Hi Rahul,
First, open Project Properties and check C/C++ General -> Path and
Symbols, the "Source Location" tab. Make sure that "llvm" (the root of
the source) directory appears in the "Source folders on build path"
list.

Another option is to go to Window -> Preferences, C/C++, Code Analysis
and turn off "Syntax and semantic errors"
