--- Comment #9 from spop at gcc dot gnu dot org 2010-02-09 04:57 --- Hi, As suggested by Zdenek, here is a patch that lowers the cost of the IV when it is compared against zero in a condition. The fragile part of this patch is that it lowers the cost by a magical constant 10. Would there be a more appropriate way to compute the effect, or a better constant?

[Bug tree-optimization/42637] [4.5 Regression][graphite] wrong code for -floop-interchange -ftree-loop-distribution
--- Comment #5 from spop at gcc dot gnu dot org 2010-01-16 22:17 --- I have looked again to this function, and I just realized that there were changes to one of the functions of the data dependence test: build_pairwise_scheduling_inequality used to build strict inequalities for the lexicographic comparison, and then Tobias changed it like this: -cstr = build_pairwise_constraint (dim, pos, pos + offset, 0, PPL_CONSTRAINT_TYPE_GREATER_THAN); +cstr = build_pairwise_constraint (dim, pos, pos + offset, -1, + PPL_CONSTRAINT_TYPE_GREATER_OR_EQUAL); else -cstr = build_pairwise_constraint (dim, pos, pos + offset, 0, PPL_CONSTRAINT_TYPE_LESS_THAN); +cstr = build_pairwise_constraint (dim, pos, pos + offset, 1, + PPL_CONSTRAINT_TYPE_LESS_OR_EQUAL); This is wrong. This change was done when we decided to remove the use of the NNC (Non-Necessarily Closed) polyhedra into C (Closed) polyhedra, that do not allow the strict inequalities. I am working on a fix for this PR.

[Bug tree-optimization/42637] [4.5 Regression][graphite] wrong code for -floop-interchange -ftree-loop-distribution
--- Comment #4 from spop at gcc dot gnu dot org 2010-01-15 01:20 --- The problem here is that the loop invariant motion moves rt(i,j) into a temporary outside the innermost loop: real*8 rt(6,6),r(6,6),rtt(6,6) do i=1,6 do j=1,6 t = rt(i,j) do ia=1,6 rtt(i,ia)=t*r(j,ia)+rtt(i,ia) end do end do end do and then we get the cleanup before graphite translating this into an array: do i=1,6 do j=1,6 cross_bb[0] = rt(i,j) do ia=1,6 rtt(i,ia)=cross_bb[0]*r(j,ia)+rtt(i,ia) end do end do end do Then the loop interchange would ask for loop distribution when it considers the loops 'j' and 'ia', and from the original LST we get: original_lst ( (root 0 (loop 0 (loop 0 stmt_4 1 (loop 0 stmt_5) transformed_lst ( (root 0 (loop 1 0 (loop 2 0 stmt_4) 1 (loop 3 0 (loop 4 0 stmt_5) that is then validated as legal by the graphite_legal_transform. The problem seems to be in the build_lexicographically_gt_constraint that does not add the information first instance of stmt_5 is executed after the last instance of stmt_4 in loop 2. We would have then a write into cross_bb[0] for all the iterations of loop 2: cross_bb[0] = rt(i,0) cross_bb[0] = rt(i,1) cross_bb[0] = rt(i,2) cross_bb[0] = rt(i,3) cross_bb[0] = rt(i,4) cross_bb[0] = rt(i,5) and then only we would read the value of cross_bb[0] in stmt_5: = cross_bb[0] * ... = cross_bb[0] * ... = cross_bb[0] * ... = cross_bb[0] * ... = cross_bb[0] * ... = cross_bb[0] * ... In the original program we would have had these writes and reads interleaved like this: cross_bb[0] = rt(i,0) = cross_bb[0] * ... cross_bb[0] = rt(i,1) = cross_bb[0] * ... cross_bb[0] = rt(i,2) = cross_bb[0] * ... cross_bb[0] = rt(i,3) = cross_bb[0] * ... cross_bb[0] = rt(i,4) = cross_bb[0] * ... cross_bb[0] = rt(i,5) = cross_bb[0] * ...

[Bug tree-optimization/42732] [graphite] ICE: verify_ssa failed
--- Comment #2 from spop at gcc dot gnu dot org 2010-01-13 19:01 --- pdv_d.f:89:0: error: definition in block 40 does not dominate use in block 212 for SSA_NAME: prephitmp.28_439 in statement: D.2771_606 = D.2770_605 = prephitmp.28_439; The error comes from the fact that we are not clearing the scev information anymore in between the code generation of two scops. In this particular case, we have two scops, the second scop contains a loop for which the number of iterations is a variable computed in the first scop, and because we do not update the niter/scev info we keep referring to the old SSA_NAME, prephitmp.28_439. A solution would be to rename all the scev info based on the rename_map that is computed by the translation of the first scop. I am working on a patch to do that.

The problem is in the code generation of the following CLAST:
if (7*T_6%8 == 0) {
...
}
where T_6 has a pointer type, and build refuses to construct a MULT_EXPR with a
pointer type.
I think that for this kind of expressions we will have to stop gloog, remove
the code that we generated, and leave the non transformed version.
