on bug 65873
from Tom Stellard
The SI backend needs to be fixed so it can handle zext i64 loads, but there is
also a bug in libclc. The vload implementation assumes pointer types are
32-bit:
define <2 x i32> @__clc_vload2_impl_i32__global(i32 %offset, i32 addrspace(1)*
nocapture %addr) nounwind readonly alwaysinline {
%1 = ptrtoint i32 addrspace(1)* %addr to i32
%2 = add i32 %1, %offset
%3 = inttoptr i32 %2 to <2 x i32> addrspace(1)*
%4 = load <2 x i32> addrspace(1)* %3, align 4, !tbaa !3
ret <2 x i32> %4
}
Pointers on SI are 64-bit. This ptrtoint, add, inttoptr sequence should be
replaced with a getelementptr and a bitcast.
