2021-11-30vect: Support gather loads with SLPRichard Sandiford1-34/+30
This patch adds SLP support for IFN_GATHER_LOAD. Like the SLP support for IFN_MASK_LOAD, it works by treating only some of the arguments as child nodes. Unlike IFN_MASK_LOAD, it requires the other arguments (base, scale, and extension type) to be the same for all calls in the group. It does not require/expect the loads to be in a group (which probably wouldn't make sense for gathers). I was worried about the possible alias effect of moving gathers around to be part of the same SLP group. The patch therefore makes vect_analyze_data_ref_dependence treat gathers and scatters as a top-level concern, punting if the accesses aren't completely independent and if the user hasn't told us that a particular VF is safe. I think in practice we already punted in the same circumstances; the idea is just to make it more explicit. gcc/ PR tree-optimization/102467 * doc/sourcebuild.texi (vect_gather_load_ifn): Document. * tree-vect-data-refs.c (vect_analyze_data_ref_dependence): Commonize safelen handling.

2021-11-30vect: Fix SVE mask_gather_load/store_store testsRichard Sandiford1-0/+1
If-conversion now applies rewrite_to_defined_overflow to the address calculation in an IFN_MASK_LOAD. This means that we end up with: cast_base = (uintptr_t) base; uncast_sum = cast_base + offset; sum = (orig_type *) uncast_sum; If the target supports IFN_MASK_GATHER_LOAD with pointer-sized offsets for the given vectype, we wouldn't look through the sum cast and so would needlessly vectorise the uncast_sum addition. This showed up as several failures in gcc.target/aarch64/sve. gcc/ * tree-vect-data-refs.c (vect_check_gather_scatter): Continue processing conversions if the current offset is a pointer.
2021-11-30vect: Pass mode to gather/scatter testsRichard Sandiford1-2/+2
vect_check_gather_scatter had a binary “does this target support internal gather/scatter functions” test. This dates from the time when we only handled gathers and scatters via direct target support, with x86_64 using built-in functions and aarch64 using IFNs. But now that we can emulate gathers, we need to check whether the gather for a particular mode is going to be emulated or not. Without this, enabling SVE regresses emulated Advanced SIMD gather sequences in cases where SVE isn't used. Livermore kernel 15 can now be vectorised with Advanced SIMD when SVE is enabled. gcc/ * genopinit.c (main): Turn supports_vec_gather_load and supports_vec_scatter_store into signed char arrays and remove supports_vec_gather_load_cached and supports_vec_scatter_store_cached. * optabs-query.c (supports_vec_convert_optab_p): Add a mode parameter.

2021-10-26Move negative stride bias out of dr_misalignmentRichard Biener1-19/+39
This moves applying of a bias for negative stride accesses out of dr_misalignment in favor of a more general optional offset argument. The negative bias is now computed by get_load_store_type and applied accordingly to determine the alignment support scheme. Likewise the peeling/versioning code is adjusted albeit that still assumes we'll end up with VMAT_CONTIGUOUS_DOWN or VMAT_CONTIGUOUS_REVERSE but at least when not so (VMAT_STRIDED_SLP is one possibility) then get_load_store_type will _not_ falsely report an aligned access but instead an access with known misalignment.

2021-10-19Remove check_aligned parameter from vect_supportable_dr_alignmentRichard Biener1-18/+23
There are two calls with true as parameter, one is only relevant for the case of the misalignment being unknown which means the access is never aligned there, the other is in the peeling hash insert code used conditional on the unlimited cost model which adds an artificial count. But the way it works right now is that it boosts the count if the specific misalignment when not peeling is unsupported - in particular when the access is currently aligned we'll query the backend with a misalign value of zero. I've changed it to boost the peeling when unknown alignment is not supported instead and noted how we could in principle improve this. 2021-10-19 Richard Biener <rguenther@suse.de> * tree-vectorizer.h (vect_supportable_dr_alignment): Remove check_aligned argument. * tree-vect-data-refs.c (vect_supportable_dr_alignment): Likewise.

2021-10-12vectorizer: Fix up -fsimd-cost-model= handlingJakub Jelinek1-4/+6
> * testsuite/libgomp.c++/scan-10.C: Add option -fvect-cost-model=cheap. I don't think this is the right thing to do. This just means that at some point between 2013 when -fsimd-cost-model has been introduced and now -fsimd-cost-model= option at least partially stopped working properly. As documented, -fsimd-cost-model= overrides the -fvect-cost-model= setting for OpenMP simd loops (loop->force_vectorize is true) if specified differently from default. In tree-vectorizer.h we have: static inline bool unlimited_cost_model (loop_p loop) { if (loop != NULL && loop->force_vectorize && flag_simd_cost_model != VECT_COST_MODEL_DEFAULT) return flag_simd_cost_model == VECT_COST_MODEL_UNLIMITED; return (flag_vect_cost_model == VECT_COST_MODEL_UNLIMITED); } and use it in various places, but we also just use flag_vect_cost_model in lots of places (and in one spot use flag_simd_cost_model, not sure if we are sure it is a force_vectorize loop or what). So, IMHO we should change the above inline function to loop_cost_model and let it return the cost model and then just reimplement unlimited_cost_model as return loop_cost_model (loop) == VECT_COST_MODEL_UNLIMITED; and then adjust the direct uses of the flag and revert these changes. 2021-10-12 Jakub Jelinek <jakub@redhat.com> gcc/ * tree-vectorizer.h (loop_cost_model): New function.

