[cfe-dev] how can i get ud-chain of variable in checker?

[종모님 via cfe-dev]

i did clang static analyzer checker guide and i build it. it works
successfully.

and i have a 2 question.

Q1. I know that the Clang tool provides a du-chain. how can i get
du(define-use)-chain in checker? - i need du-chain for analysis

Q2. Analyze a file with the specified checker is fail. normal package
checker is works.

$clang --analyze -Xanalyzer -analyzer-checker=alpha test.c

-> it works.

$clang --analyze -Xanalyzer -analyzer-checker=alpha.core test.c

-> it fail. (I guess the argument changed.)
