*	[AMDGPU] Do not consider indirect acces through phi for wave limiter	Stanislav Mekhanoshin	2018-06-11	1	-0/+26
\| \| \| \| \| \| \| \| \| \| \|	Rational: if there is indirect access that is usually an issue because load is not ready by the use. However, if use is inside a loop and load is outside that is potentially an issue for a first iteration only. Differential Revision: https://reviews.llvm.org/D47740 llvm-svn: 334420
*	[AMDGPU] Add perf hints to functions	Stanislav Mekhanoshin	2018-05-25	1	-0/+85
	This is adoption of HSAIL perfhint pass. Two types of hints are produced: 1. Function is memory bound. 2. Kernel can use wave limiter. Currently these hints are used in the scheduler. If a function is suspected to be memory bound we allow occupancy to decrease to 4 waves in the course of scheduling. Differential Revision: https://reviews.llvm.org/D46992 llvm-svn: 333289
