[PATCH] D71897: [X86] Adding fp128 support for strict fcmp

[Pengfei Wang via Phabricator via llvm-commits]

pengfei added a comment.

After a deeper investigation, I agreed with Craig that we should "expand the unsupported calls into multiple compares and control flow in IR". But I think we don't need libcalls. We can get sNaN, qNaN and compare results according to control flow and IRs. We only need to define a target dependent interface `TLI.raiseFPException` to handle exception respectively.
