From fe45fd084db872f9c7106c26e52c1cc8c9cba3a5 Mon Sep 17 00:00:00 2001 From: Paul Robinson Date: Mon, 18 Nov 2013 21:44:03 +0000 Subject: The 'optnone' attribute means don't inline anything into this function (except functions marked always_inline). Functions with 'optnone' must also have 'noinline' so they don't get inlined into any other function. Based on work by Andrea Di Biagio. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@195046 91177308-0d34-0410-b5e6-96231b3b80d8 --- docs/LangRef.rst | 5 +++-- 1 file changed, 3 insertions(+), 2 deletions(-) (limited to 'docs') diff --git a/docs/LangRef.rst b/docs/LangRef.rst index f7914f864f..18d2c9cfb5 100644 --- a/docs/LangRef.rst +++ b/docs/LangRef.rst @@ -941,9 +941,10 @@ example: attribute; this attribute is also incompatible with the ``minsize`` attribute and the ``optsize`` attribute. - The inliner should never inline this function in any situation. + This attribute requires the ``noinline`` attribute to be specified on + the function as well, so the function is never inlined into any caller.
