./src/openvpn/buffer.h:632 inlined by buf_write at ./src/openvpn/buffer.h:664 inlined by buf_write_u8 at ./src/openvpn/buffer.h:689 inlined by status_read at .

12:59 <lindi-> is my best bet just to recompile so that the particular function is marked with __attribute__((noinline)) or someting?

13:27 <drsmith> lindi-: that is certainly worth a try

13:31 <lindi-> drsmith: seems to work

13:31 <drsmith> good deal

14:30 <fche> lindi-, [man error::dwarf] includes a few other suggestions too

15:02 <lindi-> fche: would it be possible to make a probe that'd just print contents of all registers so that you could manually choose which value actually is the one you want in such an inlined location?

15:03 <fche> print_regs()

15:03 <lindi-> I already feel silly for not checking that out :)

15:03 <lindi-> thanks!

15:03 <fche> man -k function::print

15:03 <fche> man -k function::regist

15:07 <fche> (there's no guarantee that the value is in any register)
