2018-12-18[testsuite] Enable vect_usad_char effective target for non-SVE aarch64Kyrylo Tkachov2-1/+9
In GCC 9 the aarch64 port learned how to do V16QImode SAD operations on signed and unsigned chars. But I had missed enabling the effective target for that. This patch enables that target for non-SVE aarch64. Two new tests now PASS on aarch64: gcc.dg/vect/slp-reduc-sad.c gcc.dg/vect/vect-reduc-sad.c * lib/target-supports.exp (check_effective_target_vect_usad_char): Add non-SVE aarch64 to supported list.

dwarf2out_finish performs: 1. save_macinfo_strings 2. hash table traverse of index_string 3. output_macinfo -> output_macinfo_op 4. output_indirect_strings -> hash table traverse of output_index_string find_slot_with_hash has if (insert == INSERT && m_size * 3 <= m_n_elements * 4) expand (); which may expand hash table even if no insertion is neeed and change hash table traverse order. When output_macinfo_op is called, all index strings have been added to hash table by save_macinfo_strings and we shouldn't expand index string hash table. Otherwise find_slot_with_hash will expand hash table when hash table has the right size and hash table traverse of output_index_string will have a different traverse order from index_string.

2018-12-17Add a loop versioning passRichard Sandiford39-12/+3204
This patch adds a pass that versions loops with variable index strides for the case in which the stride is 1. E.g.: for (int i = 0; i < n; ++i) x[i * stride] = ...; becomes: if (stepx == 1) for (int i = 0; i < n; ++i) x[i] = ...; else for (int i = 0; i < n; ++i) x[i * stride] = ...; This is useful for both vector code and scalar code, and in some cases can enable further optimisations like loop interchange or pattern recognition. The pass gives a 7.6% improvement on Cortex-A72 for 554.roms_r at -O3 and a 2.4% improvement for 465.tonto. I haven't found any SPEC tests that regress. Sizewise, there's a 10% increase in .text for both 554.roms_r and 465.tonto. That's obviously a lot, but in tonto's case it's because the whole program is written using assumed-shape arrays and pointers, so a large number of functions really do benefit from versioning. roms likewise makes heavy use of assumed-shape arrays, and that improvement in performance IMO justifies the code growth. The next biggest .text increase is 4.5% for 548.exchange2_r. I did see a small (0.4%) speed improvement there, but although both 3-iteration runs produced stable results, that might still be noise. There was a slightly larger (non-noise) improvement for a 256-bit SVE model. 481.wrf and 521.wrf_r .text grew by 2.8% and 2.5% respectively, but without any noticeable improvement in performance. No other test grew by more than 2%. Although the main SPEC beneficiaries are all Fortran tests, the benchmarks we use for SVE also include some C and C++ tests that benefit. Using -frepack-arrays gives the same benefits in many Fortran cases. The problem is that using that option inappropriately can force a full array copy for arguments that the function only reads once, and so it isn't really something we can turn on by default. The new pass is supposed to give most of the benefits of -frepack-arrays without the risk of unnecessary repacking. The patch therefore enables the pass by default at -O3. 2018-12-17 Richard Sandiford <richard.sandiford@arm.com> Ramana Radhakrishnan <ramana.radhakrishnan@arm.com> Kyrylo Tkachov <kyrylo.tkachov@arm.com> gcc/ * doc/invoke.texi (-fversion-loops-for-strides): Document (loop-versioning-group-size, loop-versioning-max-inner-insns) (loop-versioning-max-outer-insns): Document new --params. * Makefile.in (OBJS): Add gimple-loop-versioning.o. * common.opt (fversion-loops-for-strides): New option. * opts.c (default_options_table): Enable fversion-loops-for-strides at -O3. * params.def (PARAM_LOOP_VERSIONING_GROUP_SIZE) (PARAM_LOOP_VERSIONING_MAX_INNER_INSNS) (PARAM_LOOP_VERSIONING_MAX_OUTER_INSNS): New parameters. * passes.def: Add pass_loop_versioning. * timevar.def (TV_LOOP_VERSIONING): New time variable. * tree-ssa-propagate.h (substitute_and_fold_engine::substitute_and_fold): Add an optional block parameter. * tree-ssa-propagate.c (substitute_and_fold_engine::substitute_and_fold): Likewise.
