            Bug ID: 103739
           Summary: Bootstrap broken on powerpc64-linux
           Product: gcc
           Version: unknown
            Status: UNCONFIRMED

          Priority: P3
         Component: d
          Assignee: ibuclaw at gdcproject dot org

make[3]: *** [d/access.o] Error 1

This is with --enable-languages=all.  This should not build D if that cannot
work (if that is what the problem is, I have no idea).

Why is the library not installed alongside the host compiler though?  The D
core runtime compiles and works well on powerpc64-linux.

Hi!

I have no idea why not.

$ gdc --version
gdc (GCC) 9.3.1 20200410

and it says

Configured with: /home/segher/src/gcc/configure --prefix=/home/segher/tot
--enable-languages=c,c++,fortran,ada,d,objc,obj-c++ --disable-libgomp

Seems to be just gcc-9 - bootstrapped from the tip of releases/gcc-10 just
fine.  Probably something that should have been backported wasn't.  I'll have a
look to see what that was.

Thanks.  But the point of this PR is that bootstrapping trunk is broken.
That needs fixing some way.

It's working when you use gcc-10 or later as the baseline, you're using gcc-9
and it isn't.
