SymbolRewriter: allow rewriting with comdats

2015-01-27T22:57:39+00:00

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. llvm-svn: 227261

Transform: add SymbolRewriter pass

2014-11-07T21:32:08+00:00

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
