The usual approach to setting the NEON options is to use dg-add-options arm_neon. But in the lto tests we don't have that framework, we can only set them explicitly with dg-lto-options. The solution is to remove the explicit -mfloat-abi=softfp and instead add an effective target check for arm_neon_ok_no_float_abi that makes sure we only run this test if -mfpu=neon is enough to get NEON without any -mfloat-abi options. In fact, this is what the comment above check_effective_target_arm_neon_ok_no_float_abi_nocache recommends for lto tests. That way on my hardfloat toolchain the test doesn't try to link the softfp binary against a hard-float runtime/test glue and all is good. I've tested that the test is appropriately skipped when testing a --with-float=soft toolchain. * gcc.dg/lto/20110201-1_0.c: Remove explicit -mfloat-abi=softfp option. Add arm_neon_ok_no_float_abi check.
