From: Alexandre Oliva <aoliva@gcc.gnu.org> To: gcc-cvs@gcc.gnu.org Subject: [gcc(refs/users/aoliva/heads/testme)] disable ldist for test, to restore vectorizing-candidate loop Date: Thu, 30 Mar 2023 14:06:45 +0000 (GMT) [thread overview] Message-ID: <20230330140645.E8FFB3858288@sourceware.org> (raw) https://gcc.gnu.org/g:aa5af019f009dd9b745fc766b76d3962bf865674 commit aa5af019f009dd9b745fc766b76d3962bf865674 Author: Alexandre Oliva <oliva@adacore.com> Date: Thu Mar 30 05:06:38 2023 -0300 disable ldist for test, to restore vectorizing-candidate loop The loop we're supposed to try to vectorize in gcc.dg/vect/costmodel/ppc/costmodel-vect-31a.c is turned into a memset before the vectorizer runs. Various other tests in this set have already run into this, and the solution has been to disable this loop distribution transformation, enabled at -O2, so that the vectorizer gets a chance to transform the loop and, in this testcase, fail to do so. for gcc/testsuite/ChangeLog * gcc.dg/vect/costmodel/ppc/costmodel-vect-31a.c: Disable ldist.
