Lang Hames 92f9dd24ac [Orc] Add a JITSymbol class to the Orc APIs, refactor APIs, update clients. ... This patch refactors a key piece of the Orc APIs: It removes the *::getSymbolAddress and *::lookupSymbolAddressIn methods, which returned target addresses (uint64_ts), and replaces them with *::findSymbol and *::findSymbolIn respectively, which return instances of the new JITSymbol type. Unlike the old methods, calling findSymbol or findSymbolIn does not cause the symbol to be immediately materialized when found. Instead, the symbol will be materialized if/when the getAddress method is called on the returned JITSymbol. This allows us to query for the existence of symbols without actually materializing them. In the future I expect more information to be attached to the JITSymbol class, for example whether the returned symbol is a weak or strong definition. This will allow us to properly handle weak symbols and multiple definitions. llvm-svn: 228557		2015-02-09 01:20:51 +00:00
