vbalu updated this revision to Diff 98762.
vbalu added a comment.
Modified as per suggested. I used the flag option "flagsParsedVariables" to
monitor if global variable are completely parsed or not.
Looks like it never used. For a compile unit global variable will be parsed
only through the method "GetVariableList" so i set the flag there.
