Thanks, that worked like a charm except for the following:
llvm generate:
call void @llvm.memcpy.p3i8.p1i8.i64(i8 addrspace(3)* align 1 bitcast
([512 x float] addrspace(3)* @a_scratchpad to i8 addrspace(3)*), i8
addrspace(1)* align 1 %0, i64 2048, i1 false)
And we expected:
call void @llvm.memcpy.p3i8.p1i8.i64(i8 addrspace(3)* bitcast ([512 x
float] addrspace(3)* [[SPM0]] to i8 addrspace(3)*), i8 addrspace(1)*
[[APTR]], i64 2048, i1 false)
Notice the presence of "align 1". I'm not sure which side is correct, isn't
it equivalent (that is, this is the natural ABI alignment of that type)?
Here is my datalayout:
target datalayout =
"e-m:e-i64:64-n8:16:32:64-S128-v16:16-v24:32-v32:32-v48:64-v96:128-v192:256-v256:256-v512:512-v1024:1024"
