It's surprising that GLSL IR does unroll it. shader-db results BDW: total instructions in shared programs: 13037455 -> 13036947 (-0.00%) instructions in affected programs: 17982 -> 17474 (-2.83%) helped: 63 HURT: 25 total cycles in shared programs: 262217870 -> 262227990 (0.00%) cycles in affected programs: 2287046 -> 2297166 (0.44%) helped: 969 HURT: 844 total loops in shared programs: 2951 -> 2952 (0.03%) loops in affected programs: 0 -> 1 helped: 0 HURT: 1 LOST: 0 GAINED: 1 Reviewed-by: Jason Ekstrand <<a href="mailto:jason@jlekstrand.net">jason@jlekstrand.net</a>></pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> <li>You are the QA Contact for the bug.</li> </ul> </body> </html>
