Quite extensive rewrite of the Suff module. Some ripple effects into
Parse and Targ modules too.
Dependency searches in general were made to honor explicit rules so
implicit and explicit sources are no longer applied on targets that
do not invoke a transformation rule.
Archive member dependency search was rewritten. Explicit rules now
work properly and $(.TARGET) is set correctly. POSIX semantics for
lib(member.o) and .s1.a rules are supported.
.SUFFIXES list maintenance was rewritten so that scanning of existing
rules works when suffixes are added and that clearing the suffix list
removes single suffix rules too. Transformation rule nodes are now
mixed with regular nodes so they are available as regular targets too
if needed (especially after the known suffixes are cleared).
The .NULL target was documented in the manual page, especially to
warn against using it when a single suffix rule would work.
A deprecation warning was also added to the manual and make also
warns the user if it encounters .NULL.
Search for suffix rules no longer allows the explicit dependencies
to override the selected transformation rule. A check is made in
the search that the transformation that would be tried does not
already exist in the chain. This prevents getting stuck in an infinite
loop under specific circumstances. Local variables are now set
before node's children are expanded so dynamic sources work in
multi-stage transformations. Make_HandleUse() no longer expands
the added children for transformation nodes, preventing triple
expansion and allowing the Suff module to properly postpone their
expansion until proper values are set for the local variables.
Directory prefix is no longer removed from $(.PREFIX) if the target
is found via directory search.
The last rule defined is now used instead of the first one (POSIX
requirement) in case a rule is defined multiple times. Everything
defined in the first instance is undone, but things added "globally"
are honored. To implement this, each node tracks attribute bits
which have been set by special targets (global) instead of special
sources (local). They also track dependencies that were added by
a rule with commands (local) instead of rule with no commands (global).
New attribute, OP_FROM_SYS_MK is introduced. It is set on all targets
found in system makefiles so that they are not eligible to become
the main target. We cannot just set OP_NOTMAIN because it is one of
the attributes inherited from transformation and .USE rules and would
make any eligible target that uses a built-in inference rule ineligible.
The $(.IMPSRC) local variable now works like in gmake: it is set to
the first prerequisite for explicit rules. For implicit rules it
is still the implied source.
The manual page is improved regarding the fixed features. Test cases
for the fixed problems are added.
Other improvements in the Suff module include:
- better debug messages for transformation rule search (length of
the chain is now visualized by indentation)
- Suff structures are created, destroyed and moved around by a set
of maintenance functions so their reference counts are easier
to track (this also gets rid of a lot of code duplication)
- some unreasonably long functions were split into smaller ones
- many local variables had their names changed to describe their
purpose instead of their type
Don't exit from var.c:Var_Parse() before possible modifiers are handled
on D and F modified versions of local variables. Properly expand $(?D)
and $(?F) too.
Make line continuations in rule's commands POSIX compliant.
Fix the syntax error caused by lib(member) as the last target before
a dependency operator.
Document the line continuation change in the manual page. Also talk
more about the POSIX style local variables and their modifiers.
Add tests covering the fixed problems into d_posix.mk. The test is
a known failure at the moment because of PR 49086 and PR 49092.

its tailq. This required introducing a new flag in the TAGQ structure to
avoid reverting to poking under the hood of the queue.h API.
The concrete bug it solves is that using tags would make vi crash reliably
on exit.
copies of them.
* Remove all old tests from src/tests/usr.bin/make/d_*. These tests
were unmaintained old copies of the actual tests which are maintained
under src/usr.bin/make/unit-tests. One exception is the test in
d_unmatchedvarparen.mk, which was new, but has nw been added to
src/usr.bin/make/unit-tests/varmisc.mk.
* In src/tests/usr.bin/make/Makefile, copy all
the tests from src/usr.bin/make/unit-tests to
${DESTDIR}/usr/tests/usr.bin/make/unit-tests.
* In src/tests/usr.bin/make/t_make.sh, run the tests installed above,
instead of the old tests.
* In etc/mtree/NetBSD.dist.tests, create the
usr/tests/usr.bin/make/unit-tests diectory.
* Update the set lists for all the above.
This was split up so we could map the GTT prefetchable without
interfering with the MMIO registers, but it interferes with old drm
which tries to map the whole region and which is still hooked up for
the moment.
Once we unhook old drm for good we can put this back.
was: attach route domain if found from domains link set
now: attach any domain which is found from domains link set
No functional change to monolithic kernel. In a rump kernel, which
attaches networking domains "modularly", prevents domains from
accidentally leaking in via the link set in static linked scenarios.
Problem reported by cube, Tom Bousso, and the voices in my head.
For now, the only test is copied from
src/tests/usr.bin/make/d_unmatchedvarparen.mk. This was
the only test in src/tests/usr.bin/make that was not also in
src/usr.bin/make/unit-tests.
XXX: src/tests/usr.bin/mk should be changed to reach over to
src/usr.bin/make/unit-tests, instead of keeping out of date copies
of the tests.
I've been unable to find any code that actually uses the mapping and we may
want to read the ROM from drm2.
If no users show up within a week or so I'll delete it.
* Rename each sub-makefile to *.mk;
* Add a *.exp file of expected output for each sub-makefile;
* Remove test.exp, which is replaced by all the other *.exp files.
* Use suffix rules to generate *.rawout and *.out files for
each test case.
* Rewrite the test and accept targets to adapt to the new way.
The old (now removed) test.exp file is almost identical to the
concatenation (in the correct order) of all the new *.exp files. There
are expected differences in makefile names embedded in the output, and
the new "exit status" lines. Some old "*** Error code 1 (ignored)"
lines are also removed (replaced by new "exit status 1" lines).
