From ff7900d5def4f645a6675d99ad39a38d8a468a63 Mon Sep 17 00:00:00 2001 From: Gui Andrade Date: Wed, 8 Jul 2020 17:22:48 +0000 Subject: [LLVM] Accept `noundef` attribute in function definitions/calls The `noundef` attribute indicates an argument or return value which may never have an undef value representation. This patch allows LLVM to parse the attribute.
