Hi Paul,
This is a complete rework of the patch and of the original mechanism
for adding caf token fields and finding them.
In this patch, the token fields are added to the derived types after
all the components have been resolved. This is done so that all the
tokens appear at the very end of the derived type, including the
hidden string lengths. This avoids the present situation, where the
token appears immediately after its associated component such that the
the derived types are not compatible with modules or libraries
compiled without -fcoarray selected. All trans-types has to do now is
to find the component and have the component token field point to its
backend_decl. PR83319 is fixed by unconditionally adding the token
field to the descriptor, when -fcoarray=lib whatever the value of
codimen.
This looks very good.
I just have one question: Will this break binary compatibility for
the 7-branch? Or will this only break compatibility for something
that never worked anyway?
Regards
Thomas
