[CI-NOTIFY]: TCWG Bisect tcwg_bmk_tx1/gnu-release-aarch64-spec2k6-O2 - Build # 25 - Successful!
Successfully identified regression in *gcc* in CI configuration tcwg_bmk_gnu_tx1/gnu-release-aarch64-spec2k6-O2. So far, this commit has regressed CI configurations: - tcwg_bmk_gnu_tx1/gnu-release-aarch64-spec2k6-O2 Culprit: commit df7c22831f1e48dba49479c5960c1c180d8eab2c Author: Richard Sandiford Date: Thu Nov 14 15:12:58 2019 + Support vectorisation with mixed vector sizes After previous patches, it's now possible to make the vectoriser support multiple vector sizes in the same vector region, using related_vector_mode to pick the right vector mode for a given element mode. No port yet takes advantage of this, but I have a follow-on patch for AArch64. This patch also seemed like a good opportunity to add some more dump messages: one to make it clear which vector size/mode was being used when analysis passed or failed, and another to say when we've decided to skip a redundant vector size/mode. 2019-11-14 Richard Sandiford gcc/ * machmode.h (opt_machine_mode::operator==): New function. (opt_machine_mode::operator!=): Likewise. * tree-vectorizer.h (vec_info::vector_mode): Update comment. (get_related_vectype_for_scalar_type): Delete. (get_vectype_for_scalar_type_and_size): Declare. * tree-vect-slp.c (vect_slp_bb_region): Print dump messages to say whether analysis passed or failed, and with what vector modes. Use related_vector_mode to check whether trying a particular vector mode would be redundant with the autodetected mode, and print a dump message if we decide to skip it. * tree-vect-loop.c (vect_analyze_loop): Likewise. (vect_create_epilog_for_reduction): Use get_related_vectype_for_scalar_type instead of get_vectype_for_scalar_type_and_size. * tree-vect-stmts.c (get_vectype_for_scalar_type_and_size): Replace with... (get_related_vectype_for_scalar_type): ...this new function. Take a starting/"prevailing" vector mode rather than a vector size. Take an optional nunits argument, with the same meaning as for related_vector_mode. Use related_vector_mode when not auto-detecting a mode, falling back to mode_for_vector if no target mode exists. (get_vectype_for_scalar_type): Update accordingly. (get_same_sized_vectype): Likewise. * tree-vectorizer.c (get_vec_alignment_for_array_type): Likewise.

So far, this commit has regressed CI configurations: - tcwg_bmk_llvm_tx1/llvm-release-aarch64-spec2k6-O3_LTO Culprit: commit 669ddd1e9b1226432b003dbba05b99f8e992285b Author: Arthur Eubanks Date: Mon Jan 25 11:00:56 2021 -0800 Turn on the new pass manager by default This turns on the new pass manager by default for the optimization pipeline in Clang and ThinLTO in various LLD backends. This also makes uses of `opt -instcombine` use the new pass manager (unless specifically opted out). This does not affect the backend target-dependent codegen pipeline. If this causes regressions, you can opt out of the new pass manager either via the -DENABLE_EXPERIMENTAL_NEW_PASS_MANAGER=OFF CMake flag while building LLVM, or via various compiler flags, e.g. -flegacy-pass-manager for Clang or -Wl,--lto-legacy-pass-manager for ELF LLD. Please file bugs for any regressions. Major differences: * The inliner works slightly differently * -O1 does some amount of inlining * LCSSA and LoopSimplify are run before all loop passes * Loop