2012-09-10Thread-safety analysis: differentiate between two forms of analysis; a preciseDeLesley Hutchins
analysis that may give false positives because it is confused by aliasing, and a less precise analysis that has fewer false positives, but may have false negatives. The more precise warnings are enabled by -Wthread-safety-precise. An additional note clarify the warnings in the precise case. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@163537 91177308-0d34-0410-b5e6-96231b3b80d8

2012-09-07PR9023: A template template parameter whose template parameter list contains anRichard Smith
unexpanded parameter pack is a pack expansion. Thus, as with a non-type template parameter which is a pack expansion, it needs to be expanded early into a fixed list of template parameters. Since the expanded list of template parameters is not itself a parameter pack, it is permitted to appear before the end of the template parameter list, so also remove that restriction (for both template template parameter pack expansions and non-type template parameter pack expansions). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@163369 91177308-0d34-0410-b5e6-96231b3b80d8

2012-09-05Format strings: suggest casts for NS(U)Integer and [SU]Int32 on Darwin.Jordan Rose
These types are defined differently on 32-bit and 64-bit platforms, and trying to offer a fixit for one platform would only mess up the format string for the other. The Apple-recommended solution is to cast to a type that is known to be large enough and always use that to print the value. This should only have an impact on compile time if the format string is incorrect; in cases where the format string matches the definition on the current platform, no warning will be emitted. <rdar://problem/9135072&12164284> git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@163266 91177308-0d34-0410-b5e6-96231b3b80d8
