Subject: i965/fs: Assert that the number of color targets is one when dual-source blend is... 
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=6df215d97eab6e18a8c70c9966014f6ab2bbc20a;p=mesa.git

i965/fs: Assert that the number of color targets is one when dual-source blend is enabled.

Requested by Anuj during review of
4a87e4ade778e56d43333c65a58752b15a00ce69, adding as follow-up since it
led to assertion failures due to various GLSL bugs that should be
fixed now.
