* block literal irgen: several improvements on naming blockFariborz Jahanian2012-06-265-9/+17
| | | | | | | | | | | | 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). llvm-svn: 159206

* Support the tls_model attribute (PR9788)Hans Wennborg2012-06-234-6/+32
| | | | | | | | | | | | | | This adds support for the tls_model attribute. This allows the user to choose a TLS model that is better than what LLVM would select by default. For example, a variable might be declared as: __thread int x __attribute__((tls_model("initial-exec"))); if it will not be used in a shared library that is dlopen'ed. This depends on LLVM r159077. llvm-svn: 159078

* Don't circumvent the debug info type cache when emitting info for ↵Benjamin Kramer2012-06-201-2/+3
| | | | | | | | | | | | EnumConstantDecl. CreateEnumType doesn't participate in caching so the descriptor for the enum gets recomputed for every reference of an element of an enum, only to get discarded when it gets turned into an MDNode. No functionality change except performance. llvm-svn: 158832

* Restructure how the driver communicates information about theJohn McCall2012-06-207-38/+87
| | | | | | | | | | | | | | | | | | | | | | | | 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

| | | | | | | | | option. On the driver, check if we are using libraries from gcc 4.7 or newer and if so pass -fuse-init-array to the frontend. The crtbegin*.o files in gcc 4.7 no longer call the constructors listed in .ctors, so we have to use .init_array. llvm-svn: 158694

| | | | | | | | | | semantics of a ctor/dtor function-try-block catch handler by pushing a normal cleanup is not just overkill but actually actively wrong when the handler contains an explicit return (which is only legal in a dtor). Just emit the rethrow as ordinary code at the fallthrough point. Fixes PR13102. llvm-svn: 158488
* More doxygen/documentation cleanups.James Dennett2012-06-131-5/+5
| | | | | | | | | | | | | | | | | | This reduces the number of warnings generated by Doxygen by about 100 (roughly 10%). Issues addressed: (1) Primarily, backslash-escaped "@foo" and "#bah" in Doxygen comments when they're not supposed to be Doxygen commands or links, and similarly for "<baz>" when it's not intended as as HTML tag; (2) Changed some \t commands (which don't exist) to \c ("to refer to a word of code", as the Doxygen manual says); (3) \precondition becomes \pre; (4) When touching comments, deleted a couple of spurious spaces in them; (5) Changed some \n and \r to \\n and \\r; (6) Fixed one tiny typo: #pragms -> #pragma. This patch touches documentation/comments only. llvm-svn: 158422

* [C++11 Compat] Fix breaking change in C++11 pair copyctor.Michael J. Spencer2012-06-081-2/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | While this code is valid C++98, it is not valid C++11. The problem can be reduced to: class MDNode; class DIType { operator MDNode*() const {return 0;} }; class WeakVH { WeakVH(MDNode*) {} }; int main() { DIType di; std::pair<void*, WeakVH> p(std::make_pair((void*)0, di))); } This was not detected by any of the bots we have because they either compile C++98 with libstdc++ (which allows it), or C++11 with libc++ (which incorrectly allows it). I ran into the problem when compiling with VS 2012 RC. Thanks to Richard for explaining the issue. llvm-svn: 158245

* Plug a long standing memory leak in TemplateArgument.Benjamin Kramer2012-06-071-1/+1
| | | | | | | | | | | | | | | The integral APSInt value is now stored in a decomposed form and the backing store for large values is allocated via the ASTContext. This way its not leaked as TemplateArguments are never destructed when they are allocated in the ASTContext. Since the integral data is immutable it is now shared between instances, making copying TemplateArguments a trivial operation. Currently getting the integral data out of a TemplateArgument requires creating a new APSInt object. This is cheap when the value is small but can be expensive if it's not. If this turns out to be an issue a more efficient accessor could be added. llvm-svn: 158150

| | | | | | | | | | | | | | 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.
