[Mesa-dev] [PATCH 03/41] i965/fs: Add a concept of a width to fs_reg

2014-09-20 Thread Jason Ekstrand
Every register in i965 assembly implicitly has a concept of a "width". Usually, this is derived from the execution size of the instruction. However, when writing a compiler it turns out that it is frequently a useful to have the width explicitly in the register and derive the execution size of the
