libraries for space-constraint systems. The description is based on the
feedback of hubertf@, the logic on input from lukem@
This obsoletes the removal of LIBC_SCCS and SYSLIBC_SCCS for libc builds.
If not "no", install as ${LIB}.so (without the "lib" prefix),
and act as "MKDEBUGLIB=no MKLINT=no MKPICINSTALL=no
MKPROFILE=no MKSTATICLIB=no".
Default: no
so that we still link in the crt* start/end files.
Explicitly link libc against gcc_pic, since -nodefaultlibs undoes this.
Fixes problems where shared libraries don't get init/fini sections,
most easily noticable with pthreads programs not working.

Use relative symlinks for /usr/lib/libfoo.so -> /lib/libfoo.so.M.N
This should work now that "install -l r -d destdir" works if destdir
contains a symlink.
libname path-to-srcdir-of-libname
For each tuple;
* LIBDO.libname contains the .OBJDIR of the library `libname', and
if it is not set it is determined from the srcdir and added to
MAKEOVERRIDES (the latter is to allow for build time optimization).
* LDADD gets -L${LIBDO.libname} -llibname added.
* DPADD gets ${LIBDO.libname}/liblibname.so added.
library objects, rather than using OBJS to refer to them. This gives us
a separate variable to refer to static library objects that does not affect
profile library objects (which has POBJS) or shared library objects (which
has SOBJS).
and don't install the (.a) library.
This is useful for "build only" helper libraries.
* Add some #{ [...] #} comments around large conditional statements.
- support ${COPTS.<fn>} ${CPUFLAGS.<fn>} ${CPPFLAGS.<fn>}
(deficiency noted by Tyler Retzlaff <rtr@NetBSD.org>)
- use ${COMPILE.s} for .s.o .s.po .s.so (instead of ${COMPILE.S})
- don't support AINC anymore; append to AFLAGS instead
Remove .c.ln - it was a duplicate of the rule in <bsd.sys.mk>
and exception handling have a chance of working properly.
- creates libgcc, libgcc_eh and libgcc_s
- updates LIBGCC_SPEC to use them appropriately.
There's a hack in here at the moment with respect to libgcc_so in that it
is preferable to link against libgcc_so will only when -shared-libgcc is
specified (the c++ frontend does this automatically.) Configurations where
LINK_EH_SPEC is defined already do this. The gcc configuration for
NetBSD/alpha and another NetBSD platform (I forget which) actually define
LINK_EH_SPEC probably by accident rather than design.
- updates share/mk to use the compiler's knowledge of what needs linking into
libraries and executables. This removes an hppa hack.
- updates the sets for the newly created libgcc* files.
- support for linking against the _pg version of libgcc has been removed.
This simplifies using ld with ${DESTDIR}/usr/lib whilst retaining the
(slightly faster) absolute links for the run-time libraries.
Per discussion on tech-toolchain.
(Side note; install(1) -l r needs the source to be prefixed with ${DESTDIR}
to operate correctly, which makes it non trivial to enable '-l r' by default
for all ${INSTALL_SYMLINK}s)
: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
