Add function attribute 'optnone'. This function attribute indicates that the function is not optimized by any optimization or code generator passes with the exception of interprocedural optimization passes. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@189101 91177308-0d34-0410-b5e6-96231b3b80d8 2013-08-23 11:53:55 +00:00			`; RUN: llvm-as < %s \| llvm-dis \| FileCheck %s`

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 2013-11-18 21:44:03 +00:00			`; Check for the presence of attribute optnone in the disassembly.`
