* Get less confused by trailing comma in Google style.Daniel Jasper2013-02-141-1/+2
| | | | | | | | | | | | | | | | | The formatter can now format: void aaaaaaaaaaaaaaaaaa(int level, double *min_x, double *max_x, double *min_y, double *max_y, double *min_z, double *max_z, ) { } Although this is invalid code, it frequently happens during development and clang-format should be nicer :-). llvm-svn: 175151
* Align superclasses for multiple inheritence.Daniel Jasper2013-02-143-2/+14

* Pass the target options through to code generation.Bill Wendling2013-02-145-10/+31
| | | | | | | The code generation stuff is going to set attributes on the functions it generates. To do that it needs the target options. Pass them through. llvm-svn: 175141

| | | | | | | static functions in extern "C" contexts are mangled. Should fix the bootstrap. llvm-svn: 175132
* merge hasCLanguageLinkage and isExternC. Keep the shorter name.Rafael Espindola2013-02-144-65/+35
| | | | | | | | | | I added hasCLanguageLinkage while fixing some language linkage bugs some time ago so that I wouldn't have to check all users of isExternC. It turned out to be a much longer detour than expected, but this patch finally merges the two again. The isExternC function now implements just the standard notion of having C language linkage. llvm-svn: 175119
* Add a getLanguageLinkage method to VarDecls and FunctionDecls. Use it to fixRafael Espindola2013-02-144-26/+59
| | | | | | | | | | | | | | | some cases where functions with no language linkage were being treated as having C language linkage. In particular, don't warn in extern "C" { static NonPod foo(); } Since getLanguageLinkage checks the language linkage, the linkage computation cannot use the language linkage. Break the loop by checking just the context in the linkage computation. llvm-svn: 175117

| | | | | | | base-to-derived casts have undefined behavior if the object is not actually an instance of the derived type. llvm-svn: 175078
* Allow breaking after the return type in function declarations.Daniel Jasper2013-02-132-6/+9
| | | | | | | | | | | | | | | | | This has so far been disabled for Google style, but should be done before breaking at nested name specifiers or in template parameters. Before (in Google style): template <typename T> aaaaaaaa::aaaaa::aaaaaa<T, aaaaaaaaaaaaaaaaaaaaaaaaa> aaaaaaaaaaaaaaaaaaaaaaaa< T>::aaaaaaa() {} After: template <typename T> aaaaaaaa::aaaaa::aaaaaa<T, aaaaaaaaaaaaaaaaaaaaaaaaa> aaaaaaaaaaaaaaaaaaaaaaaa<T>::aaaaaaa() {} llvm-svn: 175074
* Fix comment alignment close to the column limit.Daniel Jasper2013-02-131-1/+1
| | | | | | | Due to an error in one of the expressions, we used to not align comments although it would have been possible. llvm-svn: 175068

| | | | | | Fix some comments. llvm-svn: 175052
* An attempt to make the search algorithm easier to understand.Manuel Klimek2013-02-131-49/+86
| | | | | | | | | | | | | | | | | | | | - clear ownership: the SpecificBumpPtrAllocator owns all StateNodes - this allows us to simplify the memoization data structure into a std::set (FIXME: figure out whether we want to use a hash based data structure). - introduces StateNode as recursive data structure, instead of using Edge and the Seen-map combined to drill through the graph - using a count to stabilize the penalty instead of relying on the container - pulled out a method to forward-apply states in the end This leads to a ~40% runtime decrease on Nico's benchmark. Main FiXME is that the parameter lists of some function get too long. I'd vote for either pulling the Queue etc into the Formatter proper, or creating an inner class just for the search algorithm. llvm-svn: 175051

* [analyzer] Use Clang's evaluation for global constants and default arguments.Jordan Rose2013-02-133-10/+41
| | | | | | | | | | | Previously, we were handling only simple integer constants for globals and the smattering of implicitly-valued expressions handled by Environment for default arguments. Now, we can use any integer constant expression that Clang can evaluate, in addition to everything we handled before. PR15094 / <rdar://problem/12830437> llvm-svn: 175026

| | | | | | | Still the formatting can be improved, but at least we don't assert any more. This happened when trying to format lib/Sema/SemaType.cpp. llvm-svn: 175003

* Accept over-qualified constructor in MSVC emulation modeDmitri Gribenko2013-02-121-6/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | MSVC accepts this: class A { A::A(); }; Clang accepts regular member functions with extra qualification as an MS extension, but not constructors. This changes the parser to defer rejecting qualified constructors so that the same Sema logic can apply to constructors as regular member functions. This also improves the error message when MS extensions are disabled (in my opinion). Before it was: /Users/jason/Desktop/test.cpp:2:8: error: expected member name or ';' after declaration specifiers A::A(); ~~~~ ^ 1 error generated. After: /Users/jason/Desktop/test.cpp:2:6: error: extra qualification on member 'A' A::A(); ~~~^ 1 error generated. Patch by Jason Haslam. llvm-svn: 174980

