gprof(1) gprof(1)

Parents that are not proﬁled have the time of their proﬁled children propagated to them, but they appear to

be spontaneously invoked in the call graph listing, and do not have their time propagated further. Simi-

larly, signal catchers, even though proﬁled, appear to be spontaneous (although for more obscure reasons).

Any proﬁled children of signal catchers should have their times propagated properly unless the signal

catcher was invoked during the execution of the proﬁling routine, in which case all is lost.

The following limitations exist for gprof shared library proﬁling on PA-RISC systems:

• Local, static, and hidden functions are not proﬁled.

• Shared libraries built with -B symbolic

are not proﬁled.

• Any function calls made from library initializers are not collected.

DEPENDENCIES

gprof cannot be used with dynamically linked executables (built with

ld -A in pre-HP-UX 10.20

releases).

AUTHOR

gprof was developed by the University of California, Berkeley.
