--- Comment #18 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The releases/gcc-8 branch has been updated by Bin Cheng <am...@gcc.gnu.org>: https://gcc.gnu.org/g:0a7a2b7c64a77218e504e8390af29cfa5f79a242 commit r8-10320-g0a7a2b7c64a77218e504e8390af29cfa5f79a242 Author: Bin Cheng <bin.ch...@linux.alibaba.com> Date: Sat Jun 20 16:56:21 2020 +0800 Add missing unit dependence vector in data dependence analysis Current data dependence analysis misses unit distant vector if DRs in DDR have the same invariant access functions. This adds the vector as the constant access function case. Also fix typo in testcase. Backport from master commit: 287552950d56be47adb6b6bf2eae2d612233eaec and f6e1a4cd83190746b6544917f7526fa480ca5f18 2020-06-20 Bin Cheng <bin.ch...@linux.alibaba.com> gcc/ PR tree-optimization/94969 * tree-data-ref.c (constant_access_functions): Rename to...
