2012-09-28Compatibility macro detection for the -Wimplicit-fallthrough diagnostic.Alexander Kornienko
Summary: When issuing a diagnostic message for the -Wimplicit-fallthrough diagnostics, always try to find the latest macro, defined at the point of fallthrough, which is immediately expanded to "[[clang::fallthrough]]", and use it's name instead of the actual sequence. Known issues: * uses PP.getSpelling() to compare macro definition with a string (anyone can suggest a convenient way to fill a token array, or maybe lex it in runtime?); * this can be generalized and used in other similar cases, any ideas where it should reside then?

2012-09-28-Warc-repeated-use-of-weak: check ivars and variables as well.Jordan Rose
Like properties, loading from a weak ivar twice in the same function can give you inconsistent results if the object is deallocated between the two loads. It is safer to assign to a strong local variable and use that. Second half of <rdar://problem/12280249>. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@164855 91177308-0d34-0410-b5e6-96231b3b80d8
2012-09-28Add a warning (off by default) for repeated use of the same weak property.Jordan Rose
The motivating example: if (self.weakProp) use(self.weakProp); As with any non-atomic test-then-use, it is possible a weak property to be non-nil at the 'if', but be deallocated by the time it is used. The correct way to write this example is as follows: id tmp = self.weakProp; if (tmp) use(tmp); The warning is controlled by -Warc-repeated-use-of-receiver, and uses the property name and base to determine if the same property on the same object is being accessed multiple times. In cases where the base is more complicated than just a single Decl (e.g. 'foo.bar.weakProp'), it picks a Decl for some degree of uniquing and reports the problem under a subflag, -Warc-maybe-repeated-use-of-receiver. This gives a way to tune the aggressiveness of the warning for a particular project. The warning is not on by default because it is not flow-sensitive and thus may have a higher-than-acceptable rate of false positives, though it is less noisy than -Wreceiver-is-weak. On the other hand, it will not warn about some cases that may be legitimate issues that -Wreceiver-is-weak will catch, and it does not attempt to reason about methods returning weak values. Even though this is not a real "analysis-based" check I've put the bug emission code in AnalysisBasedWarnings for two reasons: (1) to run on every kind of code body (function, method, block, or lambda), and (2) to suggest that it may be enhanced by flow-sensitive analysis in the future. The second (smaller) half of this work is to extend it to weak locals and weak ivars. This should use most of the same infrastructure.

2012-09-28[analyzer] Handle inlined constructors for rvalue temporaries correctly.Jordan Rose
Previously the analyzer treated all inlined constructors like lvalues, setting the value of the CXXConstructExpr to the newly-constructed region. However, some CXXConstructExprs behave like rvalues -- in particular, the implicit copy constructor into a pass-by-value argument. In this case, we want only the /contents/ of a temporary object to be passed, so that we can use the same "copy each argument into the parameter region" algorithm that we use for scalar arguments. This may change when we start modeling destructors of temporaries, but for now this is the last part of <rdar://problem/12137950>. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@164830 91177308-0d34-0410-b5e6-96231b3b80d8
2012-09-28[analyzer] Create a temp region when a method is called on a struct rvalue.Jordan Rose
An rvalue has no address, but calling a C++ member function requires a 'this' pointer. This commit makes the analyzer create a temporary region in which to store the struct rvalue and use as a 'this' pointer whenever a member function is called on an rvalue, which is essentially what CodeGen does. More of <rdar://problem/12137950>. The last part is tracking down the C++ FIXME in array-struct-region.cpp. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@164829 91177308-0d34-0410-b5e6-96231b3b80d8
2012-09-28[analyzer] Create a temporary region for rvalue structs when accessing fieldsJordan Rose
Struct rvalues are represented in the analyzer by CompoundVals, LazyCompoundVals, or plain ConjuredSymbols -- none of which have associated regions. If the entire structure is going to persist, this is not a problem -- either the rvalue will be assigned to an existing region, or a MaterializeTemporaryExpr will be present to create a temporary region. However, if we just need a field from the struct, we need to create the temporary region ourselves. This is inspired by the way CodeGen handles calls to temporaries; support for that in the analyzer is coming next.
