Hi all, the attached patch fixes an regression with TRANSFER, which was just reported today. The problem was that array-valued SOURCE arguments were not treated correctly.
To fix it properly, I had to make 'gfc_target_expr_size' behave
correctly for arrays and introduced an new function 'gfc_element_size'
(which, contrary to the former, returns the size of one array element
instead of the whole expression).
In the process I could also remove the small function 'size_array' and
had to make some more adjustments in simlify.c, in order to account
for the slightly modified (and now more consistent) behavior of
'gfc_target_expr_size'.
Regtested on x86_64-unknown-linux-gnu. Ok for trunk? 4.7/4.8?
Cheers,
Janus
