Sanjay Patel e53dbeb2ad [X86, AVX] improve insertion into zero element of 256-bit vector ... This patch allows AVX blend instructions to handle insertion into the low element of a 256-bit vector for the appropriate data types. For f32, instead of: vblendps $1, %xmm1, %xmm0, %xmm1 ## xmm1 = xmm1[0],xmm0[1,2,3] vblendps $15, %ymm1, %ymm0, %ymm0 ## ymm0 = ymm1[0,1,2,3],ymm0[4,5,6,7] we get: vblendps $1, %ymm1, %ymm0, %ymm0 ## ymm0 = ymm1[0],ymm0[1,2,3,4,5,6,7] For f64, instead of: vmovsd %xmm1, %xmm0, %xmm1 ## xmm1 = xmm1[0],xmm0[1] vblendpd $3, %ymm1, %ymm0, %ymm0 ## ymm0 = ymm1[0,1],ymm0[2,3] we get: vblendpd $1, %ymm1, %ymm0, %ymm0 ## ymm0 = ymm1[0],ymm0[1,2,3] For the hardware-neglected integer data types, I left a TODO comment in the code and added regression tests for a follow-on patch.
