Author: Kristian Høgsberg Kristensen <k...@bitplanet.net> Date: Wed Sep 23 16:57:47 2015 -0700 i965: Respect stride and subreg_offset for ATTR registers When we assign hw regs to attributes, we don't incorporate the stride and subreg_offset from the fs_reg. It's rarely used, but the integer multiplication lowering uses unusual stride and subreg_offset combination breaks when one source is an attribute.
