[repeat revision 1.85]
Fix "make tags" to actually build a tags file:
- Use !commands() instead of !target(), so that the rule actually works
- Write to ${.OBJDIR}/tags for read-only source (don't know why ${.TARGET}
isn't sufficient).
- Only match *.[cly] from ${.ALLSRCS} - just excluding *.h causes failures
because of ${targ}: subdir-${targ} in bsd.subdir.mk.
Thanks to uwe@ for assistance.
Revert my recent 1.85 revision that fixed "make tags". It causes too
much build breakage elsewhere in the tree that needs to be resolved first.
Issues include:
- Directories using TESTS_CXX with .cpp and .cxx extension instead of the
default .cc extension (see bsd.prog.mk). Most of these have been fixed.
- external/gpl3/gcc build of .cc files. (No idea what's wrong there).

add some missing ${COPTS.${.IMPSRC:T}} and ${CPUFLAGS.${.IMPSRC:T}}
to the dependancy rules.
this makes it possible to have C++ files .d files created with the
C++ compiler, and with the normal options for this file, which
means that we can build libstdc++-v3 from gcc 4.8.
Honour this for dependency processing in bsd.dep.mk. Switch i386 and
amd64 assembly to use ISO C90 preprocessor concat and drop the
-traditional-cpp on this platform.
:M-[IDU]*
with
:C/-([IDU])[ ]*/-\1/Wg:M-[IDU]*
so that arguments with whitespace after them work correctly.
Resolves [toolchain/18248] from Andrew White at Motorola.
Be consisent in this syntax; previously we'd sometimes we'd just have :M-[ID]*
which would ignore -Ufoo ...
(This needs :C///W support in make(1) that Simon Gerraty added for me :)
* Don't bother prefixing commands with a line of ${_MKCMD}\
and instead rely upon "make -s". This is less intrusive on
all the Makefiles than the former. Idea from David Laight.
* Rename the variables use to print messages. The scheme now is:
_MKMSG_FOO Run _MKMSG 'foo'
_MKTARGET_FOO Run _MKMSG_FOO ${.TARGET}
From discussion with Alistair Crooks.
${_MKMSG} " ... {$.TARGET}" and use appropriately.
Provide _MKMSGLINK.m to provide "link" message by itself (without ${.TARGET})
Replace _MKSHCMD with _MKSHECHO
Supported values:
0 Minimal output ("quiet")
1 Describe what is occurring
2 Describe what is occurring and echo the actual command ("verbose")
This is the default, and is equivalent to the previous behaviour.
* DPSRCS contains extra dependencies, but is _NOT_ added to CLEANFILES.
This is a change of behaviour. If a Makefile wants the clean semantics
it must specifically append to CLEANFILES.
Resolves PR toolchain/5204.
* To recap: .d (depend) files are generated for all files in SRCS and DPSRCS
that have a suffix of: .c .m .s .S .C .cc .cpp .cxx
* If YHEADER is set, automatically add the .y->.h to DPSRCS & CLEANFILES
* Ensure that ${OBJS} ${POBJS} ${LOBJS} ${SOBJS} *.d depend upon ${DPSRCS}
* Deprecate the (short lived) DEPENDSRCS
Update the various Makefiles to these new semantics; generally either
adding to CLEANFILES (because DPSRCS doesn't do that anymore), or replacing
specific .o dependencies with DPSRCS entries.
Tested with "make -j 8 distribution" and "make distribution".
"make: out of memory" problem when make dependencies in lib/libc.
XXX: this is a temporary workaround. i'm working on cleaning up how
the DPSRCS stuff is used throughout the tree...
some build problems where DPSRCS contains .h files that need to exist to
build the .d file.
document that bsd.dep.mk should be included after anything that might
update SRCS or DPSRCS so that the above works correctly, and actually
ensure this is the case.
This also fixes a problem in the previous where the .ALLSRC would contain
any other dependencies that .depend had, thus breaking the mkdep invocation.
Provide DEPENDSRCS which effectively contains ".depend *.dep", to be
used in other Makefiles that want to add dependencies for .depend.
(that was formerly only used for HOST_CYGWIN.).
Clean up implementation to minimise unnecessary variable munging.
Ensure all .dep files are deleted in cleandepend:.
This allows us to correctly support CPPFLAGS.<file> in make depend, and
whilst this method is marginally slower in the "no existing .depend file"
case, it should be faster in the "rebuilding depend for a subset of
source files" case.
includes. for GCC3, set this to -I instead of -isystem.
XXX this should really be either not required or a -isystem-cxx, but for
now this is required to build libstdc++-v3, which otherwise complains
heavily about STL headers not being C code(!)
