Hardware based profiling (e.g. hwpmc) is much better and produces more useful results. Today the profiling lib archives (_p.a) serve no real purpose other than increasing the library build time. Both upstream and base system (in commitb762974cf4) Clang have been modified to remove the special case for linking against these libraries. Clang's -pg support and mcount() remain, so building with -pg can still be used on code that the user builds; we just no longer provide prebuilt libraries compiled with -pg. Discussed on freebsd-hackers[1] / freebsd-current [2] in 2020 and freebsd-arch [3] in 2021. A deprecation notice was added in commit175841285e.

# Option file for src builds.
|
|
#
|
|
# Users define WITH_FOO and WITHOUT_FOO on the command line or in /etc/src.conf
|
|
# and /etc/make.conf files. These translate in the build system to MK_FOO={yes,no}
|
|
# with (usually) sensible defaults.
|
|
#
|
|
# Makefiles must include bsd.opts.mk after defining specific MK_FOO options that
|
|
# are applicable for that Makefile (typically there are none, but sometimes there
|
|
# are exceptions). Recursive makes usually add MK_FOO=no for options that they wish
|
|
# to omit from that make.
|
|
#
|
|
# Makefiles must include bsd.mkopt.mk before they test the value of any MK_FOO
|
|
# variable.
|
|
#
|
|
# Makefiles may also assume that this file is included by bsd.own.mk should it
|
|
# need variables defined there prior to the end of the Makefile where
|
|
# bsd.{subdir,lib.bin}.mk is traditionally included.
|
|
#
|
|
# The old-style YES_FOO and NO_FOO are being phased out. No new instances of them
|
|
# should be added. Old instances should be removed since they were just to
|
|
# bridge the gap between FreeBSD 4 and FreeBSD 5.
|
|
#
|
|
# Makefiles should never test WITH_FOO or WITHOUT_FOO directly (although an
|
|
# exception is made for _WITHOUT_SRCONF which turns off this mechanism
|
|
# completely).

|
# These should be tested with `== "no"' or `!= "no"' in makefiles.
