2012-06-26Add template type diffing to Clang. This feature will provide a betterRichard Trieu
comparison between two templated types when they both appear in a diagnostic. Type elision will remove indentical template arguments, which can be disabled with -fno-elide-type. Cyan highlighting is applied to the differing types. For more formatting, -fdiagnostic-show-template-tree will output the template type as an indented text tree, with differences appearing inline. Template tree works with or without type elision. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@159216 91177308-0d34-0410-b5e6-96231b3b80d8

2012-06-26block literal irgen: several improvements on naming blockFariborz Jahanian
literal helper functions. All helper functions (global and locals) use block_invoke as their prefix. Local literal helper names are prefixed by their enclosing mangled function names. Blocks in non-local initializers (e.g. a global variable or a C++11 field) are prefixed by their mangled variable name. The descriminator number added to end of the name starts off with blank (for first block) and _<N> (for the N+2-th block). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@159206 91177308-0d34-0410-b5e6-96231b3b80d8

2012-06-20Fix a big layering violation introduced by r158771.Chandler Carruth
That commit added a new library just to hold the RawCommentList. I've started a discussion on the commit thread about whether that is really meritted -- it certainly doesn't seem necessary at this stage. However, the immediate problem is that the AST library has a hard dependency on the Comment library, but the dependencies were set up completely backward. In addition to the layering violation, this had an unfortunate effect if scattering the Comments library dependency throughout the build system, but inconsistently so -- several parts of the CMake dependencies were missing and only showed up due to transitive deps or the fact that the target wasn't being built by tho bots. It turns out that the Comments library can't (currently) be a well formed layer *below* the AST library either, as it has an API that accepts an ASTContext. That parameter is currently unused, so maybe that was a mistake? Anyways, it really seems like this is logically part of the AST -- that's the whole point of the ASTContext providing access to it as far as I can tell -- so I've merged it into the AST library to solve the immediate layering violation problems and remove some of the churn from our library dependencies. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@158807 91177308-0d34-0410-b5e6-96231b3b80d8
2012-06-20Restructure how the driver communicates information about theJohn McCall
target Objective-C runtime down to the frontend: break this down into a single target runtime kind and version, and compute all the relevant information from that. This makes it relatively painless to add support for new runtimes to the compiler. Make the new -cc1 flag, -fobjc-runtime=blah-x.y.z, available at the driver level as a better and more general alternative to -fgnu-runtime and -fnext-runtime. This new concept of an Objective-C runtime also encompasses what we were previously separating out as the "Objective-C ABI", so fragile vs. non-fragile runtimes are now really modelled as different kinds of runtime, paving the way for better overall differentiation. As a sort of special case, continue to accept the -cc1 flag -fobjc-runtime-has-weak, as a sop to PLCompatibilityWeak. I won't go so far as to say "no functionality change", even ignoring the new driver flag, but subtle changes in driver semantics are almost certainly not intended. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@158793 91177308-0d34-0410-b5e6-96231b3b80d8

2012-06-19Improve the specification of spellings in Attr.td.Sean Hunt
Note that this is mostly a structural patch that handles the change from the old spelling style to the new one. One consequence of this is that all AT_foo_bar enum values have changed to not be based off of the first spelling, but rather off of the class name, so they are now AT_FooBar and the like (a straw poll on IRC showed support for this). Apologies for code churn. Most attributes have GNU spellings as a temporary solution until everything else is sorted out (such as a Keyword spelling, which I intend to add if someone else doesn't beat me to it). This is definitely a WIP. I've also killed BaseCheckAttr since it was unused, and I had to go through every attribute anyway. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@158700 91177308-0d34-0410-b5e6-96231b3b80d8

2012-06-16[AST/libclang] Fix the selector locations that are reported for aArgyrios Kyrtzidis
method definition that has its '{' attached to the method name without a space. With a method like: -(id)meth{ ..... } the logic in ObjCMethodDecl that determined the selector locations got confused because it was initialized based on an end location for '{' but that end location changed to '}' after the method was finished. Fix this by having an immutable end location for the declarator and for getLocEnd() get the end location from the body itself.

2012-06-10Remove CXXRecordDecl flags which are unused after r158289.Richard Smith
We need an efficient mechanism to determine whether a defaulted default constructor is constexpr, in order to determine whether a class is a literal type, so keep the incrementally-built form on CXXRecordDecl. Remove the on-demand computation of same, so that we only have one method for determining whether a default constructor is constexpr. This doesn't affect correctness, since default constructor lookup is much simpler than selecting a constructor for copying or moving. We don't need a corresponding mechanism for defaulted copy or move constructors, since they can't affect whether a type is a literal type. Conversely, checking whether such functions are constexpr can require non-trivial effort, so we defer such checks until the copy or move constructor is required. Thus we now only compute whether a copy or move constructor is constexpr on demand, and only compute whether a default constructor is constexpr in advance. This is unfortunate, but seems like the best solution. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@158290 91177308-0d34-0410-b5e6-96231b3b80d8