2021-09-27Allow different vector types for stmt groupsRichard Biener1-108/+119
This allows vectorization (in practice non-loop vectorization) to have a stmt participate in different vector type vectorizations. It allows us to remove vect_update_shared_vectype and replace it by pushing/popping STMT_VINFO_VECTYPE from SLP_TREE_VECTYPE around vect_analyze_stmt and vect_transform_stmt. For data-ref the situation is a bit more complicated since we analyze alignment info with a specific vector type in mind which doesn't play well when that changes. So the bulk of the change is passing down the actual vector type used for a vectorized access to the various accessors of alignment info, first and foremost dr_misalignment but also aligned_access_p, known_alignment_for_access_p, vect_known_alignment_in_bytes and vect_supportable_dr_alignment. I took the liberty to replace ALL_CAPS macro accessors with the lower-case function invocations. The actual changes to the behavior are in dr_misalignment which now is the place factoring in the negative step adjustment as well as handling alignment queries for a vector type with bigger alignment requirements than what we can (or have) analyze(d). vect_slp_analyze_node_alignment makes use of this and upon receiving a vector type with a bigger alingment desire re-analyzes the DR with respect to it but keeps an older more precise result if possible. In this context it might be possible to do the analysis just once but instead of analyzing with respect to a specific desired alignment look for the biggest alignment we can compute a not unknown alignment. The ChangeLog includes the functional changes but not the bulk due to the alignment accessor API changes - I hope that's something good. 2021-09-17 Richard Biener <rguenther@suse.de> PR tree-optimization/97351 PR tree-optimization/97352 PR tree-optimization/82426 * tree-vectorizer.h (dr_misalignment): Add vector type argument.

This removes adjusting alignment based on the vectorized accesses and instead keeps what was set on the original access.

When doing whole-function SLP we have to make sure the recorded base alignments we compute as the maximum alignment seen for a base anywhere in the function is actually valid at the point we want to make use of it. To make this work we now record the stmt the alignment was derived from in addition to the DRs innermost behavior and we use a dominance check to verify the recorded info is valid when doing BB vectorization. For this to work for groups inside a BB that are separate by a call that might not return we now store the DR analysis group-id permanently and use that for an additional check when the DRs are in the same BB. 2021-08-31 Richard Biener <rguenther@suse.de> PR tree-optimization/102139 * tree-vectorizer.h (vec_base_alignments): Adjust hash-map type to record a std::pair of the stmt-info and the innermost loop behavior.

2021-08-04Add emulated gather capability to the vectorizerRichard Biener1-10/+21
This adds a gather vectorization capability to the vectorizer without target support by decomposing the offset vector, doing sclar loads and then building a vector from the result. This is aimed mainly at cases where vectorizing the rest of the loop offsets the cost of vectorizing the gather. Note it's difficult to avoid vectorizing the offset load, but in some cases later passes can turn the vector load + extract into scalar loads, see the followup patch. On SPEC CPU 2017 510.parest_r this improves runtime from 250s to 219s on a Zen2 CPU which has its native gather instructions disabled (using those the runtime instead increases to 254s) using -Ofast -march=znver2 [-flto].

This places two hacks to avoid an old compile-time issue when vectorizing large permuted SLP groups with gaps where we end up emitting loads and IV adjustments for the gap as well and those have quite a high cost until they are eventually cleaned up. The first hack is to fold the auto-inc style IV updates early in the vectorizer rather than in the next forwprop pass which shortens the SSA use-def chains of the used IV.

2021-06-17Vectorization of BB reductionsRichard Biener1-5/+4
This adds a simple reduction vectorization capability to the non-loop vectorizer. Simple meaning it lacks any of the fancy ways to generate the reduction epilogue but only supports those we can handle via a direct internal function reducing a vector to a scalar. One of the main reasons is to avoid massive refactoring at this point but also that more complex epilogue operations are hardly profitable. Mixed sign reductions are for now fend off and I'm not finally settled with whether we want an explicit SLP node for the reduction epilogue operation. Handling mixed signs could be done by multiplying with a { 1, -1, .. } vector. Fend off are also reductions with non-internal operands (constants or register parameters for example). Costing is done by accounting the original scalar participating stmts for the scalar cost and log2 permutes and operations for the vectorized epilogue. -- SPEC CPU 2017 FP with rate workload measurements show (picked fastest runs of three) regressions for 507.cactuBSSN_r (1.5%), 508.namd_r (2.5%), 511.povray_r (2.5%), 526.blender_r (0.5) and 527.cam4_r (2.5%) and improvements for 510.parest_r (5%) and 538.imagick_r (1.5%). This is with -Ofast -march=znver2 on a Zen2. Statistics on CPU 2017 shows that the overwhelming number of seeds we find are reductions of two lanes (well - that's basically every associative operation). That means we put a quite high pressure on the SLP discovery process this way. In total we find 583218 seeds we put to SLP discovery out of which 66205 pass that and only 6185 of those make it through code generation checks. 796 of those are discarded because the reduction is part of a larger SLP instance. 4195 of the remaining are deemed not profitable to vectorize and 1194 are finally vectorized. That's a poor 0.2% rate. Of the 583218 seeds 486826 (83%) have two lanes, 60912 have three (10%), 28181 four (5%), 4808 five, 909 six and there are instances up to 120 lanes. There's a set of 54086 candidate seeds we reject because they contain a constant or invariant (not implemented yet) but still have two or more lanes that could be put to SLP discovery. 2021-06-16 Richard Biener <rguenther@suse.de> PR tree-optimization/54400 * tree-vectorizer.h (enum slp_instance_kind): Add slp_inst_kind_bb_reduc.

