Justin Holewinski	3d140fcfd1	[NVPTX] Add NVPTXLowerStructArgs pass ... This works around the limitation that PTX does not allow .param space loads/stores with arbitrary pointers. If a function has a by-val struct ptr arg, say foo(%struct.x *byval %d), then add the following instructions to the first basic block : %temp = alloca %struct.x, align 8 %tt1 = bitcast %struct.x * %d to i8 * %tt2 = llvm.nvvm.cvt.gen.to.param %tt2 %tempd = bitcast i8 addrspace(101) * to %struct.x addrspace(101) * %tv = load %struct.x addrspace(101) * %tempd store %struct.x %tv, %struct.x * %temp, align 8 The above code allocates some space in the stack and copies the incoming struct from param space to local space. Then replace all occurences of %d by %temp. Fixes PR21465. llvm-svn: 221377	2014-11-05 18:19:30 +00:00
