One uses the JMPI instruction as in the original code but at least in my IronLake hardware it does not produce correct rendering of the GL_FILL face of the polygon. The other one uses IF/ELSE/ENDIF instructions and does produce correct results in IronLake. I don't know why only the latter works, maybe someone can look at the code and point out the problem. To test, run the sample program (line_aa) attached to this bug report like this: # Test solution with IF/END/ELSE ./line_aa # Test solution with JMPI INTEL_TRY_AA_JMPI=1 ./line_aa The correct result should show the front face of the triangle rendered in GL_LINE mode with antialiased lines and the back face rendered in GL_FILL mode with smooth interpolation of the red, green and blue vertices. I am particularly interested in having this tested in Gen < 5 since I don't have that hardware.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the QA Contact for the bug.</li> </ul> </body> </html>
