Hi!

What I use for profiling various GNOME modules is:

   -ggdb -O0 -fno-omit-frame-pointer

I'm not sure how long it's been since you used Sysprof, but many years
ago (when 32-bit x86 was prevalent), Sysprof used a custom kernel
modules to get data. A while back it was changed to use the Linux perf
kernel module. There are some differences in implementation.
