From 5ca575182338a2670f3e7d636c48a2e2ef2d32dc Mon Sep 17 00:00:00 2001 From: eric fang Date: Mon, 20 Apr 2020 08:42:01 +0000 Subject: runtime: fix TestCallersNilPointerPanic The expected result of TestCallersNilPointerPanic has changed in GoLLVM. This CL makes some elements of the expected result optional so that this test passes in both gccgo and GoLLVM.
