Perhaps I don't understand the SSE instructions correctly but AFAIK this should
work:
movups xmm0, [v1] // load v1 into reg0
addps xmm0, [v2] // add reg0 and v2
movups [vr], xmm0 // write reg0 to xmm0
The above code creates an Acess violation.
If I load v2 into a second register and add the two registers everything works
as expected.
movups xmm0, [v1] // load v1 into reg0
movups xmm1, [v2] // load v2 into reg1
addps xmm0, xmm1 // add reg0 and reg1
movups [vr], xmm0 // write reg0 to vr
v1, v2, vr are packed records of 4 singles
fpc version is 2.0.2
