Created attachment 45381

gcc9-pr88331.patch

I don't see how that could ever work when assign_stack_local_1 is called from
anywhere but the expand pass, one can't emit random code somewhere blindly
otherwise (e.g. from the RA).  I think for now it is best to revert to previous
behavior when it isn't called during expansion, and if really needed, we can
figure out a way for GCC10 how to tell the RA it should emit the alignment
itself.

While trying to compile GCC trunk (commit

(https://gcc.gnu.org/bugzilla/show_bug.cgi?id=88331#c6)
