Many tests became unsupported on aarch64 when -mcpu=unset was added to several arm_* effective targets, because this flag is only supported on arm.
Since these effective targets are used on arm and aarch64, the patch adds -mcpu=unset on arm only, and restores "" on aarch64. This re-enables lots of tests: advsimd-intrinsics/vqrdmlah fp16 tests dotprod tests i8mm tests aarch64/simd/vmmla.c bf16 tests gcc.dg/vect/complex tests With this change, a few more failures appear, but should be fixed separately: FAIL: gcc.dg/vect/complex/fast-math-complex-mls-double.c -flto -ffat-lto-objects scan-tree-dump vect "Found COMPLEX_ADD_ROT270" FAIL: gcc.dg/vect/complex/fast-math-complex-mls-double.c scan-tree-dump vect "Found COMPLEX_ADD_ROT270" FAIL: gcc.dg/vect/complex/fast-math-complex-mls-float.c -flto -ffat-lto-objects scan-tree-dump vect "Found COMPLEX_ADD_ROT270" FAIL: gcc.dg/vect/complex/fast-math-complex-mls-float.c scan-tree-dump vect "Found COMPLEX_ADD_ROT270" FAIL: gcc.dg/vect/complex/fast-math-complex-mls-half-float.c -flto -ffat-lto-objects scan-tree-dump vect "Found COMPLEX_ADD_ROT270" FAIL: gcc.dg/vect/complex/fast-math-complex-mls-half-float.c scan-tree-dump vect "Found COMPLEX_ADD_ROT270" gcc/testsuite/ChangeLog * lib/target-supports.exp (check_effective_target_arm_v8_1a_neon_ok_nocache): Use -mcpu=unset on arm only.
