2019-10-31[vect]Make vect-epilogues-nomask=1 defaultAndre Vieira1-1/+1
This patch turns epilogue vectorization on by default for all targets. The following test strategy was chosen for this: 1) Disable epilogue vectorization for all tests that failed due to scan-tree-dump failures for aarch64, arm and x86_64 inside: - gcc.dg/vect - gcc.target/i386 - gcc.target/aarch6 - gfortran.dg/vect 2) Add the Bugzilla's reported testcase but xfail the scan for "EPILOGUE VECTORIZED" for arm*-*-* as that target does not vectorize the epilogue. gcc/ChangeLog: 2019-10-31 Andre Vieira <andre.simoesdiasvieira@arm.com> * params.def (PARAM_VECT_EPILOGUES_NOMASK): Enable by default. gcc/testsuite/ChangeLog: 2019-10-31 Andre Vieira <andre.simoesdiasvieira@arm.com> * gcc.dg/vect/vect-epilogues.c: New test. * gcc.dg/vect/fast-math-vect-call-1.c: Disable for epilogue vectorization. * gcc.dg/vect/no-fast-math-vect16.c: Likewise. * gcc.dg/vect/no-scevccp-noreassoc-slp-reduc-7.c: Likewise. * gcc.dg/vect/no-scevccp-vect-iv-3.c: Likewise. * gcc.dg/vect/no-section-anchors-vect-31.c: Likewise. * gcc.dg/vect/no-section-anchors-vect-64.c: Likewise. * gcc.dg/vect/no-section-anchors-vect-66.c: Likewise. * gcc.dg/vect/no-section-anchors-vect-68.c: Likewise. * gcc.dg/vect/no-vfa-vect-dv-2.c: Likewise. * gcc.dg/vect/pr33804.c: Likewise. * gcc.dg/vect/pr53773.c: Likewise. * gcc.dg/vect/pr65947-1.c: Likewise. * gcc.dg/vect/pr65947-13.c: Likewise. * gcc.dg/vect/pr65947-14.c: Likewise. * gcc.dg/vect/pr65947-4.c: Likewise. * gcc.dg/vect/pr80631-1.c: Likewise. * gcc.dg/vect/pr80631-2.c: Likewise. * gcc.dg/vect/slp-23.c: Likewise. * gcc.dg/vect/slp-25.c: Likewise. * gcc.dg/vect/slp-reduc-2.c: Likewise. * gcc.dg/vect/slp-reduc-5.c: Likewise. * gcc.dg/vect/slp-reduc-6.c: Likewise. * gcc.dg/vect/slp-reduc-sad-2.c: Likewise. * gcc.dg/vect/slp-widen-mult-half.c: Likewise. * gcc.dg/vect/trapv-vect-reduc-4.c: Likewise. * gcc.dg/vect/vect-103.c: Likewise. * gcc.dg/vect/vect-109.c: Likewise. * gcc.dg/vect/vect-119.c: Likewise. * gcc.dg/vect/vect-24.c: Likewise. * gcc.dg/vect/vect-26.c: Likewise. * gcc.dg/vect/vect-27.c: Likewise. * gcc.dg/vect/vect-29.c: Likewise. * gcc.dg/vect/vect-42.c: Likewise. * gcc.dg/vect/vect-44.c: Likewise. * gcc.dg/vect/vect-48.c: Likewise. * gcc.dg/vect/vect-50.c: Likewise. * gcc.dg/vect/vect-52.c: Likewise. * gcc.dg/vect/vect-54.c: Likewise. * gcc.dg/vect/vect-56.c: Likewise. * gcc.dg/vect/vect-58.c: Likewise. * gcc.dg/vect/vect-60.c: Likewise. * gcc.dg/vect/vect-72.c: Likewise. * gcc.dg/vect/vect-75-big-array.c: Likewise. * gcc.dg/vect/vect-75.c: Likewise. * gcc.dg/vect/vect-77-alignchecks.c: Likewise. * gcc.dg/vect/vect-77-global.c: Likewise. * gcc.dg/vect/vect-78-alignchecks.c: Likewise. * gcc.dg/vect/vect-78-global.c: Likewise. * gcc.dg/vect/vect-89-big-array.c: Likewise. * gcc.dg/vect/vect-89.c: Likewise. * gcc.dg/vect/vect-91.c: Likewise. * gcc.dg/vect/vect-92.c: Likewise. * gcc.dg/vect/vect-96.c: Likewise. * gcc.dg/vect/vect-cond-reduc-3.c: Likewise. * gcc.dg/vect/vect-cond-reduc-4.c: Likewise. * gcc.dg/vect/vect-live-1.c: Likewise. * gcc.dg/vect/vect-live-2.c: Likewise. * gcc.dg/vect/vect-live-3.c: Likewise. * gcc.dg/vect/vect-live-4.c: Likewise. * gcc.dg/vect/vect-live-slp-1.c: Likewise. * gcc.dg/vect/vect-live-slp-2.c: Likewise. * gcc.dg/vect/vect-live-slp-3.c: Likewise. * gcc.dg/vect/vect-multitypes-3.c: Likewise. * gcc.dg/vect/vect-multitypes-4.c: Likewise. * gcc.dg/vect/vect-multitypes-6.c: Likewise. * gcc.dg/vect/vect-peel-1-epilogue.c: Likewise.

