2013-03-20The flag "-coverage-function-names-in-data" is actually backwards -- we doNick Lewycky
emit function names in .gcda files by default, and the flag turns that off! Rename the flag to make it match what it actually does. This keeps the default format compatible with gcc 4.2.

2013-03-20[ms-cxxabi] Fix assertion on unhandled function template arg typesReid Kleckner
This code was changed in r158376 to get template argument source info for better diagnostics, but the current code asserts for any kind of unsupported template argument before it can issue a diagnostic. This change goes back to the Itanium implementation of isTemplate() and puts the argument index into the diagnostic instead of a source location.

2013-03-20[analyzer] Re-apply "Do part of the work to find shortest bug paths up front".Jordan Rose

2013-03-20[analyzer] Break cycles (optionally) when trimming an ExplodedGraph.Jordan Rose

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

2013-03-19[analyzer] Do not believe lazy binding when symbolic region types do not matchAnna Zaks
This fixes a crash when analyzing LLVM that was exposed by r177220 (modeling of trivial copy/move assignment operators). When we look up a lazy binding for “Builder”, we see the direct binding of Loc at offset 0. Previously, we believed the binding, which led to a crash. Now, we do not believe it as the types do not match. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@177453 91177308-0d34-0410-b5e6-96231b3b80d8

2013-03-19Revert "[analyzer] Do part of the work to find shortest bug paths up front."Jordan Rose
The whole reason we were doing a BFS in the first place is because an ExplodedGraph can have cycles. Unfortunately, my removeErrorNode "update" doesn't work at all if there are cycles. I'd still like to be able to avoid doing the BFS every time, but I'll come back to it later.

2013-03-19cindex.py: Handle NULL pointers when parsing translation unitsTobias Grosser
The code inside cindex.py was comparing NULL pointer returned by clang_parseTranslationUnit and clang_createTranslationUnit with None. However, as illustrated by the two tests I've added, those conditions were ineffective which resulted in assert triggering later on. Instead, a pointer is now treated as a boolean value, a NULL pointer being False.

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

2013-03-18[analyzer] Do part of the work to find shortest bug paths up front.Jordan Rose
Splitting the graph trimming and the path-finding (r177216) already recovered quite a bit of performance lost to increased suppression. We can still do better by also performing the reverse BFS up front (needed for shortest-path-finding) and only walking the shortest path for each report. This does mean we have to walk back up the path and invalidate all the BFS numbers if the report turns out to be invalid, but it's probably still faster than redoing the full BFS every time.

I have filed http://llvm.org/bugs/show_bug.cgi?id=15538 against clang. This code is safer anyway because "cast" assumes you really know that it's okay to make the cast. In this case isa should not be false and dyn_cast should not return null as far as I understand.
