Yep, try ktrace. You'll need the KTRACE option in your kernel:
options KTRACE
Compile and install the kernel, then reboot.
Then, run ktrace on an executable
ktrace ls
You'll get a ktrace.out file you can read with kdump.
kdump ktrace.out
See ktrace(1) and kdump(1) for plenty of more information.

Two babies were born on the same day at the same hospital. They lay
there and looked at each other. Their families came and took them
away. Eighty years later, by a bizarre coincidence, they lay in the
same hospital, on their deathbeds, next to each other. One of them
looked at the other and said, "So. What did you think?"