* Formatter: Correctly format stars in `sizeof(int**)` and similar places.Nico Weber2013-02-121-14/+20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This redoes how '*' and '&' are classified as pointer / reference markers when followed by ')', '>', or ','. Previously, determineStarAmpUsage() marked a single '*' and '&' followed by ')', '>', or ',' as pointer or reference marker. Now, all '*'s and '&'s preceding ')', '>', or ',' are marked as pointer / reference markers. Fixes PR14884. Since only the last '*' in 'int ***' was marked as pointer before (the rest were unary operators, which don't reach spaceRequiredBetween()), spaceRequiredBetween() now had to be thought about handing multiple '*'s in sequence. Before: return sizeof(int * *); Type **A = static_cast<Type * *>(P); Now: return sizeof(int**); Type **A = static_cast<Type **>(P); While here, also make all methods of AnnotatingParser except parseLine() private.

* The meat of this patch is in BuildCXXMemberCalLExpr where we make it useNick Lewycky2013-02-125-13/+15
| | | | | | | | | | | | MarkMemberReferenced instead of marking functions referenced directly. An audit of callers to MarkFunctionReferenced and DiagnoseUseOfDecl also caused a few other changes: * don't mark functions odr-used when considering them for an initialization sequence. Do mark them referenced though. * the function nominated by the cleanup attribute should be diagnosed. * operator new/delete should be diagnosed when building a 'new' expression. llvm-svn: 174951

* When generating IR for default copy-constructors, copy-assignment operators,Lang Hames2013-02-113-1/+364
| | | | | | | | | | | | | | | | | | | | move-constructors and move-assignment operators, use memcpy to copy adjacent POD members. Previously, classes with one or more Non-POD members would fall back on element-wise copies for all members, including POD members. This often generated a lot of IR. Without padding metadata, it wasn't often possible for the LLVM optimizers to turn the element-wise copies into a memcpy. This code hasn't yet received any serious tuning. I didn't see any serious regressions on a self-hosted clang build, or any of the nightly tests, but I think it's important to get this out in the wild to get more testing. Insights, feedback and comments welcome. Many thanks to David Blaikie, Richard Smith, and especially John McCall for their help and feedback on this work. llvm-svn: 174919

* [Modules] Cope better with top-level declarations loaded after being ↵Douglas Gregor2013-02-112-3/+31
| | | | | | | | | | | | | | | | | | | | declared in the current translation unit <rdar://problem/13189985>. These two related tweaks to keep the information associated with a given identifier correct when the identifier has been given some top-level information (say, a top-level declaration) and more information is then loaded from a module. The first ensures that an identifier that was "interesting" before being loaded from an AST is considered to be different from its on-disk counterpart. Otherwise, we lose such changes when writing the current translation unit as a module. Second, teach the code that injects AST-loaded names into the identifier chain for name lookup to keep the most recent declaration, so that we don't end up confusing our declaration chains by having a different declaration in there. llvm-svn: 174895
* Formatter: Detect ObjC message expressions after 'in' in loopNico Weber2013-02-113-6/+22
| | | | | | | | | | | | | | | | Before: for (id foo in[self getStuffFor : bla]) { } Now: for (id foo in [self getStuffFor:bla]) { } "in" is treated as loop keyword if the line starts with "for", and as a regular identifier else. To check for "in", its IdentifierInfo is handed through a few layers. llvm-svn: 174889

* Fix invalid formatting with spaces before trailing comments.Daniel Jasper2013-02-113-9/+11
| | | | | | | | In google style, trailing comments are separated by two spaces. This patch fixes the counting of these spaces and prevents clang-format from creating a line with 81 columns. llvm-svn: 174879
* Fixes handling of empty lines in macros.Manuel Klimek2013-02-112-4/+6

* Formatter: Remove now-unneeded code for formatting ':'s in ObjC method decls.Nico Weber2013-02-101-21/+0
| | | | | | | The more general code for formatting ObjC method exprs does this and more, it's no longer necessary to special-case this. No behavior change. llvm-svn: 174843
* Formatter: Initial support for ObjC dictionary literals.Nico Weber2013-02-101-1/+16

* Use -mno-implicit-float by default for kernel/kext code. <rdar://13177960>Bob Wilson2013-02-101-4/+12
| | | | | | | | | | | Apple's kernel engineers have been expecting this behavior even though we've never implemented it before, as far as I can tell. In recent months, clang has gotten better at using vector instructions to optimize memcpy-like operations, and that has exposed problems when vector/floating-point instructions are used in kexts that don't support that. This behavior also matches what Apple's GCC did for PowerPC targets. llvm-svn: 174838
