            Additions to section 5.8.1 –Creating Program Objects:
        </p>
        <p>
            This extension adds the device property
            <code class="constant">CL_DEVICE_SPIR_VERSIONS</code> to Table 4.3 (see 
            <a class="citerefentry" href="clGetDeviceInfo.html"><span class="citerefentry"><span class="refentrytitle">clGetDeviceInfo</span></span></a>).
        </p>
        <p>
            Additions to section 5.8.1 –Creating Program Objects:
        </p>
        <p>
            <a class="citerefentry" href="clCreateProgramWithBinary.html"><span class="citerefentry"><span class="refentrytitle">clCreateProgramWithBinary</span></span></a> 
            can be used to load a SPIR binary. Once a program object has 
            been created from a SPIR binary, 
            <a class="citerefentry" href="clBuildProgram.html"><span class="citerefentry"><span class="refentrytitle">clBuildProgram</span></span></a>  
            can be called to build a program executable 
            or <a class="citerefentry" href="clCompileProgram.html"><span class="citerefentry"><span class="refentrytitle">clCompileProgram</span></span></a> 
            can be called to compile the SPIR binary.
        </p>
        <p>
            Modify the <code class="constant">CL_PROGRAM_BINARY_TYPE</code> entry in table 5.14 
            (see <a class="citerefentry" href="clGetProgramBuildInfo.html"><span class="citerefentry"><span class="refentrytitle">clGetProgramBuildInfo</span></span></a>)
            to add a potential value <code class="constant">CL_PROGRAM_BINARY_TYPE_INTERMEDIATE</code>.
        </p>
        <p>
            Additions to section 5.8.4 –Compiler Options.:
        </p>
        <p>
            The compile option <code class="code">-x spir</code> must be specified 
            to indicate that the binary is in SPIR format, and
            the compile option <code class="code">-spir-std</code> must be used 
            to specify the version of the SPIR specification that 
            describes the format and meaning of the binary. For 
            example, if the binary is as described in 
            SPIR version 1.2, then <code class="code">-spir-std=1.2</code> must 
            be specified. Failing to specify these compile options 
            may result in implementation defined behavior.
