Daniel Stone	3d21fa56f5	libclc: Make all built-ins overloadable ... The SPIR spec states that all OpenCL built-in functions should be overloadable and mangled, to ensure consistency. Add the overload attribute to functions which were missing them: work dimensions, memory barriers and fences, and events.

Jan Vesely	999b1d9426	amdgcn: rewrite barrier() using fence and clang __builtin_amdgcn_s_barrier ... Specs require using fences when barrier() is invoked: "The barrier function will either flush any variables stored in local memory or queue a memory fence to ensure correct ordering of memory operations to local memory." and "The barrier function will queue a memory fence to ensure correct ordering of memory operations to global memory."

Matt Arsenault	a48e15c6cb	Split sources for amdgcn and r600 ... Most files remain in a common amdgpu directory. Also switches barriers to to use convergent, and use llvm.amdgcn.s.barrier. This now requires 3.9/trunk to build amdgcn. llvm-svn: 260777	2016-02-13 01:01:59 +00:00
