Hi all,
the attached patch now handles -fcoarray=single and access to the local
image like no coarray access, using the same check a before.
Actually, I think we could remove the if (..coarray..) check completely:
For 'single', it is like no coarrays; for 'lib' both AA[remote] =... and
"AA = ... AA[remove]" will create a function call and uses already
temporaries. I don't know what 'native'/'threads' does – but either it
the image index is different, then no temporary is needed at all – or it
is the same (in particular: this_image / not present), but then the
noncoarray analysis would work.
That analysis is correct, also as far as the shared memory coarray goes
(where you do offsets as an extra dimension, either it points to the
same memory or to different memory).
So, while your patch is OK, I think a simple removal of the test
is also OK.
Take your pick :-)
Best regards
Thomas
