Subject: r300g: only set clip_halfz for chips with HW TCL
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=3fc499a1dd2a98fdd9aa9c457a5607531c6696e1;p=mesa.git

r300g: only set clip_halfz for chips with HW TCL

I forgot that we cannot emit vertex shader state on a chip without VS.
In such a case, clip_halfz is handled by the Draw module.
