* Fix handling of invalid uses of the __has_warning builtin macroAndy Gibbs2012-11-174-3/+19
| | | | llvm-svn: 168265
* Enable inlining of 4 byte atomic ops on ppc32, 8 byte atomic ops on ppc64.Benjamin Kramer2012-11-173-6/+45
| | | | | | Also fixes a bit/byte mismatch when checking if a target supports atomic ops of a certain size. llvm-svn: 168260
* Remove copy ctor that provides no value over the default.Benjamin Kramer2012-11-171-2/+0
| | | | | | It's also simpler to just copy the words than mangling bits like this ctor did. llvm-svn: 168258
* Further reduce "-fsyntax-only -Wuninitialized" time on sqlite3.c by another ↵Ted Kremenek2012-11-171-12/+52
| | | | | | 2.5% using intelligent pruning of blocks during the final reporting pass. llvm-svn: 168257
* Switch -Wuninitialized to use a reverse-post order traversal asTed Kremenek2012-11-171-15/+33
| | | | | | | | | an initial baseline for enqueued blocks, but use a simple DFS stack for propagating changes quickly up back edges. This provides a 3.5% reduction in -fsyntax-only time on sqlite3.c. llvm-svn: 168241

* [driver] Add the missing TY_PP_ObjCXX_Alias case to the isCXX function.Chad Rosier2012-11-162-1/+7
| | | | | | | | | This was causing different behavior when using -x objective-c++-cpp-output as compared to -x objc++-cpp-output. Specifically, the driver was not adding the -fcxx-exceptions flag in the latter case. rdar://12680312 llvm-svn: 168212
* StmtDumper: remove incomplete support for limiting the maximum dump depth.Dmitri Gribenko2012-11-162-40/+7
| | | | | | | | | There are better ways of limiting the amount of information if there is a need for that. Patch by Philip Craig. llvm-svn: 168206
* Fix partial-match-bind-behavior with forEachDescendant() matchers.Daniel Jasper2012-11-162-2/+21
| | | | | | | | | | | | | | | | The problem is that a partial match of an (explicit or implicit) allOf matcher binds results, i.e. recordDecl(decl().bind("x"), hasName("A")) can very well bind a record that is not named "A". With this fix, the common cases of stumbling over this bug are fixed by the BoundNodesMap overwriting the results of a partial match. An error can still be created with a weird combination of anyOf and allOf (see inactive test). We need to decide whether this is worth fixing, as the fix will have performance impact.

* [analyzer] SATestBuild.py: fix broken string concatenationJordan Rose2012-11-161-2/+2
| | | | | | | | This has been broken for a while, but the branch was never being taken. (We were trying to do 'str + floatVal'; now we do 'str % intVal' and use the '%d' format.) llvm-svn: 168174

| | | | | | | | libRewriteCore. LLVM_USED_LIBS does nothing here. llvm-svn: 168172

