2012-02-04Fix a rejects-valid in C++11: array new of a negative size, or overflowing arrayRichard Smith
new, is well-formed with defined semantics of throwing (a type which can be caught by a handler for) std::bad_array_new_length, unlike in C++98 where it is somewhere nebulous between undefined behavior and ill-formed. If the array size is an integral constant expression and satisfies one of these criteria, we would previous the array new expression, but now in C++11 mode, we merely issue a warning (the code is still rejected in C++98 mode, naturally). We don't yet implement new C++11 semantics correctly (see PR11644), but we do implement the overflow checking, and (for the default operator new) convert such expressions to an exception, so accepting such code now does not seem especially unsafe. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@149767 91177308-0d34-0410-b5e6-96231b3b80d8

2012-02-04Clang has existing support for debuggers thatSean Callanan
want to provide "po"-like functionality which treats the result of an expression implicitly as "id" (if it is not otherwise known) and prints it as an Objective-C object. This has in the past been gated by the "DebuggerSupport" language option, but that is too general. Debuggers also provide other commands like "print" that do not make any assumptions about whether the object is an Objective-C object. This patch makes the assumption conditional on a new language option: DebuggerCastResultToId. I have also made corresponding modifications to the testsuite. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@149735 91177308-0d34-0410-b5e6-96231b3b80d8

2012-02-04constexpr:Richard Smith
The recent support for potential constant expressions exposed a bug in the implementation of libstdc++4.6, where numeric_limits<int>::min() is defined as (int)1 << 31, which isn't a constant expression. Disable the 'constexpr function never produces a constant expression' error inside system headers to compensate. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@149729 91177308-0d34-0410-b5e6-96231b3b80d8

2012-02-03Fix -ftrap-function fallout from llvm r145714. <rdar://problem/10799325>Bob Wilson
That llvm change removed the -trap-func backend option, so that using -ftrap-function with clang would cause the backend to complain.

2012-02-03Thread safety analysis:Richard Smith
* When we detect that a CFG block has inconsistent lock sets, point the diagnostic at the location where we found the inconsistency, and point a note at somewhere the inconsistently-locked mutex was locked. * Fix the wording of the normal (non-loop, non-end-of-function) case of this diagnostic to not suggest that the mutex is going out of scope. * Fix the diagnostic emission code to keep a warning and its note together when sorting the diagnostics into source location order. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@149669 91177308-0d34-0410-b5e6-96231b3b80d8
