[PATCH] ARM/NEON: vld1q_dup_s64 builtin

[Christophe Lyon]

Hello,

On ARM+Neon, the expansion of vld1q_dup_s64() and vld1q_dup_u64() builtins 
currently fails to load the second vector element.

Here is a small patch to address this problem:

2012-05-07  Christophe Lyon <christophe.l...@st.com>

    * gcc/config/arm/neon.md (neon_vld1_dup): Fix vld1q_dup_s64.

OK?

Thanks,
