https://community.intel.com/t5/Intel-ISA-Extensions/Problem-with-SSE2-code/m-p/867266#M2273 Hi!<BR /><BR />I have a problem with a SSE2 code, that I can`t resolve. The piece of code is this:<BR /><BR /><BR />asm("movupd xmm1, [xp]");xp+=2;<BR />asm("movupd xmm0 , [yp]");yp+=2; <BR /><BR />asm("addpd xmm1, xmm0\n"); <BR /><BR />asm("movupd [yp], xmm1\n");<BR /><BR /><BR />"yp" at this moment becomes null so I think this is "addpd"s fault because if "addpd" instruction is commented, yp keeps the reference. <BR />Somebody knows about this? I`ve been with this for several hours and I can`t see it.<BR /><BR />Thanks in advance!!! :) Fri, 18 Sep 2009 18:06:32 GMT ijjys 2009-09-18T18:06:32Z https://community.intel.com/t5/Intel-ISA-Extensions/Problem-with-SSE2-code/m-p/867266#M2273 Hi!<BR /><BR />I have a problem with a SSE2 code, that I can`t resolve.
