| | | | | | | | | features needed for a particular module to be available. This allows mixed-language modules, where certain headers only work under some language variants (e.g., in C++, std.tuple might only be available in C++11 mode). llvm-svn: 147387

| | | | | | | | | | | | Also temporarily remove the assumption from IR gen that we can emit IR for every constant we can fold, since it isn't currently true in C++11, to fix PR11676. Original comment from r147271: constexpr: perform zero-initialization prior to / instead of performing a constructor call when appropriate. Thanks to Eli for spotting this. llvm-svn: 147384

* Change the diagnostics which said 'accepted as an extension' to instead sayRichard Smith2011-12-2918-50/+49
| | | | | | | 'is an extension'. The former is inappropriate and confusing when building with -Werror/-pedantic-errors. llvm-svn: 147357

* Add a target hook for FLT_EVAL_METHOD and use it to set the value on x86 ↵Benjamin Kramer2011-12-281-2/+2
| | | | | | | | | with sse disabled. x87 math evaluates everything with 80 bits precision, so we have to set FLT_EVAL_METHOD to "2". llvm-svn: 147311
* Support the 'a' scanf length modifier as an extension in C++.Hans Wennborg2011-12-282-0/+28
| | | | | | | It should not be supported in C++11, since that uses the C99 standard library, in which 'a' is a format specifier. llvm-svn: 147310
* Eliminate ObjCClassDecl, which is redundant now that ObjCInterfaceDeclDouglas Gregor2011-12-275-5/+6

* Fix several issues related to specializations and explicit instantiations.Nico Weber2011-12-231-0/+128
| | | | | | | | | | | | | | | Explicit instantiations following specializations are no-ops and hence have no PointOfInstantiation. That was done correctly in most cases, but for a specialization -> instantiation decl -> instantiation definition chain, the definition didn't realize that it was a no-op. Fix that. Also, when printing diagnostics for these no-ops, get the diag location from the decl name location. Add many test cases, one of them not yet passing (but it failed the same way before this change). Fixes http://llvm.org/pr11558 and more. llvm-svn: 147225

* Serialize the AST reader's mapping from canonical declarations to theDouglas Gregor2011-12-223-1/+10
| | | | | | | | | | | | | | | | set of (previously-canonical) declaration IDs to the module file, so that future AST reader instances that load the module know which declarations are merged. This is important in the fairly tricky case where a declaration of an entity, e.g., @class X; occurs before the import of a module that also declares that entity. We merge the declarations, and record the fact that the declaration of X loaded from the module was merged into the (now canonical) declaration of X that we parsed. llvm-svn: 147181

* When deserializing an Objective-C class, check whether we have anotherDouglas Gregor2011-12-223-0/+45
| | | | | | | | | | | | | | | | declaration of that same class that either came from some other module or occurred in the translation unit loading the module. In this case, we need to merge the two redeclaration chains immediately so that all such declarations have the same canonical declaration in the resulting AST (even though they don't in the module files we've imported). Focusing on Objective-C classes until I'm happy with the design, then I'll both (1) extend this notion to other kinds of declarations, and (2) optimize away this extra checking when we're not dealing with modules. For now, doing this checking for PCH files/preambles gives us better testing coverage. llvm-svn: 147123
