8f1e44f1b7 Stricter false positive testing: Perform old and new check on uninitialized variables false positives tests (with a few exceptions for FP in old checker that don't exist in the new one) 2015-01-21 16:45:15 +01:00

5334aaa25f Refactorization: 
- Removed a few unit tests of old uninitialized variable checking expecting other results than same test for new checking
- A few tweaks to new uninitvar checking to improve results when run on tests for old check
- switched some (TODO) tests to new check if the TODO is fixed

ec21134817 Fix false negatives for local suppressions 
Introduce a new bool setting jointSuppressionReport
that will be set by the analyseWholeProgram() code path.

When the flag is enabled, unmatched suppressions are
collected after running the final whole program analysis
to prevent false positives for the unusedFunction check.

The check functions in the unit test
for single / multi file suppressions were unified.

58cb6cc116 Add new "style" check to catch redundant pointer operations 
Doing "&*some_ptr_var" is redundant and might be the remainder
of a refactoring. Warnings for expanded macros are excluded though:
They are often used with and without pointers and
do something like this: "func(&(*macroarg))".

The new check is fully AST based and was given
strong false positive testing on a large code base.

1cc85bfce3 Add bounds check to getVariableFromVarId() 
While poking around the memory leak check,
I managed to trigger an out-of-bounds access
in the symbol database.

Fix it by sanity checking the variable id
passed to getVariableFromVarId().
