Subject: i965/fs: Add (sub)reg_offset asserts to brw_reg_from_fs_reg.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=437e65f9d93f8df0e6aaf1bcaf74c6a211498db8;p=mesa.git

i965/fs: Add (sub)reg_offset asserts to brw_reg_from_fs_reg.

These are completely ignored by the conversion to brw_reg, so they
better be zero.
