From 5d48424a30960cce0b5b178a284eedab1c16c79c Mon Sep 17 00:00:00 2001 From: Alex Lorenz Date: Wed, 26 Jul 2017 12:20:57 +0000 Subject: Recommit r308327 2nd time: Add a warning for missing '#pragma pack (pop)' and suspicious uses of '#pragma pack' in included files The first recommit (r308441) caused a "non-default #pragma pack value might change the alignment of struct or union members in the included file" warning in LLVM itself. This recommit tweaks the added warning to avoid warnings for #includes that don't have any records that are affected by the non-default alignment. This tweak avoids the previously emitted warning in LLVM. Original message: This commit adds a new -Wpragma-pack warning. It warns in the following cases: - When a translation unit is missing terminating #pragma pack (pop) directives. - When entering an included file if the current alignment value as determined by '#pragma pack' directives is different from the default alignment value. - When leaving an included file that changed the state of the current alignment value. rdar://10184173 Differential Revision: https://reviews.llvm.org/D35484 llvm-svn: 309106 --- clang/test/SemaObjC/Inputs/empty.h | 1 + 1 file changed, 1 insertion(+) create mode 100644 clang/test/SemaObjC/Inputs/empty.h (limited to 'clang/test/SemaObjC/Inputs/empty.h') diff --git a/clang/test/SemaObjC/Inputs/empty.h b/clang/test/SemaObjC/Inputs/empty.h new file mode 100644 index 00000000000..6b3def4d7ae --- /dev/null +++ b/clang/test/SemaObjC/Inputs/empty.h @@ -0,0 +1 @@ +struct S { int x; }; -- cgit v1.2.3
