[Mesa-dev] [PATCH 23/59] intel/compiler: Extended Math is limited to SIMD8 on half-float

2018-12-03 Thread Iago Toral Quiroga
From the Skylake PRM, Extended Math Function: "The execution size must be no more than 8 when half-floats are used in source or destination operand." Earlier generations do not support Extended Math with half-float. --- src/intel/compiler/brw_fs.cpp | 30 +++--- 1
