Hello,
This change introduces configury infrastructure allowing the
production of shared libraries for VxWorks, amenable to use with
non-static rtps (linked with "-non-static").
The ability to produce PIC code is not a given on all VxWorks
configurations, so activating this has to be explicitly requested
by configuring with --enable-shared
(https://gcc.gnu.org/pipermail/gcc-patches/2022-September/602523.html).
This requirement is then leveraged to factorize the configuration
processing in a mostly cpu independant manner, which makes maintenance
a lot easier.
When activated, shared libs are built for the rtp mode only
(the only kind of entity for which they are supported by the
VxWorks environment), for code model != large at this stage as
large and PIC still don't play well together.
We have been using this for about a year with gcc-11 based toolchains,
with support activated for aarch64, x86_64 and ppc64-vxworks7r2, and
not activated for the corresponding 32bit variants (arm, i686, ppc).
Aarch64 proved an interesting challenge with the gcc/gcc_eh split
for lse features.
I obtained good test results with a gcc-12 based compiler for ppc64
and could get a successful sanity check build with mainline for that
cpu as well.
Will commit to mainline shortly.
Cheers,
Olivier

Subject: [PATCH 2/2] Generic configury support for shared libs on VxWorks
This change adds the configury bits to activate the build of
shared libs on VxWorks ports configured with --enable-shared,
for libraries variants where this is generally supported (rtp,
code model !large - currently not compatible with -fPIC).
Set lt_cv_deplibs_check_method in libtool.m4, so the build of
libraries know how to establish dependencies. This is useful in
configurations such as aarch64 where proper support of LSE relies
on accurate dependency information between libstdc++ and libgcc_s
to begin with.
Regenerate configure scripts to reflect libtool.m4 change.

Sorry, I forgot to cc libstdc++ on
https://gcc.gnu.org/pipermail/gcc-patches/2022-October/603182.html
which includes a regen of libstdc++-v3/configure after an update
libtool.m4.
Not committed yet.
With Kind Regards,
Olivier
