2012-06-26Add template type diffing to Clang. This feature will provide a betterRichard Trieu
comparison between two templated types when they both appear in a diagnostic. Type elision will remove indentical template arguments, which can be disabled with -fno-elide-type. Cyan highlighting is applied to the differing types. For more formatting, -fdiagnostic-show-template-tree will output the template type as an indented text tree, with differences appearing inline. Template tree works with or without type elision. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@159216 91177308-0d34-0410-b5e6-96231b3b80d8
2012-06-26During codegen of a virtual call we would extract any casts in the expressionRafael Espindola
to see if we had an underlying final class or method, but we would then use the cast type to do the call, resulting in a direct call to the wrong method. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@159212 91177308-0d34-0410-b5e6-96231b3b80d8
2012-06-26block literal irgen: several improvements on naming blockFariborz Jahanian
literal helper functions. All helper functions (global and locals) use block_invoke as their prefix. Local literal helper names are prefixed by their enclosing mangled function names. Blocks in non-local initializers (e.g. a global variable or a C++11 field) are prefixed by their mangled variable name. The descriminator number added to end of the name starts off with blank (for first block) and _<N> (for the N+2-th block). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@159206 91177308-0d34-0410-b5e6-96231b3b80d8

2012-06-26Fix lifetime issue for backing APValue of OpaqueValueExpr in recursiveRichard Smith
constexpr function evaluation, and corresponding ASan / valgrind issue in tests, by storing the corresponding value with the relevant stack frame. This also prevents re-evaluation of the source of the underlying OpaqueValueExpr, which makes a major performance difference for certain contrived code (see testcase update). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@159189 91177308-0d34-0410-b5e6-96231b3b80d8

2012-06-25PR12937: Explicitly deleting an explicit template specialization.David Blaikie
This works around a quirk in the way that explicit template specializations are handled in Clang. We generate an implicit declaration from the original template which the explicit specialization is considered to redeclare. This trips up the explicit delete logic. This change only works around that strange representation. At some point it'd be nice to remove those extra declarations to make the AST more accurately reflect the C++ semantics. Review by Doug Gregor. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@159167 91177308-0d34-0410-b5e6-96231b3b80d8

2012-06-25[analyzer] Be careful about implicitly-declared operator new/delete. (PR13090)Jordan Rose
The implicit global allocation functions do not have valid source locations, but we still want to treat them as being "system header" functions for the purposes of how they affect program state. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@159160 91177308-0d34-0410-b5e6-96231b3b80d8
2012-06-25Unrevert r158887, reverted in r158949, along with a fix for the bug whichRichard Smith
resulted in it being reverted. A test for that bug was added in r158950. Original comment: If an object (such as a std::string) with an appropriate c_str() member function is passed to a variadic function in a position where a format string indicates that c_str()'s return type is desired, provide a note suggesting that the user may have intended to call the c_str() member. Factor the non-POD-vararg checking out of DefaultVariadicArgumentPromotion and move it to SemaChecking in order to facilitate this. Factor the call checking out of function call checking and block call checking, and extend it to cover constructor calls too.

2012-06-23Support the tls_model attribute (PR9788)Hans Wennborg
This adds support for the tls_model attribute. This allows the user to choose a TLS model that is better than what LLVM would select by default. For example, a variable might be declared as: __thread int x __attribute__((tls_model("initial-exec"))); if it will not be used in a shared library that is dlopen'ed. This depends on LLVM r159077. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@159078 91177308-0d34-0410-b5e6-96231b3b80d8
2012-06-23Clean up a large number of C++11 attribute parse issues, including parsingSean Hunt
attributes in more places where we didn't and catching a lot more issues. This implements nearly every aspect of C++11 attribute parsing, except for: - Attributes are permitted on explicit instantiations inside the declarator (but not preceding the decl-spec) - Attributes are permitted on friend declarations of functions. - Multiple instances of the same attribute in an attribute-list (e.g. [[noreturn, noreturn]], not [[noreturn]] [[noreturn]] which is conforming) are allowed. The first two are marked as expected-FIXME in the test file and the latter is probably a defect and is currently untested. Thanks to Richard Smith for providing the lion's share of the testcases. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@159072 91177308-0d34-0410-b5e6-96231b3b80d8

* Primarily fixed \param commands with names not matching any actual parameters of the documented functions. In many cases this consists just of fixing up the parameter name in the \param to match the code, in some it means deleting obsolete documentation and occasionally it means documenting the parameter that has replaced the older one that was documented, which sometimes means some simple reverse-engineering of the docs from the implementation; * Fixed \param ParamName [out] to the correct format with [out] before the parameter name; * Fixed some \brief summaries. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@158980 91177308-0d34-0410-b5e6-96231b3b80d8
