          Hardware: PC

I was trying to compile openssl on Windows, but stuck on chacha-x86.asm. Here
is a fragment of this file which throws error:

...
568     vpsubd  xmm0,xmm0,[64+eax]
569     vpshufd xmm6,xmm7,170
570     vpshufd xmm7,xmm7,255
571     vmovdqa [64+ebp],xmm0
572     vmovdqa [80+ebp],xmm1
573     vmovdqa [96+ebp],xmm2
574     vmovdqa [112+ebp],xmm3
575     vmovdqu xmm3,[16+edx]
576     vmovdqa [ebp-64],xmm4
577     vmovdqa [ebp-48],xmm5
578     vmovdqa [ebp-32],xmm6
579     vmovdqa [ebp-16],xmm7
560     vmovdqa xmm7,[32+eax]
561     lea     ebx,[128+esp]
562     vpshufd xmm0,xmm3,0
563     vpshufd xmm1,xmm3,85
...

And here is the error message:

chacha-x86.asm:571: error: operation size not specified
chacha-x86.asm:572: error: operation size not specified
chacha-x86.asm:573: error: operation size not specified
chacha-x86.asm:574: error: operation size not specified
chacha-x86.asm:576: error: operation size not specified
chacha-x86.asm:577: error: operation size not specified
...

This problem goes away when I switch back to version 2.13.02
