* Restructure how the driver communicates information about theJohn McCall2012-06-201-2/+12
| | | | | | | | | | | | | | | | | | | | | | | | 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. llvm-svn: 158793

* Revert Decl's iterators back to pointer value_type rather than reference ↵David Blaikie2012-06-061-5/+5
| | | | | | | | | | | | | | value_type In addition, I've made the pointer and reference typedef 'void' rather than T* just so they can't get misused. I would've omitted them entirely but std::distance likes them to be there even if it doesn't use them. This rolls back r155808 and r155869. Review by Doug Gregor incorporating feedback from Chandler Carruth. llvm-svn: 158104
* Remove the ref/value inconsistency in filter_decl_iterator.David Blaikie2012-04-301-5/+8
| | | | | | | | | | | | | filter_decl_iterator had a weird mismatch where both op* and op-> returned T* making it difficult to generalize this filtering behavior into a reusable library of any kind. This change errs on the side of value, making op-> return T* and op* return T&. (reviewed by Richard Smith) llvm-svn: 155808

* Unify naming of LangOptions variable/get function across the Clang stack ↵David Blaikie2012-03-111-18/+18
| | | | | | | | | | (Lex to AST). The member variable is always "LangOpts" and the member function is always "getLangOpts". Reviewed by Chris Lattner llvm-svn: 152536
* Add clang support for new Objective-C literal syntax for NSDictionary, NSArray,Ted Kremenek2012-03-061-1/+52
| | | | | | | | | | | | | NSNumber, and boolean literals. This includes both Sema and Codegen support. Included is also support for new Objective-C container subscripting. My apologies for the large patch. It was very difficult to break apart. The patch introduces changes to the driver as well to cause clang to link in additional runtime support when needed to support the new language features. Docs are forthcoming to document the implementation and behavior of these features. llvm-svn: 152137

* Whether an argument is required (in contrast with being anJohn McCall2012-02-171-36/+26
| | | | | | | | | | | | | | | | | | | | | optional argument passed through the variadic ellipsis) potentially affects how we need to lower it. Propagate this information down to the various getFunctionInfo(...) overloads on CodeGenTypes. Furthermore, rename those overloads to clarify their distinct purposes, and make sure we're calling the right one in the right place. This has a nice side-effect of making it easier to construct a function type, since the 'variadic' bit is no longer separable. This shouldn't really change anything for our existing platforms, with one minor exception --- we should now call variadic ObjC methods with the ... in the "right place" (see the test case), which I guess matters for anyone running GNUStep on MIPS. Mostly it's just a substantial clean-up. llvm-svn: 150788
* Use the new method for specifying garbage collection metadata in the module.Bill Wendling2012-02-161-25/+40
| | | | | | | | | | The garbage collection metadata needs to be merged "intelligently", when two or more modules are linked together, and not merely appended. (Appending creates a section which is too large.) The module flags metadata method is the way to do this. <rdar://problem/8198537> llvm-svn: 150648

| | | | | | | | | | | | | | | | | commit 149470. This fixes test/CodeGen/PR3589-freestanding-libcalls.c. Original log: ConstantArray::get() (for strings) is going away, use ConstantDataArray::getString instead. Many instances of ConstantArray::get() could be moved to use more efficient ConstantDataArray methods that avoid a ton of intermediate Constant*'s for each element (e.g. GetConstantArrayFromStringLiteral).

However, note that we're not taking advantage of much of this code yet, because we're still re-using ObjCProtocolDecls. llvm-svn: 147410

The same is done for property @encode already. 2. Each block object is marked with its function prototype's @encoding. For example, a method parameter that is a block object that itself returns void and takes an int would look like: @?<v@?i> These new method @encode strings are stored in a single array pointed to by structs protocol_t and objc_protocol_ext.
