Lang Hames 69d7550bd6 [Support] Add the 'Error' class for structured error handling. ... This patch introduces the Error classs for lightweight, structured, recoverable error handling. It includes utilities for creating, manipulating and handling errors. The scheme is similar to exceptions, in that errors are described with user-defined types. Unlike exceptions however, errors are represented as ordinary return types in the API (similar to the way std::error_code is used). For usage notes see the LLVM programmer's manual, and the Error.h header. Usage examples can be found in unittests/Support/ErrorTest.cpp. Many thanks to David Blaikie, Mehdi Amini, Kevin Enderby and others on the llvm-dev and llvm-commits lists for lots of discussion and review. llvm-svn: 263609		2016-03-16 01:02:46 +00:00
