New Revision: 175062

URL: http://gcc.gnu.org/viewcvs?root=gcc&view=rev&rev=175062
Log:
Enhance Annotalysis to support cloned functions/methods (especially
created by IPA-SRA). The patch basically does the following:

1. For a FUNCTION_DECL, check whether it's a clone, and if so, grab its
original DECL.
2. Deal with the situation where a reference/pointer parameter is converted
to a value parameter or even optimized away by IPA-SRA.
