commit r16-4904-g2be505ace7e5e29a29ab53025762cf1a100a6d76 Author: Lulu Cheng <[email protected]> Date: Thu Mar 6 16:28:08 2025 +0800 LoongArch: Remove the "-mlasx" compilation option from the test cases. Because LoongArch previously lacked support for 128-bit vectors (vec_widen_{add/sub/mult}_{hi/lo}), the following test cases needed to be enabled for 256-bit vectors to pass. Now that 128-bit support has been added, "-mlasx" has been removed. gcc/testsuite/ChangeLog: * gcc.dg/vect/slp-widen-mult-half.c: Remove '-mlasx'. * gcc.dg/vect/tree-vect.h: Check whether the runtime environment supports LSX instructions. * gcc.dg/vect/vect-widen-mult-const-s16.c: Dito. * gcc.dg/vect/vect-widen-mult-const-u16.c: Dito. * gcc.dg/vect/vect-widen-mult-half-u8.c: Dito. * gcc.dg/vect/vect-widen-mult-half.c: Dito. * gcc.dg/vect/vect-widen-mult-u16.c: Dito. * gcc.dg/vect/vect-widen-mult-u8-s16-s32.c: Dito. * gcc.dg/vect/vect-widen-mult-u8-u32.c: Dito. * gcc.dg/vect/vect-widen-mult-u8.c: Dito.
