From: Paul Berry Date: Wed, 31 Aug 2011 22:34:01 +0000 (-0700) Subject: i965: clip: Convert computations to ..._to_offset() for clarity. X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=2ef1fa6b3c8d52e059bf6ccf519c45604962b27c;p=mesa.git i965: clip: Convert computations to ..._to_offset() for clarity. This patch replaces some ad-hoc computations using ATTR_SIZE and the offset[] array to use the VUE map functions brw_vert_result_to_offset() and brw_vue_slot_to_offset().
