Saleem Abdulrasool	d2c5d7f6da	Transforms: address some late comments ... We already use the llvm namespace. Remove the unnecessary prefix. Use the StringRef::equals method to compare with C strings rather than instantiating std::strings. Addresses late review comments from David Majnemer. llvm-svn: 221564	2014-11-08 00:00:50 +00:00
Saleem Abdulrasool	89c5ad4cda	Transforms: use typedef rather than using aliases ... Visual Studio 2012 apparently does not support using alias declarations. Use the more traditional typedef approach. This should let the Windows buildbots pass. NFC. llvm-svn: 221554	2014-11-07 22:09:52 +00:00
Saleem Abdulrasool	5898e09057	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. llvm-svn: 221548	2014-11-07 21:32:08 +00:00
