Saleem Abdulrasool	08aea7d1b6	SymbolRewriter: allow rewriting with comdats ... COMDATs must be identically named to the symbol. When support for COMDATs was introduced, the symbol rewriter was not updated, resulting in rewriting failing for symbols which were placed into COMDATs. This corrects the behaviour and adds test cases for this. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@227261 91177308-0d34-0410-b5e6-96231b3b80d8	2015-01-27 22:57:39 +00:00
Saleem Abdulrasool	35c163020a	Transform: add SymbolRewriter pass ... This introduces the symbol rewriter. This is an IR->IR transformation that is implemented as a CodeGenPrepare pass. This allows for the transparent adjustment of the symbols during compilation. It provides a clean, simple, elegant solution for symbol inter-positioning. This technique is often used, such as in the various sanitizers and performance analysis. The control of this is via a custom YAML syntax map file that indicates source to destination mapping, so as to avoid having the compiler to know the exact details of the source to destination transformations. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@221548 91177308-0d34-0410-b5e6-96231b3b80d8	2014-11-07 21:32:08 +00:00
