<lindi-> is there some way to access the first argument of a user space function when you don't have debug symbols? I can use u_register("rdi") on amd64 but that is obviously not portable
<wcohen> lindi-, you might take a look at how the no dwarf (nd_syscalls) syscalls are done, using int_arg, long_arg, etc. on https://sourceware.org/systemtap/tapsets/
<lindi-> wcohen: ah, so those are valid for user space probes as well?
<wcohen> lindi-, that is a good question. I thought that the userspace probes also have ptreg struct, so they should be.
<lindi-> wcohen: _stp_arg2 has this "regs = (CONTEXT->user_mode_p ? CONTEXT->uregs : CONTEXT->kregs)"
