I can replicate the bug on Haswell by modifying commit 5a06ee7384934f to apply on Gen7, but without setting the SIMD4x2 bit in the header. It also has the bug if I leave it so that allocates register space for the header but doesn't actually send the header which means the registers are no longer overlapping. It seems like it's just the compiler going wrong somehow but if I compare the working one and the non-working one so far I haven't seen anything that looks wrong.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the QA Contact for the bug.</li> </ul> </body> </html>
