Subject: i965/sf: Drop unnecessary push/pop in copy_z_inv_w.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=471bff4c626d6a378e56e21e0c7e5e54ac523b23;p=mesa.git

i965/sf: Drop unnecessary push/pop in copy_z_inv_w.

brw_MOV doesn't alter the default instruction state, so this does
nothing.
