| <h2>Description</h2> |
| <p> |
| 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. |
