Subject: i965: Also consider HALTs a potential block end.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=7baf9198b201666fc0f20fe407d7b46ee0ca7ef5;p=mesa.git

i965: Also consider HALTs a potential block end.

The final halt of the fragment shader turns off the remaining channels,
then jumps such that everything is turned back on.  So, we can have our
last ENDIF of the shader point at that directly.
