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
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.
on the setting of ${SHLIBDIR} and ${SHLIBINSTALLDIR} (_not_ ${_LIBSODIR}).
Fixes cruel and unusual ^W^W^W obscure native-build and not-so-obscure
cross-builds problems I was having with shared libraries with a
non-base LIBDIR (e.g, /usr/X11R6/lib) that use LDADD to pull in other
libraries from /usr/lib (such as libm) which are really in /lib and the
symlink from ${DESTDIR}/usr/lib/libm.so to /lib/libm.so.N.M was confusing
the linker. Stuffing -rpath-link ${DESTDIR}/lib in solves the problem.
This should mean that shared libraries that depend upon other shared
libraries in other directories should DTRT in a DESTDIR (cross-)build...
Inspired by _PROGLDOPTS in <bsd.prog.mk>
* 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".
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(!)
COPTS.<fn> Additional flags to the compiler when creating the C objects

(g)cc has all the knowledge which startfiles/libgcc to

Externally visible change:
Shared objects are linked against libgcc_pic.a now
(if the in-tree gcc2 is used). This fixes problems with
dlopen()'ed objects referencing libgcc functions not used
(thus not linked in) by the main program.
things like the .note.netbsd.ident section are provided by crti/crtn.
crti/crtn also provide the _init() and _fini() routines.
crtbegin/crtend now only provide support for ctors/dtors. This paves
the way to using the "crtstuff" provided with GCC (when we upgrade to
GCC 3.3), which provides, among other things, much better C++/Java
exception handling.
and the sources now use that define, so there is no need for us to define
ABICALLS. Since that was the only use for the AINC variable, garbage-collect
it.
-dynamic-linker=/libexec/ld.elf_so) if the BINDIR of the program being
built is /bin or /sbin.
The reason we do this is because now all programs *except* those in
/bin and /sbin (i.e. the "special cases") match the default the compiler
uses, which is what is used for things in e.g. xsrc, pkgsrc, and other
random 3rd party programs.
This is done by decoupling where a shlib is installed from how it
is located. Two new variables, SHLIBINSTALLDIR and SHLINKINSTALLDIR,
contain the former information, and key off MKDYNAMICROOT only. SHLIBDIR
and SHLINKDIR contain the latter, and key off MKDYNAMICROOT and BINDIR.
The SHLIBINSTALLDIR, SHLIBDIR, _LIBSODIR, SHLINKINSTALLDIR, and
SHLINKDIR parameters are moved to a new <bsd.shlib.mk>; see bsd.README
for usage details.
Defaults to the directory determined by the _SRC_TOP_ logic (if != ""),
and the BSDSRCDIR.
NETBSDSRCDIR has been provided for use by the various NetBSD source
Makefiles to find the top of the NetBSD source tree, and isn't
affected by the inheritance properties of _SRC_TOP_, nor does it
have the magic BSDOBJDIR baggage that BSDSRCDIR is stuck with.
