commit 4e981cccad14ea3add39f92378da41d203814a60 Author: xuli <xu...@eswincomputing.com> Date: Mon May 20 01:56:47 2024 +0000 RISC-V: Enable vectorization for vect-early-break_124-pr114403.c Because "targetm.slow_unaligned_access" is set to true by default (aka -mtune=rocket) for RISC-V, it causes the __builtin_memcpy with 8 bytes failed to folded into int64 assignment during ccp1. So adding "-mtune=generic-ooo" to the RISC-V target can vectorize vect-early-break_124-pr114403.c. gcc/testsuite/ChangeLog: * gcc.dg/vect/vect-early-break_124-pr114403.c: Enable vectrization for RISC-V target.