* [libclang] When caching code-completion results, pass the ↵Argyrios Kyrtzidis2012-11-161-4/+5
| | | | | | | | | | | | | | CachedCompletionAllocator to the CodeCompletionTUInfo that is going to be used to get the results. Previously we would use ASTUnit's CodeCompletionTUInfo which has its own allocator that will go away when we reparse. That could result in a use-after-free bug when getting the parent context name from a CodeCompletionString. Addresses rdar://12568377. llvm-svn: 168133
* clang/test/lit.cfg: Suppress the feature 'dev-fd-fs' for now.NAKAMURA Takumi2012-11-161-1/+1
| | | | | | None of my buildhost (centos6 x86-64 and cygwin) is passing. Investigating. llvm-svn: 168132
* CPP Output: Do not emit an enter file marker for the main file.Daniel Dunbar2012-11-162-0/+15
| | | | | | | | - This diverges from gcc, and confuses tools (like dtrace) which track # line markers as a way to determine which content is in the context of the main file. llvm-svn: 168128
* Take into account the zero sign bit for positive numbers when computing the bitRichard Trieu2012-11-162-1/+15
| | | | | | | width of an enum with negative values in IntRange. Include a test for -Wtautological-constant-out-of-range-compare where this had manifested. llvm-svn: 168126
* Fix PR14321, a crash when Clang is built with GCC 4.7 at -O1 or greater.Matt Beaumont-Gay2012-11-161-1/+1
| | | | | | | | | GCC 4.7 reuses stack slots fairly aggressively, which exposes more temporary lifetime bugs. No new test, this was caught by the existing CodeGenCXX/mangle-ms-templates.cpp. llvm-svn: 168124
* A step towards sorting out handling of triviality of special members in C++11.Richard Smith2012-11-1610-74/+126
| | | | | | | | | | | | | | Separate out the notions of 'has a trivial special member' and 'has a non-trivial special member', and use them appropriately. These are not opposites of one another (there might be no special member, or in C++11 there might be a trivial one and a non-trivial one). The CXXRecordDecl predicates continue to produce incorrect results, but do so in fewer cases now, and they document the cases where they might be wrong. No functionality changes are intended here (they will come when the predicates start producing the right answers...). llvm-svn: 168119

* [analyzer] Fix a use-after-free introduced in r168019.Jordan Rose2012-11-151-4/+5
| | | | | | | | | | | | | | | | | | | | | | | In code like this: void foo() { bar(); baz(); } ...the location for the call to 'bar()' was being used as a backup location for the call to 'baz()'. This is fine unless the call to 'bar()' is deemed uninteresting and that part of the path deleted. (This looks like a logic error as well, but in practice the only way 'baz()' could have an invalid location is if the entire body of 'foo()' is synthesized, meaning the call to 'bar()' will be using the location of the call to 'foo()' anyway. Nevertheless, the new version better matches the intent of the code.) Found by Matt Beaumont-Gay using ASan. Thanks, Matt! llvm-svn: 168080
* tests: Add a test for reading from named pipes.Daniel Dunbar2012-11-152-0/+16

* [analyzer] Report leaks at the closing brace of a function body.Jordan Rose2012-11-1514-213/+180
| | | | | | | | | | | | | | | | | | | | This fixes a few cases where we'd emit path notes like this: +---+ 1| v p = malloc(len); ^ |2 +---+ In general this should make path notes more consistent and more correct, especially in cases where the leak happens on the false branch of an if that jumps directly to the end of the function. There are a couple places where the leak is reported farther away from the cause; these are usually cases where there are several levels of nested braces before the end of the function. This still matches our current behavior for when there /is/ a statement after all the braces, though. llvm-svn: 168070
* [analyzer] StreamChecker: Remove now-unnecessary check::EndPath callback.Jordan Rose2012-11-151-46/+1
| | | | | | | Also, don't bother to stop tracking symbols in the return value, either. They are now properly considered live during checkDeadSymbols. llvm-svn: 168069

| | | | | | | Also, don't bother to stop tracking symbols in the return value, either. They are now properly considered live during checkDeadSymbols. llvm-svn: 168068
* [analyzer] MallocChecker: Remove now-unnecessary check::EndPath callback.Jordan Rose2012-11-151-29/+1
| | | | | | | Also, don't bother to stop tracking symbols in the return value, either. They are now properly considered live during checkDeadSymbols. llvm-svn: 168067
* [analyzer] Mark symbol values as dead in the environment.Jordan Rose2012-11-157-184/+262
| | | | | | | | | | | | | | This allows us to properly remove dead bindings at the end of the top-level stack frame, using the ReturnStmt, if there is one, to keep the return value live. This in turn removes the need for a check::EndPath callback in leak checkers. This does cause some changes in the path notes for leak checkers. Previously, a leak would be reported at the location of the closing brace in a function. Now, it gets reported at the last statement. This matches the way leaks are currently reported for inlined functions, but is less than ideal for both. llvm-svn: 168066
