From 1983f54daebc5b4ba0ebb3fbc6ec0abb083f8908 Mon Sep 17 00:00:00 2001 From: Richard Smith Date: Thu, 31 Jan 2013 22:19:12 +0000 Subject: Add -Wno-nested-anon-types to -pedantic builds of LLVM. This Clang warning catches uses of an extremely minor and widely-available C++ extension (which every C++ compiler I could find supports, but EDG and Clang reject in strict mode). The diagnosed code pattern looks like this: struct X { union { struct { int a; int b; } S; }; }; git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@174103 91177308-0d34-0410-b5e6-96231b3b80d8 --- autoconf/configure.ac | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) (limited to 'autoconf') diff --git a/autoconf/configure.ac b/autoconf/configure.ac index 21c3eeb..0a291c1 100644 --- a/autoconf/configure.ac +++ b/autoconf/configure.ac @@ -1264,6 +1264,7 @@ dnl Check optional compiler flags.
