PKEuS 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

PKEuS 54de731cac Refactorized CheckUninitVar::checkScope(), fixed false negative 2015-01-21 12:20:03 +01:00
PKEuS 5f36c7c914 Improved detection of Type::needInitialization:
- Implement shortcut for C code - all types need initialization there
- Break out of loop faster if we encounter a type that needs initialization (it is sufficient if one member needs initialization)

Thomas Jarosch 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.

Thomas Jarosch cd4c297dce Fix segfault in template simplifier
When something parsing the template syntax
went wrong, "tok2" was NULL and resulted
in deleting all remaining tokens. Whoops.

Triggered by gcc test suite:
gcc/testsuite/g++.dg/cpp0x/variadic87.C

Tracked down the source of the bug with
valgrind's "--track-origins=yes" switch.

Thomas Jarosch 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.

Thomas Jarosch 2bcd675653 Verbose AST dump: Show if token is expanded from macro
I also added the token variable id, but that decreased
readability of the AST tree too much.

Thomas Jarosch 10fffbfce0 Use unsigned int for all flags
Frank Zingsheim reported: With the parameter 'flag_'
and the member variable '_flags' having the type 'int'
produces a lot of warings in clang:

"warning: implicit conversion changes signedness: 'int' to 'unsigned int'".

Thomas Jarosch 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().
