From: Matt Turner Date: Thu, 15 May 2014 23:56:13 +0000 (-0700) Subject: i965: Pass in start_offset to brw_compact_instructions(). X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=9976294e867785ea480f52178a3d3dc67ac72d32;p=mesa.git i965: Pass in start_offset to brw_compact_instructions(). Let's us avoid recompacting the SIMD8 instructions when we compact the SIMD16 program.
