2013-03-23[analyzer] Teach constraint managers about unsigned comparisons.Jordan Rose
In C, comparisons between signed and unsigned numbers are always done in unsigned-space. Thus, we should know that "i >= 0U" is always true, even if 'i' is signed. Similarly, "u >= 0" is also always true, even though '0' is signed.

2013-03-22Revert "[analyzer] Break cycles (optionally) when trimming an ExplodedGraph."Jordan Rose
The algorithm used here was ridiculously slow when a potential back-edge pointed to a node that already had a lot of successors. The previous commit makes this feature unnecessary anyway.

interaction to eliminate a pile of extraneous stats(). The refactoring in r177367 introduced a serious performance bug where the "lazy" resolution of module file names in the global module index to actual module file entries in the module manager would perform repeated negative stats(). The new interaction requires the module manager to inform the global module index when a module file has been loaded, eliminating the extraneous stat()s and a bunch of bookkeeping on both sides. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@177750 91177308-0d34-0410-b5e6-96231b3b80d8

In this case, the value of 'x' may be changed after the call to indirectAccess: struct Wrapper { int *ptr; }; void indirectAccess(const Wrapper &w); void test() { int x = 42; Wrapper w = { x }; clang_analyzer_eval(x == 42); // TRUE indirectAccess(w); clang_analyzer_eval(x == 42); // UNKNOWN } This is important for modelling return-by-value objects in C++, to show that the contents of the struct are escaping in the return copy-constructor. <rdar://problem/13239826> git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@177570 91177308-0d34-0410-b5e6-96231b3b80d8

2013-03-20Remove the Tools DensMap from the toolchain.Rafael Espindola
Each toolchain has a set of tools, but they are all of known types. It can have a linker, an assembler, a "clang" (compile, analyze, ...) a non-clang compiler, etc. Instead of keeping a map, just have member variable for each type of tool. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@177479 91177308-0d34-0410-b5e6-96231b3b80d8

2013-03-20<rdar://problem/10796651> Introduce configuration macros into module maps.Douglas Gregor
Configuration macros are macros that are intended to alter how a module works, such that we need to build different module variants for different values of these macros. A module can declare its configuration macros, in which case we will complain if the definition of a configation macro on the command line (or lack thereof) differs from the current preprocessor state at the point where the module is imported. This should eliminate some surprises when enabling modules, because "#define CONFIG_MACRO ..." followed by "#include <module/header.h>" would silently ignore the CONFIG_MACRO setting. At least it will no longer be silent about it. Configuration macros are eventually intended to help reduce the number of module variants that need to be built. When the list of configuration macros for a module is exhaustive, we only need to consider the settings for those macros when building/finding the module, which can help isolate modules for various project-specific -D flags that should never affect how modules are build (but currently do). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@177466 91177308-0d34-0410-b5e6-96231b3b80d8

2013-03-19Finish refactoring the tool selection logic.Rafael Espindola
The general pattern now is that Foobar::constructTool only creates tools defined in the tools::foobar namespace and then delegates to the parent. The remaining duplicated code is now in the tools themselves. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@177368 91177308-0d34-0410-b5e6-96231b3b80d8
2013-03-19<rdar://problem/13363214> Eliminate race condition between module rebuild ↵Douglas Gregor
and the global module index. The global module index was querying the file manager for each of the module files it knows about at load time, to prune out any out-of-date information. The file manager would then cache the results of the stat() falls used to find that module file. Later, the same translation unit could end up trying to import one of the module files that had previously been ignored by the module cache, but after some other Clang instance rebuilt the module file to bring it up-to-date. The stale stat() results in the file manager would trigger a second rebuild of the already-up-to-date module, causing failures down the line. The global module index now lazily resolves its module file references to actual AST reader module files only after the module file has been loaded, eliminating the stat-caching race. Moreover, the AST reader can communicate to its caller that a module file is missing (rather than simply being out-of-date), allowing us to simplify the module-loading logic and allowing the compiler to recover if a dependent module file ends up getting deleted. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@177367 91177308-0d34-0410-b5e6-96231b3b80d8