unswitching is implemented slightly differently * A new SpeculateAroundPHIs pass is added to the pipeline https://lists.llvm.org/pipermail/llvm-dev/2021-January/148098.html Reviewed By: asbirlea, ychen, MaskRay, echristo Differential Revision: https://reviews.llvm.org/D95380 Results regressed to (for first_bad == 669ddd1e9b1226432b003dbba05b99f8e992285b) # reset_artifacts: -10 # build_abe binutils: -9 # build_abe stage1 -- --set gcc_override_configure=--disable-libsanitizer: -8 # build_abe linux: -7 # build_abe glibc: -6 # build_abe stage2 -- --set gcc_override_configure=--disable-libsanitizer: -5 # build_llvm true: -3 # true: 0 # benchmark -- -O3_LTO artifacts/build-669ddd1e9b1226432b003dbba05b99f8e992285b/results_id: 1 # 473.astar,astar_base.default regressed by 106 from (for last_good == b15cbaf5a03d0b32dbc32c37766e32ccf66e6c87) # reset_artifacts: -10 # build_abe binutils: -9 # build_abe stage1 -- --set gcc_override_configure=--disable-libsanitizer: -8 # build_abe linux: -7 # build_abe glibc: -6 # build_abe stage2 -- --set gcc_override_configure=--disable-libsanitizer: -5 # build_llvm true: -3 # true: 0 # benchmark -- -O3_LTO artifacts/build-b15cbaf5a03d0b32dbc32c37766e32ccf66e6c87/results_id: 1 Artifacts of last_good build: https://ci.linaro.org/job/tcwg_bmk_ci_llvm-bisect-tcwg_bmk_tx1-llvm-release-aarch64-spec2k6-O3_LTO/5/artifact/artifacts/build-b15cbaf5a03d0b32dbc32c37766e32ccf66e6c87/ Results ID of last_good: tx1_64/tcwg_bmk_llvm_tx1/bisect-llvm-release-aarch64-spec2k6-O3_LTO/3543 Artifacts of first_bad build: https://ci.linaro.org/job/tcwg_bmk_ci_llvm-bisect-tcwg_bmk_tx1-llvm-release-aarch64-spec2k6-O3_LTO/5/artifact/artifacts/build-669ddd1e9b1226432b003dbba05b99f8e992285b/ Results ID of first_bad: tx1_64/tcwg_bmk_llvm_tx1/bisect-llvm-release-aarch64-spec2k6-O3_LTO/3539 Build top page/logs: https://ci.linaro.org/job/tcwg_bmk_ci_llvm-bisect-tcwg_bmk_tx1-llvm-release-aarch64-spec2k6-O3_LTO/5/ Configuration details: Reproduce builds: mkdir investigate-llvm-669ddd1e9b1226432b003dbba05b99f8e992285b cd investigate-llvm-669ddd1e9b1226432b003dbba05b99f8e992285b git clone https://git.linaro.org/toolchain/jenkins-scripts mkdir -p artifacts/manifests curl -o artifacts/manifests/build-baseline.sh https://ci.linaro.org/job/tcwg_bmk_ci_llvm-bisect-tcwg_bmk_tx1-llvm-release-aarch64-spec2k6-O3_LTO/5/artifact/artifacts/manifests/build-baseline.sh --fail curl -o artifacts/manifests/build-parameters.sh https://ci.linaro.org/job/tcwg_bmk_ci_llvm-bisect-tcwg_bmk_tx1-llvm-release-aarch64-spec2k6-O3_LTO/5/artifact/artifacts/manifests/build-parameters.sh --fail curl -o artifacts/test.sh https://ci.linaro.org/job/tcwg_bmk_ci_llvm-bisect-tcwg_bmk_tx1-llvm-release-aarch64-spec2k6-O3_LTO/5/artifact/artifacts/test.sh --fail chmod +x artifacts/test.sh # Reproduce the baseline build (build all pre-requisites) ./jenkins-scripts/tcwg_bmk-build.sh @@ artifacts/manifests/build-baseline.sh # Save baseline build state (which is then restored in artifacts/test.sh) mkdir -p ./bisect rsync -a --del --delete-excluded --exclude /bisect/ --exclude /artifacts/ --exclude /llvm/ ./ ./bisect/baseline/ cd llvm # Reproduce first_bad build git checkout --detach 669ddd1e9b1226432b003dbba05b99f8e992285b ../artifacts/test.sh # Reproduce last_good build git checkout --detach b15cbaf5a03d0b32dbc32c37766e32ccf66e6c87 ../artifacts/test.sh cd ..
