From: Alexandre Oliva <aoliva@gcc.gnu.org> To: gcc-cvs@gcc.gnu.org Subject: [gcc(refs/users/aoliva/heads/testme)] adjust iteration count for ppc costmodel 76b Date: Sun, 28 Apr 2024 05:22:18 +0000 (GMT) [thread overview] Message-ID: <20240428052218.E4E373858D20@sourceware.org> (raw) https://gcc.gnu.org/g:ec1d688d102cd30572320e7224b55127182e2432 commit ec1d688d102cd30572320e7224b55127182e2432 Author: Kewen Lin <linkw@linux.ibm.com> Date: Sun Apr 28 01:43:51 2024 -0300 adjust iteration count for ppc costmodel 76b The original intention of this case is to expect not profitable for peeling. Tweak the loop bound to make this loop not profitable to be vectorized for !vect_no_align with peeling (both pwr7 and pwr6) and keep consistent. for gcc/testsuite/ChangeLog * gcc.dg/vect/costmodel/ppc/costmodel-vect-76b.c (N): Tweak.
