Detailed Description

The basic entity representing a rewrite operation.

It serves as the base class for any rewrite descriptor. It has a certain set of specializations which describe a particular rewrite.

The RewriteMapParser can be used to parse a mapping file that provides the mapping for rewriting the symbols. The descriptors individually describe whether to rewrite a function, global variable, or global alias. Each of these can be selected either by explicitly providing a name for the ones to be rewritten or providing a (posix compatible) regular expression that will select the symbols to rewrite. This descriptor list is passed to the SymbolRewriter pass.
