Details

this was spotted in a trace: 301 fld 299(10) 00A86A9C movsd xmm0,-16(ebx) ebx(10) 00A86AA1 movq xmm1,-16(ebx) ebx(10) xmm0(301) 00A86AA6 movq -16(ebp),xmm1 ebx(10) xmm0(301) the code could have been simpler: movq xmm0,-16(ebx) movq -16(ebp),xmm0 movsd and movq do the same thing in this situation. the change eliminates an extra load.

almost certianly a dupe of 520714, which is more comprehensive.
