The amd-builtins branch in libclc looks like there's an erf implementation that can be ported over: <a href="https://llvm.org/svn/llvm-project/libclc/branches/amd-builtins/amd-builtins/math32/erfF.cl">https://llvm.org/svn/llvm-project/libclc/branches/amd-builtins/amd-builtins/math32/erfF.cl</a> The double implementation will need to be ported as well. Note that it looks like the AMD implementation of erf requires doubles if subnormals are NOT supported... If that's an issue for someone, we'll need a workaround for that.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the QA Contact for the bug.</li> <li>You are the assignee for the bug.</li> </ul> </body> </html>
