Hello, as discussed here in more detail: https://reviews.llvm.org/D81583 the introduction of the C++20 [[no_unique_address]] attribute exposes an ABI issue on platforms that require special handling for structs/classes that are "equivalent" to a single floating-point member (or in some cases, a "homogeneous" set of floating-point members). This is because we can now for the

I don't think anybody does constant folding on floating-point constants at the MachineIR level anyway ... have you seen this anywhere?

...is. If the backend wants to handle that by using the strictest rule that it sees in use anywhere in the function because pattern-matching is otherwise too error-prone, ok, that's its right; but the IR really should be per-instruction.

IIUC, splitting entities into constrained or non-constrained is a temporary solution, ideally they will merge into one entity. We could do it for some intrinsics now.

...ction, but the existing mechanism prevents that. My concern is that given LLVM's development model, if there is nothing in place to prevent constant folding and no consensus that it shouldn't be allowed then we should probably believe that someone will eventually do it. -Andy From: Ulrich Weigand [mailto:Ulrich.Weigand at de.ibm.com] Sent: Tuesday, January 09, 2018 9:59 AM To: Kaylor, Andrew <andrew.kaylor at intel.com>; kpn at neutralgood.org Cc: Hal Finkel <hfinkel at anl.gov>; Richard Smith <richard at metafoo.co.uk>; bob.huemmer at sas.com; bumblebritches57 at gmail.co...

...werPC. Should we do so as well? Note that mesa has in the meantime changed to do the auto-detection before setting up the JIT context, and I assume other JIT users have done so as well by now. For clang, this was never done automatically anyway.

...possible to generate those via multiclass instantiations so it might not be all that big a deal. The benefit would be that it allows the back-end the greatest freedom how to handle things (e.g. interactions with target-specific control registers).
