09:14 <sona> hi, is there any way to suppress MAXSTRINGLEN macro?

10:47 <sona> fche, oky

10:48 <sona> drsmith_away, yep , oky

11:01 <sona> i am trying to understand the o/p of some backtraces. It's like this : afr_lookup_cbk+0x30d [afr.so]. So here 0x30d is what?? line number ??

12:13 <fche> 0x30d is an offset against the .so base address

12:14 <fche> to get more detailed backtraces, run stap with -d /path/to/afr.so --ldd

12:34 <sona> fche, oky

12:36 <sona> fche, one more thing, i was trying to include all modules/libraries to get full traces using -all-modules

12:37 <fche> --all-modules is for kernel modules, not all userspace shared libraries

12:37 <fche> (the latter would be gargantuan)

12:38 <sona> so is there any way to include all userspace modules in one go?

12:38 <sona> inspite of everytime specifying each of them using -d

12:41 <sona> like to get full traces i have to specify every time -d path/to/shared-objectfiles/ (which are large in number and have different paths)

12:41 <sona> so any smart way of doing this ?

12:42 <sona> fche,

12:56 <invano__> Hello guys. I'm currently dealing with systemtap on multiple archs. I was wondering if systemtap can handle syscall args passed through the stack instead of registers. I'm having a look at various tapsets and looks like it assumes stp_args taken from registers only. Is that correct?

13:02 <fche> invano__, no

13:03 <fche> if debuginfo is available, stap will find the arguments exactly where the compiler says they are - registers, stack, whereever

13:03 <fche> if debuginfo is not available, the nd_syscall variant will make abi assumptions, but those are per-arch abis

13:03 <invano__> sorry, I forgot to say that I'm in the case where debuginfo are not available

13:04 <invano__> ah ok got it, thanks fche

13:06 <invano__> I'm working on mips now, no debuginfo, and I have an abi mismatch I think. registers.stp tries to get args from registers only even if in mips o32abi args from 4th on are on the stack.

13:07 <invano__> probably I'll patch it to make it work with mips o32 abi without debuginfo