2020-12-31vect: Fix bogus alignment assumption in alias checks [PR94994]Richard Sandiford1-1/+1
This PR is about a case in which the vectoriser was feeding incorrect alignment information to tree-data-ref.c, leading to incorrect runtime alias checks. The alignment was taken from the TREE_TYPE of the DR_REF, which in this case was a COMPONENT_REF with a normally-aligned type. However, the underlying MEM_REF was only byte-aligned. This patch uses dr_alignment to calculate the (byte) alignment instead, just like we do when creating vector MEM_REFs. gcc/ PR tree-optimization/94994 * tree-vect-data-refs.c (vect_vfa_align): Use dr_alignment. gcc/testsuite/ PR tree-optimization/94994 * gcc.dg/vect/pr94994.c: New test.

2020-11-19vect: Add a “very cheap” cost modelRichard Sandiford1-2/+6
Currently we have three vector cost models: cheap, dynamic and unlimited. -O2 -ftree-vectorize uses “cheap” by default, but that's still relatively aggressive about peeling and aliasing checks, and can lead to significant code size growth. This patch adds an even more conservative choice, which for lack of imagination I've called “very cheap”. It only allows vectorisation if the vector code entirely replaces the scalar code. It also requires one iteration of the vector loop to pay for itself, regardless of how often the loop iterates. (If the vector loop needs multiple iterations to be beneficial then things are probably too close to call, and the conservative thing would be to stick with the scalar code.) The idea is that this should be suitable for -O2, although the patch doesn't change any defaults itself. I tested this by building and running a bunch of workloads for SVE, with three options: (1) -O2 (2) -O2 -ftree-vectorize -fvect-cost-model=very-cheap (3) -O2 -ftree-vectorize [-fvect-cost-model=cheap] All three builds used the default -msve-vector-bits=scalable and ran with the minimum vector length of 128 bits, which should give a worst-case bound for the performance impact. The workloads included a mixture of microbenchmarks and full applications. Because it's quite an eclectic mix, there's not much point giving exact figures. The aim was more to get a general impression. Code size growth with (2) was much lower than with (3). Only a handful of tests increased by more than 5%, and all of them were microbenchmarks. In terms of performance, (2) was significantly faster than (1) on microbenchmarks (as expected) but also on some full apps. Again, performance only regressed on a handful of tests. As expected, the performance of (3) vs. (1) and (3) vs. (2) is more of a mixed bag. There are several significant improvements with (3) over (2), but also some (smaller) regressions. That seems to be in line with -O2 -ftree-vectorize being a kind of -O2.5. The patch reorders vect_cost_model so that values are in order of increasing aggressiveness, which makes it possible to use range checks. The value 0 still represents “unlimited”, so “if (flag_vect_cost_model)” is still a meaningful check. gcc/ * doc/invoke.texi (-fvect-cost-model): Add a very-cheap model. * common.opt (fvect-cost-model=): Add very-cheap as a possible option.

2020-10-12optimize permutes in SLP, remove vect_attempt_slp_rearrange_stmtsRichard Biener1-1/+1
This introduces a permute optimization phase for SLP which is intended to cover the existing permute eliding for SLP reductions plus handling commonizing the easy cases. It currently uses graphds to compute a postorder on the reverse SLP graph and it handles all cases vect_attempt_slp_rearrange_stmts did (hopefully - I've adjusted most testcases that triggered it a few days ago). It restricts itself to move around bijective permutations to simplify things for now, mainly around constant nodes. As a prerequesite it makes the SLP graph cyclic (ugh). It looks like it would pay off to compute a PRE/POST order visit array once and elide all the recursive SLP graph walks and their visited hash-set. At least for the time where we do not change the SLP graph during such walk. I do not like using graphds too much but at least I don't have to re-implement yet another RPO walk, so maybe it isn't too bad. It now computes permute placement during iteration and thus should get cycles more obviously correct.

This is a follow up to commit 5c9669a0e6c respectively discussion https://gcc.gnu.org/pipermail/gcc-patches/2020-June/549132.html In case a type has a lower alignment than its size, ensure that we advance. For example, on s390x we have for a long double an alignment constraint of 8 bytes whereas the size is 16 bytes.
