Subject: Re: [GRAPHITE, PATCH] Loop unroll
At this point pbb-transformed has two basic maps, one is the mapping for
unroll and jam,
and one for the full tile for the striped dimension. Introduce a check that
differentiate
between them as the image of one maps should be included in the other.
I didn't do a full review (and I
Many thanks. Here is the new patch that fixes the main problem of the previous
one
(i.e separation of the loop after unroll and jam) as well as the problems raised
by you (see comments below).
Now the code with the separation class option looks:
ISL AST generated by ISL:
{
for (int c0 = 0;
Changed the option to -floop-unroll-and jam as you suggested.
The patch takes advantage of the new isl based code generator introduced
recently
in GCC (in fact of the possible options for building the AST).
The code generated for this optimization in the case of non-constant loop

I'm not sure if Tobi or Albert have told you, but the separation_class
option
is going to be phased out since its design is fundamentally flawed.
If you can't wait until isl-0.15, then I guess you have no choice but
to use

This is the patch for unroll and jam optimizations. It is based on the
