...? (way before the assembler jumps in) The annotation belongs to the instruction and other manipulations that are performed later (like reordering of instructions) should keep the annotation (iff the instruction itself is kept).

...aliased pointer over the non-aliased one because we don't want the no-aliasing information to creep outwards from the inlined callsite. I'll put together a patch in the coming days and add y'all as reviewers so you get visibility. Cheers, -Neil.

Hi, is there a convenient way to associate/add a comment to a MachineInstruction, so that in the produced assembly file, the comment is added next to the instruction ? Greetings, Jeroen Dobbelaere

Johannes, Thanks, I have been following along some of the thread(s) and the phab reviews. The scope of this work is more encompassing than our current needs and I've looked at trying to carve a piece out. It's not clear to me what purpose the llvm.noalias intrinsic serves right now. Also, if a mem instruction has !noalias metadata, then it should not be aliased, but I must be missing

...if the operand was not promoted. So it fails on the operands of the 'store' that were already legal (i64). What would be the recommended way to fix this ?

At a high level, EarlyCSE should be intersecting the metadata of instructions that it combines. If it doesn't, and also doesn't drop the metadata, that seems like a bug, regardless of anything else.
