Subject: [Patch, Fortran, OOP] PR 54917: [4.7/4.8 Regression] TRANSFER on polymorphic variable causes ICE

Hi all,

the attached patch implements support for polymorphic arguments to
TRANSFER. For details and discussion see the PR.

The patch was regtested successfully on x86_64-unknown-linux-gnu. Ok for trunk?

Btw, as part of the PR is a regression in 4.7 and trunk, I would like
to backport the target-memory.c part and the first test case to the
4.7 branch. Ok?

Cheers,
Janus
