Subject: i965: Fix GPU hangs when INTEL_DEBUG=no16 is set.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=70691f0c283ec4e03523f3a4690d9b897b36872e;p=mesa.git

i965: Fix GPU hangs when INTEL_DEBUG=no16 is set.

The replicated data clear shader needs to be SIMD16, or else the GPU
will hang.  So, compile it even if INTEL_DEBUG=no16 is set.
