From de553d906b4a205d811a9e1651f14212ec284e29 Mon Sep 17 00:00:00 2001 From: Jerome Glisse Date: Fri, 23 Jul 2010 17:32:32 -0400 Subject: r600g: drop compiler stuff and switch over dumb tgsi assembler Writing a compiler is time consuming and error prone in order to allow r600g to further progress in the meantime i wrote a simple tgsi assembler, it does stupid thing but i would rather keep the code simple than having people trying to optimize code it does.
