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.
Clarify that command-line overrides of the MKxxx variables should be
done via the environment rather than make(1) command-line variable
assignment, since the latter doesn't actually work as intended.
only list the (often complicated) ${COMPILE.*} rules once always building
to ${.TARGET}.tmp. Then, depending on whether *OPTS has -g, either
"mv ${.TARGET}.tmp ${.TARGET}" or "${LD} -[xX] -r ${TARGET}.tmp -o ${.TARGET}"
as appropriate.
This can prevent inconsistency that could occur between "echo ${COMPILE.*:Q}"
and "${COMPILE.*}", such as the problem in rev 1.226. (There were still
examples of this in .cc.so and .m.so !!!)
Remove `@' from most non-echo rules, so that we can actually see what's
happening. This helps debugging problems, such as that fixed by rev 1.226.
Always remove all possible temp files that might occur because of the above.
Be consistent about ${CC} instead of $(CC)
includes. for GCC3, set this to -I instead of -isystem.
XXX this should really be either not required or a -isystem-cxx, but for
now this is required to build libstdc++-v3, which otherwise complains
heavily about STL headers not being C code(!)
to determine TARGET_ENDIANNESS.
This should fix problem reported privately by Matt Green <mrg@>.
This uses exists(${CC:ts::C/:.*$//}) as we don't expect the command name to
contain `:'. (The ":ts" trick is from a discussion with Simon Gerraty <sjg@>.)

a non-zero exit value to indicate a missing file or non-symlink),
instead of test -h $l && ltarg=`ls -ld $l | awk '{print $NF}'`
since the former is quicker and more concise.
and target (and rely upon a non-zero exit value to indicate a missing file),
instead instead of unconditionally installing the link.
SYMLINKS: use stat -qf '%Y' $l to read a symlink's target (and rely upon
a non-zero exit value to indicate a missing file or non-symlink),
instead of test -h $l && ls -ld $l | awk '{print $NF}' , since
the former is quicker and more concise.
This resolves PR toolchain/16885 from David Laight.
Replace defined(UNPRIVED) tests with ${MKUNPRIVED} != "no"
Add MKUPDATE; if not no has the same semantics as if UPDATE was defined.
Replace defined(UPDATE) tests with ${MKUPDATE} != "no"
Improve documentation for these and other make flags.
This replaces the previous .if defined (MANZ) behaviour, although the latter
will set MKMANZ=yes for compatibility purposes.
Don't bother with -P-bou in TOOL_ROFF_HTML; it doesn't appear to be
necessary with groff 1.19.
Fix NOHTML implementation to be consistent with other NOxxx / MKxxx
variables, and expose the user-tweakable MKHTML.

to
top-of-obj/tooldir.OS-VERSION-STRING
It's more consistent with the build.sh defaults for DESTDIR and
RELEASEDIR, and it's easier on "mr lazy completion fingers".
