Add save/restore xmm registers in x86 assembly code Went through the code and fixed it. Verified on Windows. Where possible, remove dependencies on xmm[67] Current code relies on pushing rbp to the stack to get 16 byte alignment. This broke when rbp wasn't pushed (vp8/encoder/x86/sad_sse3.asm). Work around this by using unaligned memory accesses. Revisit this and the offsets in vp8/encoder/x86/sad_sse3.asm in another change to SAVE_XMM. Change-Id: I5f940994d3ebfd977c3d68446cef20fd78b07877

Add save/restore xmm registers in x86 assembly code Went through the code and fixed it. Verified on Windows. Where possible, remove dependencies on xmm[67] Current code relies on pushing rbp to the stack to get 16 byte alignment. This broke when rbp wasn't pushed (vp8/encoder/x86/sad_sse3.asm). Work around this by using unaligned memory accesses. Revisit this and the offsets in vp8/encoder/x86/sad_sse3.asm in another change to SAVE_XMM. Change-Id: I5f940994d3ebfd977c3d68446cef20fd78b07877

nasm: match instruction length (movd/movq) to parameters nasm requires the instruction length (movd/movq) to match to its parameters. I find it more clear to really use 64bit instructions when we use 64bit registers in the assembly. Provide nasm compatibility. No binary change by this patch with yasm on {x86_64,i686}-fedora13-linux-gnu. Few longer opcodes with nasm on {x86_64,i686}-fedora13-linux-gnu have been checked as safe.
