Ted Kremenek 627c3074dd Improve leak diagnostics to not report a leak on the same line where
the object was last used.  This can be confusing to users.

For example:

 // 'y' is leaked
x = foo(y);

instead:

x = foo(y);
  // 'y' is leaked

Ted Kremenek db04a9e967 When reporting branch conditions that evaluate to an uninitialized value,
highlight the most nested subexpression that appears most responsible (giving

Chris Lattner 3565c8e343 Neil pointed out that clang doesn't generate ranges from diagnostics
related to pp-expressions.  Doing so is pretty simple and this
patch implements it, yielding nice diagnostics like:

t.c:2:7: error: division by zero in preprocessor expression
#if 1 / (0 + 0)
    ~ ^ ~~~~~~~
t.c:5:14: error: expected ')' in preprocessor expression
#if (412 + 42
     ~~~~~~~~^
t.c:5:5: error: to match this '('
#if (412 + 42
    ^
t.c:10:10: warning: left side of operator converted from negative value to unsigned: -42 to 18446744073709551574
#if (-42 + 0U) / -2
     ~~~ ^ ~~
t.c:10:16: warning: right side of operator converted from negative value to unsigned: -2 to 18446744073709551614
#if (-42 + 0U) / -2

Steve Naroff f8ecff2a94 Replace Sema::CheckInitializerListTypes() with a helper class (InitListChecker) that synthesizes implicit InitListExpr's when appropriate (see InitListExpr comments in Expr.h for more details). I also moved the code to SemaInit.cpp, to help reduce clutter in SemaDecl.cpp.
NOTE: This work is incomplete and still fails many tests (as a result, it isn't enabled yet). Nevertheless, I wanted to check it in so I can work on it from home.

Ted Kremenek fa5a3d0fe7 Major rewrite/refactoring of static analysis engine. We now use
EvalStore/EvalLoad to handle all loads/stores from symbolic memory, allowing us
to do checks for null dereferences, etc., at any arbitrary load/store (these
were missed checks before). This also resulted in some major cleanups, some
conceptual, and others just in the structure of the code.

This temporarily introduces a regression in the test suite (null-deref-ps.c)
before I add a new LVal type for structure fields.

llvm-svn: 50176
2008-04-23 20:12:28 +00:00
Ted Kremenek 467297ab48 TranslationUnit now owns IdentifierTable, TargetInfo, and Selectors objects
when it is constructed via deserialization.  This is done by recording a flag
indicating that this is the case, and it deletes these objects by getting
the references stored in the ASTContext object.  This fixes some memory
leaks that occurs when we deserialize translation units from bitcode files.

The rationale between having TranslationUnit sometimes own these objects and
sometimes not is that a TranslationUnit object can be constructed from
state generated by the parser (Preprocessor; semantic analyzer, etc.), and thus
in these cases won't own the IdentifierTable or Selectors, etc.  During
deserialization, there is no Preprocessor, so somebody needs to own these
objects in order for them to be properly reclaimed.

Ted Kremenek cffe635699 Simplified internal logic of BugReporter, consolidating EmitWarning and
EmitPathWarning into one method.  We now properly handle emitting warnings
without a PathDiagnosticClient when the warning does not involve a particular

Ted Kremenek f42f3fb47d class Preprocessor: Now owns the "predefines" char*; it deletes [] it in its dstor.
clang.cpp: InitializePreprocessor now makes a copy of the contents of PredefinesBuffer and
  passes it to the preprocessor object.
  
clang.cpp: DriverPreprocessorFactory now calls "InitializePreprocessor" instead of this being done in main().

html::HighlightMacros() now takes a PreprocessorFactory, allowing it to conjure up a new
Preprocessor to highlight macros.

class HTMLDiagnostics now takes a PreprocessorFactory* that it can use for html::HighlightMacros().
Updated clients of HTMLDiagnostics to use this new interface.

Chris Lattner 7c7e9b3bbe Handle text escaping (e.g. & -> &amp;) last, to avoid interactions between 'replace' operations and insert operations. This fixes a problem with "&;&" on line 666 of the gcc.c example I sent out.

Refactored LiveVariables to use getTerminatorCondition() in VisitTerminator().

Bug fix: CFG now computes Block-level expression numbers using information
from block terminators.  This fixes <rdar://problem/5868189>.

Chris Lattner 0bb0e7ee8a switch from relexing with the preprocessor to do syntax highlighting to relexing

comments.  Comments to be restored later.

Ted Kremenek f2e6fcf3bf Hook up HTMLDiagnostics to use Chris's new syntax highlighting. --html-diags

worklist when the other is empty.  Exploration of the graph is still in
reverse-BFS.
