[LLVMdev] Address space extension
...lf, and is something we should have in the metadata.
I don’t know if CUDA has aliasing address spaces, but that would also be useful to consider. Something simple like this might work. Note i’m using the examples from the clang discussion, that is "1 = opencl/cuda global, 2 = opencl_local/cuda_shared, 3 = opencl/cuda constant"
!address_spaces = !{!0, !1, !2, !3}
; Address space tuple. { address space number, parent address space, additional properties }
!0 = metadata !{ i32 0, !{}, !{} }
!1 = metadata !{ i32 1, !0, !{} }
!2 = metadata !{ i32 2, !0, !{} }
!3 = metadata !{ i32 3, !0, !...

You are assuming that the target device has different physical address
spaces (like, PTX or R600 or TCE). What for those one with an unique
address space (e.g. X86, ARM) where all opencl/cuda address spaces are
mapped (correctly) to the target address space 0?...

[LLVMdev] Address space extension
Hello to everybody,
I would like to start a discussion about a possible extension of address
space concept in LLVM.
The idea was born starting from this discussion in the clang mailing
list (first msg:
http://lists.cs.uiuc.edu/pipermail/cfe-commits/Week-of-Mon-20130715/084011.html
- interesting point:
