Dear all,
this follow-up patch reduces the number of front-end memleaks that pop
up during simplification of TRANSFER(), and adds the original testcase
from the PR. The fix consists mainly of a reordering of the code in
gfc_simplify_transfer, taking into account the knowledge of the rank
of the result.
The changes to target-memory.cc could have been done differently,
but these are also sensitive to the BOZ handling. The current
solution was the simplest one I found that does not regress.
Regression tested on x86_64-pc-linux-gnu. OK for mainline?
Thanks,
Harald
OK modulo one small nit:
