POLY_BB represents a blackbox in the polyhedral model.
poly_scattering_p poly_bb::_original |
The original scattering.
poly_scattering_p poly_bb::_saved |
A copy of the transformed scattering.
poly_scattering_p poly_bb::_transformed |
The transformed scattering.
void* poly_bb::black_box |
Pointer to a basic block or a statement in the compiler.
Referenced by same_pdr_p().
isl_set* poly_bb::domain |
The iteration domain of this bb. The layout of this polyhedron is I|G with I the iteration domain, G the context parameters.
Example:
for (i = a - 7*b + 8; i <= 3*a + 13*b + 20; i++) for (j = 2; j <= 2*i + 5; j++) for (k = 0; k <= 5; k++) S (i,j,k)
Loop iterators: i, j, k Parameters: a, b
| i >= a - 7b + 8 | i <= 3a + 13b + 20 | j >= 2 | j <= 2i + 5 | k >= 0 | k <= 5
The number of variables in the DOMAIN may change and is not related to the number of loops in the original code.

bool poly_bb::is_reduction |
True when this PBB contains only a reduction statement.
isl_map* poly_bb::saved |
isl_map* poly_bb::schedule |
scop_p poly_bb::scop |
Pointer to the SCOP containing this PBB.
