* Support for pointers-to-members usage via .*Alexander Kornienko2013-03-201-2/+4
| | | | | | | | | | | | | | Summary: Added support for pointers-to-members usage via .* and a few tests. Reviewers: djasper Reviewed By: djasper CC: cfe-commits, klimek Differential Revision: http://llvm-reviews.chandlerc.com/D556 llvm-svn: 177537
* Remove assertion that can be triggered on bad input.Daniel Jasper2013-03-201-2/+1
| | | | | | | clang-format can't do anything useful, so it should leave the remainder of the line unchanged, but it should not assert/segfault. llvm-svn: 177530
* Fix infinite-loop in unwrapped line parser.Daniel Jasper2013-03-201-1/+1
| | | | | | Discovered when accidentally formatting a python file :-). llvm-svn: 177527
* Do not consider comments when adjusting to local indent style.Daniel Jasper2013-03-201-1/+2
| | | | | | | | | | | | | | | | Before (when only reformatting "int b"): int a; // comment // comment int b; After: int a; // comment // comment int b; This also fixes llvm.org/PR15433. llvm-svn: 177524

* Add extra indentation for multiline comparisons.Daniel Jasper2013-03-203-31/+30
| | | | | | | | | | | | | | | | This seems to be generally more desired. Before: if (aaaaaaaa && bbbbbbbb > cccccccc) {} After: if (aaaaaaaa && bbbbbbbb > cccccccc) {} Also: Some formatting cleanup on clang-format's files. llvm-svn: 177514

* Fix redundant comparison in gcc::Common::ConstructJob.Hans Wennborg2013-03-201-1/+1
| | | | | | | | | | We were checking "Arch == llvm::Triple::x86_64 || Arch == llvm::Triple::x86_64", but the rhs should actually check for powerpc64. Found while experimenting with a potential new Clang warning. llvm-svn: 177496

* Remove the Tools DensMap from the toolchain.Rafael Espindola2013-03-204-165/+204
| | | | | | | | | | 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. llvm-svn: 177479

* [ms-cxxabi] Fix assertion on unhandled function template arg typesReid Kleckner2013-03-201-49/+22
| | | | | | | | | | | | 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.

* [analyzer] Re-apply "Do part of the work to find shortest bug paths up front".Jordan Rose2013-03-201-43/+126
| | | | | | | | | | With the assurance that the trimmed graph does not contain cycles, this patch is safe (with a few tweaks), and provides the performance boost it was intended to. Part of performance work for <rdar://problem/13433687>. llvm-svn: 177469
* [analyzer] Break cycles (optionally) when trimming an ExplodedGraph.Jordan Rose2013-03-202-3/+19
| | | | | | | | | Having a trimmed graph with no cycles (a DAG) is much more convenient for trying to find shortest paths, which is exactly what BugReporter needs to do. Part of the performance work for <rdar://problem/13433687>. llvm-svn: 177468
* <rdar://problem/10796651> Introduce configuration macros into module maps.Douglas Gregor2013-03-205-6/+213
| | | | | | | | | | | | | | | | | | | | | | 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). llvm-svn: 177466
* [analyzer] Do not believe lazy binding when symbolic region types do not matchAnna Zaks2013-03-191-5/+16
| | | | | | | | | | | 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. llvm-svn: 177453
* Revert "[analyzer] Do part of the work to find shortest bug paths up front."Jordan Rose2013-03-191-115/+42
| | | | | | | | | | | | | 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. This reverts r177353 / 481fa5071c203bc8ba4f88d929780f8d0f8837ba. llvm-svn: 177448

* Finish refactoring the tool selection logic.Rafael Espindola2013-03-194-48/+26

* <rdar://problem/13363214> Eliminate race condition between module rebuild ↵Douglas Gregor2013-03-197-286/+323
| | | | | | | | | | | | | | | | | | | | | | | | | | 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. llvm-svn: 177367

* [analyzer] Do part of the work to find shortest bug paths up front.Jordan Rose2013-03-181-42/+115
| | | | | | | | | | | | | | 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.

* This code works around what appears to be a bug in another part of clang.Reed Kotler2013-03-181-1/+2
| | | | | | | | | | | | 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. But everything else is valid so I did not want to revert my previous patch for attributes mips16/nomips16 or use an llvm_unreachable here which would make a number of our tests fail for mips. llvm-svn: 177329
