From: Kugan Vivekanandarajah <kugan.vivekanandara...@linaro.org> In PR88834, IVOPT is not selecting the right addressing mode. Inorder to fix thix, we need to add support to add IV uses for IFN_MASK_LOAD_LANES and IFN_MASK_STORE_LANES. In addition, we also need to add IV candidate with scaled by the element or access size if that is useful. Richard Sandiford has provided some feedback in the PR and I tried to incoporate this in PATCH1.
PATCH 2 is the changes needed in aarch64 back in the testadjustments. Bootstrap and regression testing for the current version is ongoing. Thanks, Kugan Kugan Vivekanandarajah (2): Add support for IVOPT aarch64 back-end changes gcc/config/aarch64/aarch64.c | 2 +- gcc/testsuite/gcc.target/aarch64/pr88834.c | 15 ++++++ .../gcc.target/aarch64/sve/struct_vect_1.c | 8 +-- .../gcc.target/aarch64/sve/struct_vect_14.c | 8 +-- .../gcc.target/aarch64/sve/struct_vect_15.c | 8 +-- .../gcc.target/aarch64/sve/struct_vect_16.c | 8 +-- .../gcc.target/aarch64/sve/struct_vect_17.c | 8 +-- .../gcc.target/aarch64/sve/struct_vect_7.c | 8 +-- gcc/tree-ssa-loop-ivopts.c | 60 +++++++++++++++++++++- 9 files changed, 99 insertions(+), 26 deletions(-) create mode 100644 gcc/testsuite/gcc.target/aarch64/pr88834.c -- 2.7.4
