Nathan, I haven't looked too deeply into your tile changes yet. Do you
know of the fortran FE is doing anything wrong? I haven't checked if
it's lowering the tile clause in the proper format yet.
thanks for working on this. The problems I noticed (& fixed) in the C/c++
frontends were
1) map '*' onto integer_zero_node -- this makes my changes cleaner.
2) should only accept integer constant expressions (whatever the fortran
equivalent of that is). While runtime values could be made to work, the std
doesn't require that, and it would perform quite badly due to the lack of
constant folding
3) failing to parse nested loops correctly. It only parsed the outermost loop
as a parallel loop. Tile in many ways looks like collapse
If those could be addressed that'd be great -- it doesn't need my tile WIP to do
that.
