Subject: [PATCH] i386.c (ix86_preferred_simd_mode): Even for TARGET_AVX if not
TARGET_PREFER_AVX128 return 32-byte integer vectors.
* config/i386/i386.c (ix86_preferred_simd_mode): Even for TARGET_AVX
if not TARGET_PREFER_AVX128 return 32-byte integer vectors.
* gcc.target/i386/avx-cvt-2.c: Adjust for 32-byte integer vectors
being prefered even for -mavx.
* gcc.target/i386/avx-cvt-3.c: New test.
