This would allow vec4_cmod_propagation to optimize out several movs involving null registers. v2: added support to track each flag channel independently at vec4 live_variables, as v1 assumed that it was already doing it, as pointed by Francisco Jerez v3: general cleaningn after Matt Turner's review Reviewed-by: Matt Turner <<a href="mailto:mattst88@gmail.com">mattst88@gmail.com</a>> That was also the last one to be tested. Removing this commit remove the regressions. Will investigate a little this one.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the QA Contact for the bug.</li> </ul> </body> </html>