2018-12-17Add a loop versioning passRichard Sandiford1-0/+13
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.

2018-10-01Allow setting of stack-clash via configure options.Tamar Christina1-2/+3
This patch defines a configure option to allow the setting of the default guard size via configure flags when building the target. The new flag is: * --with-stack-clash-protection-guard-size=<num> The patch defines a new macro DEFAULT_STK_CLASH_GUARD_SIZE which targets need to use explicitly is they want to support this configure flag and values that users may have set. gcc/ PR target/86486 * configure.ac: Add stack-clash-protection-guard-size. * doc/install.texi: Document it. * config.in (DEFAULT_STK_CLASH_GUARD_SIZE): New. * params.def: Update comment for guard-size.

2018-07-133nd Patch for PR78009Qing Zhao1-0/+4
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=78809 Inline strcmp with small constant strings The design doc for PR78809 is at: https://www.mail-archive.com/gcc@gcc.gnu.org/msg83822.html this patch is for the third part of change of PR78809. C. for strcmp (s1, s2), strncmp (s1, s2, n), and memcmp (s1, s2, n) if the result is NOT used to do simple equality test against zero, one of "s1" or "s2" is a small constant string, n is a constant, and the Min value of the length of the constant string and "n" is smaller than a predefined threshold T, inline the call by a byte-to-byte comparision sequence to avoid calling overhead. adding test case strcmpopt_5.c into gcc.dg for part C of PR78809. adding test case strcmpopt_6.c into gcc.dg to test the following case: When the specified length exceeds one of the arguments of the call to memcmp, the call to memcmp should NOT be inlined.

2018-05-23[Patch 02/02] Introduce prefetch-dynamic-strides optionLuis Machado1-0/+9
The following patch adds an option to control software prefetching of memory references with non-constant/unknown strides. Currently we prefetch these references if the pass thinks there is benefit to doing so. But, since this is all based on heuristics, it's not always the case that we end up with better performance. For Falkor there is also the problem of conflicts with the hardware prefetcher, so we need to be more conservative in terms of what we issue software prefetch hints for. This also aligns GCC with what LLVM does for Falkor. Similarly to the previous patch, the defaults guarantee no change in behavior for other targets and architectures. gcc/ChangeLog: 2018-05-23 Luis Machado <luis.machado@linaro.org> * config/aarch64/aarch64-protos.h (cpu_prefetch_tune) <prefetch_dynamic_strides>: New const bool field. * config/aarch64/aarch64.c (generic_prefetch_tune): Update to include prefetch_dynamic_strides.

2018-05-23[Patch 01/02] Introduce prefetch-minimum stride optionLuis Machado1-0/+9
This patch adds a new option to control the minimum stride, for a memory reference, after which the loop prefetch pass may issue software prefetch hints for. There are two motivations: * Make the pass less aggressive, only issuing prefetch hints for bigger strides that are more likely to benefit from prefetching. I've noticed a case in cpu2017 where we were issuing thousands of hints, for example. * For processors that have a hardware prefetcher, like Falkor, it allows the loop prefetch pass to defer prefetching of smaller (less than the threshold) strides to the hardware prefetcher instead. This prevents conflicts between the software prefetcher and the hardware prefetcher. I've noticed considerable reduction in the number of prefetch hints and slightly positive performance numbers. This aligns GCC and LLVM in terms of prefetch behavior for Falkor. The default settings should guarantee no changes for existing targets. Those are free to tweak the settings as necessary. gcc/ChangeLog: 2018-05-23 Luis Machado <luis.machado@linaro.org> * config/aarch64/aarch64-protos.h (cpu_prefetch_tune) <minimum_stride>: New const int field. * config/aarch64/aarch64.c (generic_prefetch_tune): Update to include minimum_stride field defaulting to -1.
