Calculates the maximum of the sources.
max vDest, vSrc0, vSrc1
The following code fragment shows the operations performed by the max instruction to write a result to the destination.
SetDestReg(); SetSrcReg(0); SetSrcReg(1); m_TmpReg.x=(m_Source[0].x >= m_Source[1].x) ? m_Source[0].x : m_Source[1].x; m_TmpReg.y=(m_Source[0].y >= m_Source[1].y) ? m_Source[0].y : m_Source[1].y; m_TmpReg.z=(m_Source[0].z >= m_Source[1].z) ? m_Source[0].z : m_Source[1].z; m_TmpReg.w=(m_Source[0].w >= m_Source[1].w) ? m_Source[0].w : m_Source[1].w; WriteResult();
The following example illustrates how the max instruction might be used.
max r2, r3, r4
