[CI-NOTIFY]: TCWG Bisect tcwg_gnu/gnu-master-arm-check_bootstrap - Build # 73 - Successful!

by ci_notify＠linaro.org

Successfully identified regression in *gcc* in CI configuration tcwg_gnu/gnu-master-arm-check_bootstrap. So far, this commit has regressed CI configurations: - tcwg_gnu/gnu-master-arm-check_bootstrap Culprit: <cut> commit 7d8211603a3d04384812b481b0ae01205a287a72 Author: Richard Biener <rguenther(a)suse.de> Date: Wed Jun 30 16:28:50 2021 +0200 tree-optimization/101178 - handle VEC_PERM in SLP permute propagation This adds handling of VEC_PERM nodes to SLP permute propagation. Previously VEC_PERM acted as forced materialization of incoming permutes since it is a good place to do that (with the constraint of those only appearing for two-operator nodes). The following patch, in addition to supporting (but not forcing) this, enables VEC_PERM nodes acting as "any" permute on the outgoing side since they also can consume arbitrary permutes on that side. This again (meh) changes how we represent permutes and materialization on the graph vertices now explicitely having the common incoming permute as well as an outgoing permute and in case both are different the vertex acts as materialization point of the incoming permute. 2021-06-30 Richard Biener <rguenther(a)suse.de> PR tree-optimization/101178 * tree-vect-slp.c (slpg_vertex::materialize): Remove.

Previously VEC_PERM acted as forced materialization of incoming permutes since it is a good place to do that (with the constraint of those only appearing for two-operator nodes). The following patch, in addition to supporting (but not forcing) this, enables VEC_PERM nodes acting as "any" permute on the outgoing side since they also can consume arbitrary permutes on that side. This again (meh) changes how we represent permutes and materialization on the graph vertices now explicitely having the common incoming permute as well as an outgoing permute and in case both are different the vertex acts as materialization point of the incoming permute. 2021-06-30 Richard Biener <rguenther(a)suse.de> PR tree-optimization/101178 * tree-vect-slp.c (slpg_vertex::materialize): Remove.

Successfully identified regression in *gcc* in CI configuration tcwg_bmk_gnu_tk1/gnu-release-arm-spec2k6-O3_LTO. So far, this commit has regressed CI configurations: - tcwg_bmk_gnu_tk1/gnu-release-arm-spec2k6-O3_LTO Culprit: <cut> commit 9b0365879b3c4917f5a2485a1fca8bb678484bfe Author: Richard Sandiford <richard.sandiford(a)arm.com> Date: Mon Oct 7 08:39:12 2019 +0000 [IRA] Handle fully-tied destinations in a similar way to earlyclobbers IRA's make_early_clobber_and_input_conflicts checks for cases in which an output operand is likely to be an earlyclobber and an input operand is unlikely to be tieable with it. If so, the allocno for the output conflicts with the allocno for the input. This seems to work well. However, a similar situation arises if an output operand is likely to be tied to one of a set of input operands X and if another input operand has a different value from all of the operands in X. E.g. if we have: 0: "=r, r" 1: "0, r" 2: "r, 0" 3: "r, r" operand 0 will always be tied to operand 1 or operand 2, so if operand 3 is different from them both, operand 0 acts like an earlyclobber as far as operand 3 (only) is concerned. The same is true for operand 2 in: 0: "=r" 1: "0" 2: "r" In the second example, we'd normally have a copy between operand 1 and operand 0 if operand 1 dies in the instruction, and so there's rarely a problem. But if operand 1 doesn't die in the instruction, operand 0 still acts as an earlyclobber for operand 2 (if different from operand 1), since in that case LRA must copy operand 1 to operand 0 before the instruction. As the existing comment says: Avoid introducing unnecessary conflicts by checking classes of the constraints and pseudos because otherwise significant code degradation is possible for some targets. I think that's doubly true here. E.g. it's perfectly reasonable to have constraints like: 0: "=r, r" 1: "0, r" 2: "r, r" on targets like s390 that have shorter instructions for tied operands, but that don't want the size difference to influence RA too much. We shouldn't treat operand 0 as earlyclobber wrt operand 2 in that case. This patch therefore treats a normal tied non-earlyclobber output as being effectively earlyclobber wrt to an input if it is so for *all* preferred alternatives. 2019-10-07 Richard Sandiford <richard.sandiford(a)arm.com> gcc/ * ira-lives.c (check_and_make_def_conflict): Handle cases in which DEF is not a true earlyclobber but is tied to a specific input operand, and so is effectively earlyclobber wrt inputs that have different values. (make_early_clobber_and_input_conflicts): Pass this case to the above.

The same is true for operand 2 in: 0: "=r" 1: "0" 2: "r" In the second example, we'd normally have a copy between operand 1 and operand 0 if operand 1 dies in the instruction, and so there's rarely a problem. But if operand 1 doesn't die in the instruction, operand 0 still acts as an earlyclobber for operand 2 (if different from operand 1), since in that case LRA must copy operand 1 to operand 0 before the instruction. As the existing comment says: Avoid introducing unnecessary conflicts by checking classes of the constraints and pseudos because otherwise significant code degradation is possible for some targets. I think that's doubly true here. E.g. it's perfectly reasonable to have constraints like: 0: "=r, r" 1: "0, r" 2: "r, r" on targets like s390 that have shorter instructions for tied operands, but that don't want the size difference to influence RA too much. We shouldn't treat operand 0 as earlyclobber wrt operand 2 in that case. This patch therefore treats a normal tied non-earlyclobber output as being effectively earlyclobber wrt to an input if it is so for *all* preferred alternatives. 2019-10-07 Richard Sandiford <richard.sandiford(a)arm.com> gcc/ * ira-lives.c (check_and_make_def_conflict): Handle cases in which DEF is not a true earlyclobber but is tied to a specific input operand, and so is effectively earlyclobber wrt inputs that have different values.

There are a few places where we multiply a cost by a number N, i.e. unsigned N = isScalarAfterVectorization(I, VF) ? VF.getKnownMinValue() : 1; return N * TTI.getArithmeticInstrCost(... After some investigation it seems that there are only these cases that occur in practice: 1. VF is a scalar, in which case N = 1. 2. VF is a vector. We can only get here if: a) the instruction is a GEP/bitcast/PHI with scalar uses, or b) this is an update to an induction variable that remains scalar. I have changed the code so that N is assumed to always be 1. For GEPs the cost is always 0, since this is calculated later on as part of the load/store cost. PHI nodes are costed separately and were never previously multiplied by VF. For all other cases I have added an assert that none of the users needs scalarising, which didn't fire in any unit tests. Only one test required fixing and I believe the original cost for the scalar add instruction to have been wrong, since only one copy remains after vectorisation. I have also added a new test for the case when a pointer PHI feeds directly into a store that will be scalarised as we were previously never testing it.
