This patch to the Go testsuite driver changes it to handle +build
lines correctly, which is to say, in the same way that they are
handled by the upstream test driver. Update several tests from the
upstream repo to use "gc" and "!gccgo" as appropriate so that tests
continue to pass. This cleans up

This patch enables MVE vshlq instructions for auto-vectorization.
The existing mve_vshlq_n_ is kept, as it takes a single

We move the vashl3 insn from neon.md to an expander in

This patch adds new movmisalign_mve_load and store patterns for
MVE to help vectorization. They are very similar to their Neon

Indeed MVE supports less vectors modes than Neon, so we use
the MVE_VLD_ST iterator where Neon uses VQX.

With the introduction of C++20 modules and libcody, cc1plus and
cc1objplus gained a dependency on the socket functions. Before those
were merged into libc in Solaris 11.4, one needed to link with -lsocket -lnsl
on Solaris, so that merge broke the Solaris 11.3 build.

Hi Tobias,
Thanks for the quick review!
It helps when I'm on holiday :-)

With multi unit naming scheme (e.g. "unit.1.ada" and "unit.2.ada"
instead of "unit.ads" and "unit.adb") the Multiple_Unit_Index global
variable keeps the current index number. It is only assigned by routines
that return non-negative numbers.

CM_Membership is used implicitly by some tagged related constructs, and

There is a fallback code in gigi in case the front-end constructs
trees referencing non existing record fields. At this stage, it's
safer and cleaner to ensure that the front-end never generates such
references, and eventually replace the code in gigi by a gcc_unreachable().
