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