[Mesa-dev] [RFC PATCH 5/5] i965: Skip execution size adjustment for instructions of width 4

2015-12-09 Thread Iago Toral Quiroga
This code in brw_set_dest adjusts the execution size of any instruction with a dst.width < 8. However, we don't want to do this with instructions operating on doubles, since these will have a width of 4, but still need an execution size of 8 (for SIMD8). Unfortunately, we can't just check the size
