Subject: i965/fs: add null_reg_df
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=c9ecd651e68c51379634980fbc964eb0b7590b5d;p=mesa.git

i965/fs: add null_reg_df

Probably not needed since we fix the dst type of comparisons
automatically, but for consistency with the rest of null_reg_*
functions.
