"Bug 47046 - gcc.target/i386/sse4_1-movntdqa.c ICEs with -fgraphite-identity"
The problem here is that we are left with the following code to be
translated in the new representation following the transform that
Graphite has chosen:
D.2709_14 = j_33 * i_32;
D.2710_15 = D.2709_14 * i_32;
D.2711_16 = D.2710_15 * sign_34;
*D.2708_13 = D.2711_16;
In this particular case we have a nonlinear expression "i * i" for
which we have to generate code following the new graphite_iv variables.
The patch fixes the function that detects whether we are passing non
linear stuff to graphite: evolution_function_is_affine_p. It seems
like for the moment evolution_function_is_affine_p is testing whether
an evolution function is affine only in the innermost loop, without
looking recursively at what happens in outer loops.
The chrec for this case is: {0, +, {0, +, {1, +, 2}_1}_1}_2 and we are
testing whether the evolution is affine only for the loop_2, which is
true as we have {0, +, blah}_2 with blah invariant in loop_2.
The patch adds the recursive call to evolution_function_is_affine_p.
Bootstrapped and tested on amd64-linux.
