We generally do not want to implement language extensions. It takes a
strong argument to convince us. Also, as a pra

Hi,
I have 2 ideas about C++ language, maybe they could be implemented as
GCC C++ extensions (Microsoft has many his own and no one complains). :-)
If it doesn't have them already (I don't know, but I have never heard
about this ideas).
1. void as first class type
Current status of void is s

You're right: that was exactly the difference. It turns out I was
setting the third and fourth operands in the ARRAY_REF to what I
thought were sensible values. Setting them to NULL instead made the
ADDR_EXPR satisfy is_gimple_min_invariant() and fixed the whole mess.
Thanks again for looking at

On my nightly tester I force libstdc++ to be built with -flto enabled using
$ make check RUNTESTFLAGS=--target_board=unix/"\{-flto/-O2,-fwhopr/-O2\}"
Recently, this started showing 17 regressions that we don't see in
other testsuites. It would be useful if we would run libstdc++ with
-flto as we

Ah, you'll probably have to re-run configure and rebuild the cross compi
../configure --target=i370-mvspdp --prefix=/devel/mvscross
--with-sysroot=/devel/mvshead
--enable-languages=c
plus make and make install
then I went to
mvscross/bin and renamed i370-mvspdp-gcc to i370-mvspdp-xxx
and replaced it with a script that does:
i370-mvspdp-xxx -S $*
