| 2019-12-31 | Fix SSA update when vectorisation adds a vdef to a read-only loop | Richard Sandiford | 4 | -4/+132 | |
| This patch fixes an awkward corner case in which: (a) we apply if-conversion to a loop; (b) the original scalar loop doesn't have a vdef, and thus doesn't need a virtual phi; (c) the vectorised main loop does need a vdef and a virtual phi (see below); (d) we also vectorise the epilogue; and (e) the vectorised epilogue still needs a scalar epilogue The specific case in which (c) applies is if a read-only loop is vectorised using IFN_LOAD_LANES, which uses clobber statements to mark the lifetime of the temporary array. The vectoriser relies on the SSA renamer to update virtual operands. All would probably be well if it postponed this update until after it had vectorised both the main loop and the epilogue loop. However, when vectorising the epilogue, vect_do_peeling does: create_lcssa_for_virtual_phi (loop); update_ssa (TODO_update_ssa_only_virtuals); (with "loop" in this case being the to-be-vectorised epilogue loop). So the vectoriser puts the virtual operand into SSA form for the vectorised main loop as a separate step, during the early stages of vectorising the epilogue. I wasn't sure at first why that update_ssa was there. It looked initially like it was related to create_lcssa_for_virtual_phi, which seemed strange when create_lcssa_for_virtual_phi keeps the SSA form up-to-date. But before r241099 it had the following comment, which AFAICT is still the reason: /* We might have a queued need to update virtual SSA form. As we delete the update SSA machinery below after doing a regular incremental SSA update during loop copying make sure we don't lose that fact. ??? Needing to update virtual SSA form by renaming is unfortunate but not all of the vectorizer code inserting new loads / stores properly assigns virtual operands to those statements. */ The patch restores that comment since IMO it's helpful. (a), (d) and (e) mean that we copy the original un-if-converted scalar loop to act as the scalar epilogue. The update_ssa above means that this copying needs to cope with any new virtual SSA names in the main loop. The code to do that (reasonably) assumed that one of two things was true: (1) the scalar loop and the vector loops don't have vdefs, and so no virtual operand update is needed. The definition that applies on entry to the loops is the same in all cases. (2) the scalar loop and the vector loops have virtual phis, and so -- after applying create_lcssa_for_virtual_phi on the to-be-vectorised epilogue loop -- the virtual operand update can be handled in the same way as for normal SSA names. But (b) and (c) together mean that the scalar loop and the still-to-be-vectorised epilogue loop have no virtual phi that (2) can use. We'd therefore keep the original vuses when duplicating, rather than updating them to the definition that applies on exit from the epilogue loop. (Since the epilogue is still unvectorised and has no vdefs, the definition that applies on exit is the same as the one that applies on entry.) This patch therefore adds a third case: the scalar loop and to-be-vectorised epilogue have no virtual defs, but the main loop does. 2019-12-31 Richard Sandiford <richard.sandiford@arm.com> gcc/ * tree-vect-loop-manip.c (create_lcssa_for_virtual_phi): Return the incoming virtual operand definition.

| 2019-12-29 | Unshare DR_STEP before gimplifying it | Richard Sandiford | 4 | -2/+19 | |
| In this testcase we use an unmasked SVE loop with an Advanced SIMD epilogue (because we don't yet support fully-masked downward loops). The main loop uses a gather load for the strided access while the epilogue loop builds the access from scalars instead. In both cases we gimplify expressions based on the DR_STEP and insert them in the loop preheader. The problem was that the gather load code didn't copy the DR_STEP before gimplifying it, meaning that the epilogue loop tried to reuse a result from the (non-dominating) main loop preheader. It looks at first glance like there could be other instances of this too, but this patch just deals with the gather/scatter case. 2019-12-29 Richard Sandiford <richard.sandiford@arm.com> gcc/ * tree-vect-stmts.c (vect_get_strided_load_store_ops): Copy DR_STEP before gimplifying it. gcc/testsuite/ * gcc.dg/vect/vect-strided-epilogue-1.c: New test.
