Add Makefile.depend.options

2019-12-19T04:58:11+00:00

Leaf directories that have dependencies impacted
by options need a Makefile.depend.options file
to avoid churn in Makefile.depend

DIRDEPS for cases such as OPENSSL, TCP_WRAPPERS etc
can be set in local.dirdeps-options.mk
which can add to those set in Makefile.depend.options

See share/mk/dirdeps-options.mk

Also update affected Makefile.depend files.

MFC r351408-r351410: reduce pollution from mips machine/regnum.h

2019-09-03T20:19:43+00:00

r351408:
libsa: mips: use _JB_* from machine/asm.h, remove regnum dep

This brings the libsa/mips _setjmp implementation closer to parity with the
libc version.

r351409:
mips: hide regnum definitions behind _KERNEL/_WANT_MIPS_REGNUM

machine/regnum.h ends up being included by sys/procfs.h and sys/ptrace.h via
machine/reg.h. Many of the regnum definitions are too short and too generic
to be exposing to any userland application including one of these two
headers. Moreover, these actively cause build failures in googletest
(template  expanding to template ).

Hide the definitions behind _KERNEL or _WANT_MIPS_REGNUM, and patch all of
the userland consumers to define as needed.

r351410:
libsa: mips: fix typo that had slipped into the diff on local machine

Implement pt_fpreg_to_ucontext(), pt_ucontext_to_fpreg().

lib: further adoption of SPDX licensing ID tags.

2017-11-26T02:00:33+00:00

Mainly focus on files that use BSD 2-Clause license, however the tool I
was using mis-identified many licenses so this was mostly a manual - error
prone - task.

The Software Package Data Exchange (SPDX) group provides a specification
to make it easier for automated tools to detect and summarize well known
opensource licenses. We are gradually adopting the specification, noting
that the tags are considered only advisory and do not, in any way,
superceed or replace the license texts.

Special thanks to Wind River for providing access to "The Duke of
Highlander" tool: an older (2014) run over FreeBSD tree was useful as a
starting point.

libpthread_db: undo the memset size change.

2017-04-20T17:58:27+00:00

I inadvertedly soubled the size of the memset without noticing the
start address had changed. The size for the memset in pt_map_thread()
shouldn't actually match the reallocarray() so undo that part of r317200.

This is a re-commit of r317201 to clarify the log.
