* | Add a new function attribute 'cold' to functions. | Diego Novillo | 2013-05-24 |
Other than recognizing the attribute, the patch does little else. It changes the branch probability analyzer so that edges into blocks postdominated by a cold function are given low weight. Added analysis and code generation tests. Added documentation for the new attribute. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@182638 91177308-0d34-0410-b5e6-96231b3b80d8 |
