bt(5), btrace(8): execute END probe and print non-empty maps upon exit() BPFTrace's exit() statement executes the END probe (if any) and prints the contents of all non-empty maps before terminating the interpreter. Implement this in btrace(8) with a halting check after each statement. If a statement causes the program to halt, the condition bubbles up to the top-level evaluation loop and causes rules_teardown() to run immediately. btrace(8) still performs a full rules_setup() if exit() is called during the BEGIN probe, though the top-level evaluation loop is never run. One edge-like case: an exit() from the END probe is treated as an early return; END is not executed multiple times. Thread: https://marc.info/?l=openbsd-tech&m=169765169420751&w=2 ok mpi@

bt(5)/btrace(8): add support for str() Implement initial support for the str() function, which is used primarily to truncate or NUL-terminate strings from either cli args or args to tracepoints and syscalls. Current implementation only supports cli args and is primarily for compatability with bpftrace. Future work is needed once dt(4) supports builtin args other than long values. Adds a regress test and wires in argument-based tests again. ok mpi@

Implement linear and power-of-two histograms: hist() and lhist() keywords.
This is built on top of maps which are currently built on top of RB-trees.
Improvements are welcome! For example the use of a hashing table as pointed
by espie@.
The following one-liner produce an histogram of power-of-two values returned
by the read(2) syscall:
btrace 'syscall:read:return { @bytes = hist(retval); }'
^C
