Hi!

We've been (t)asked to enable (portions of) GCC/Fortran I/O for nvptx
offloading, which means building a normal (non-'LIBGFOR_MINIMAL')
configuration of libgfortran.  One prerequisite patch, based on WIP work
by Andrew Stubbs, is: "nvptx, libgcc: Stub unwinding implementation", see
attached.  This I've just pushed to devel/omp/gcc-12 branch in
commit 26d3146736218ccaaaafdaba4da1edf969bc190d, and would like to push
to master branch once other pending GCC patches have been accepted.


Grüße
 Thomas
