2017-09-18Move computation of SLP_TREE_NUMBER_OF_VEC_STMTSRichard Sandiford4-49/+66
Previously SLP_TREE_NUMBER_OF_VEC_STMTS was calculated while scheduling an SLP tree after analysis, but sometimes it can be useful to know the value during analysis too. This patch moves the calculation to vect_slp_analyze_node_operations instead. 2017-09-18 Richard Sandiford <richard.sandiford@linaro.org> Alan Hayward <alan.hayward@arm.com> David Sherwood <david.sherwood@arm.com> gcc/ * tree-vectorizer.h (vect_slp_analyze_operations): Replace parameters with a vec_info *. * tree-vect-loop.c (vect_analyze_loop_operations): Update call accordingly. * tree-vect-slp.c (vect_slp_analyze_node_operations): Add vec_info * parameter.

2017-09-18Fix an SVE failure in the Fortran matmul* testsRichard Sandiford2-0/+12
The vectoriser was calling vect_get_smallest_scalar_type without having proven that the type actually is a scalar. This seems to be the intended behaviour: the ultimate test of whether the type is interesting (and hence scalar) is whether an associated vector type exists, but this is only tested later. The patch simply makes the function cope gracefully with non-scalar inputs. 2017-09-18 Richard Sandiford <richard.sandiford@linaro.org> Alan Hayward <alan.hayward@arm.com> David Sherwood <david.sherwood@arm.com> gcc/ * tree-vect-data-refs.c (vect_get_smallest_scalar_type): Cope with types that aren't in fact scalar.

2017-09-18Include phis in SLP unrolling calculationRichard Sandiford4-27/+73
Without this we'd pick an unrolling factor based purely on longs, ignoring the ints. It's posssible that vect_get_smallest_scalar_type should also handle shifts, but I think we'd still want this as a belt-and-braces fix. 2017-09-18 Richard Sandiford <richard.sandiford@linaro.org> gcc/ * tree-vect-slp.c (vect_record_max_nunits): New function, split out from...

2017-09-18Fix vectorizable_mask_load_store handling of invariant masksRichard Sandiford4-2/+24
vectorizable_mask_load_store was not passing the required mask type to vect_get_vec_def_for_operand. This doesn't matter for masks that are defined in the loop, since their STMT_VINFO_VECTYPE will be what we need anyway. But it's not possible to tell which mask type the caller needs when looking at an invariant scalar boolean. As the comment above the function says: In case OP is an invariant or constant, a new stmt that creates a vector def needs to be introduced. VECTYPE may be used to specify a required type for vector invariant. This fixes the attached testcase for SVE. 2017-09-18 Richard Sandiford <richard.sandiford@linaro.org> gcc/ * tree-vect-stmts.c (vectorizable_mask_load_store): Pass mask_vectype to vect_get_vec_def_for_operand when getting the mask operand. gcc/testsuite/ * gfortran.dg/vect/mask-store-1.f90: New test. From-SVN: r252932
2017-09-18Fix type of bitstart in vectorizable_live_operationRichard Sandiford2-1/+8
This patch changes the type of the multiplier applied by vectorizable_live_operation from unsigned_type_node to bitsizetype, which matches the type of TYPE_SIZE and is the type expected of a BIT_FIELD_REF bit position. This is shown by existing tests when SVE is added. 2017-09-18 Richard Sandiford <richard.sandiford@linaro.org> Alan Hayward <alan.hayward@arm.com> David Sherwood <david.sherwood@arm.com> gcc/ * tree-vect-loop.c (vectorizable_live_operation): Fix type of bitstart.

2017-09-18Fix vectorizable_live_operation handling of vector booleansRichard Sandiford2-1/+10
vectorizable_live_operation needs to use BIT_FIELD_REF to extract one element of a vector. For a packed vector boolean type, the number of bits to extract should be taken from TYPE_PRECISION rather than TYPE_SIZE. This is shown by existing tests once SVE is added. 2017-09-18 Richard Sandiford <richard.sandiford@linaro.org> Alan Hayward <alan.hayward@arm.com> David Sherwood <david.sherwood@arm.com> gcc/ * tree-vect-loop.c (vectorizable_live_operation): Fix element size calculation for vector booleans.

2017-09-18Invoke vectorizable_live_operation in a consistent wayRichard Sandiford2-26/+44
vect_transform_stmt calls vectorizable_live_operation for each live statement in an SLP node, but vect_analyze_stmt only called it the once. This patch makes vect_analyze_stmt consistent with vect_transform_stmt, which should be a bit more robust, and also means that a later patch can use slp_index when deciding validity. 2017-09-18 Richard Sandiford <richard.sandiford@linaro.org> Alan Hayward <alan.hayward@arm.com> David Sherwood <david.sherwood@arm.com> gcc/ * tree-vect-stmts.c (can_vectorize_live_stmts): New function, split out from...

2017-09-18[RS6000] PR81996, __builtin_return_address(0) failsAlan Modra2-13/+19
rs6000_return_addr assumes that the stack link is at frame+0, which is true for count>0. For count==0, rs6000_return_addr is called with frame==frame_pointer_rtx and the stack link is *not* at frame+0 if -fstack-protector-all or -fsanitize=address because rs6000.h sets FRAME_GROWS_DOWNWARD for those options. PR target/81996 * gcc/config/rs6000/rs6000.c (rs6000_return_addr): Use stack_pointer_rtx for count 0. Update comments. Break up large rtl expression. From-SVN: r252901
