--- Comment #7 from Matthias Kretz <kretz at kde dot org> 2012-09-26 10:52:38 UTC --- Thanks for the quick response! You guys are cool! :) The pattern here is for calculation with extended precision: xh = x & mask; xl = x - xh; yh = y & mask yl = y - yh; /* x * y + small = */ xh * yh + ((xh * yl + xl * yh) + (xl * yl + small)); Other than that, yes there's a lot of ANDPS is SSE code, just this pattern which gets miscompiled is not very common.
