This is a heads-up regarding a change in the definition of the ARM neon
vld and vst intrinsics, mostly to solicit whether there are any
objections to this change.
The following patches:
change the interface of the vld, vldlane, and vst,
vstlane ARM neon intrinsics and associate an address space with the
pointer that these intrinsics take. This changed, for example,
<2 x i32> @llvm.arm.neon.vld1.v2i32(i8*, i32)
is changed to
<2 x i32> @llvm.arm.neon.vld1.v2i32.p0i8(i8*, i32)
This resolves an issue in the ARM Target where address spaces were only
partially taken into account during lowering of interleaved loads and
stores (see D12985 for further discussion).
As asked above, would there be any objection to making this change? Note
that the change does to alter the intrinsics exposed by clang, as before
only the address space 0 versions of the intrinsics are exposed.
