* MS ABI: Don't use the Itanium scheme for numbering lambdasDavid Majnemer2014-08-224-48/+45
| | | | | | | | | | | The Itanium ABI will give out the same mangling number for two different lambdas if their call operators have different types. The MS ABI cannot do the same because it does not mangle the return type into it's lambdas. This fixes PR20719. llvm-svn: 216259

* CGCall: Factor out the logic mapping call arguments to LLVM IR arguments.Alexey Samsonov2014-08-222-235/+323
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Summary: This refactoring introduces ClangToLLVMArgMapping class, which encapsulates the information about the order in which function arguments listed in CGFunctionInfo should be passed to actual LLVM IR function, such as: 1) positions of sret, if there is any 2) position of inalloca argument, if there is any 3) position of helper padding argument for each call argument 4) positions of regular argument (there can be many if it's expanded). Simplify several related methods (ConstructAttributeList, EmitFunctionProlog and EmitCall): now they don't have to maintain iterators over the list of LLVM IR function arguments, dealing with all the sret/inalloca/this complexities, and just use expected positions of LLVM IR arguments stored in ClangToLLVMArgMapping. This may increase the running time of EmitFunctionProlog, as we have to traverse expandable arguments twice, but in further refactoring we will be able to speed up EmitCall by passing already calculated CallArgsToIRArgsMapping to ConstructAttributeList, thus avoiding traversing expandable argument there. No functionality change.

* Pass expressions instead of argument ranges to EmitCall/EmitCXXConstructorCall.Alexey Samsonov2014-08-216-64/+41
| | | | | | | | | | | | | | | | | | | | | | | Summary: This is a first small step towards passing generic "Expr" instead of ArgBeg/ArgEnd pair into EmitCallArgs() family of methods. Having "Expr" will allow us to get the corresponding FunctionDecl and its ParmVarDecls, thus allowing us to alter CodeGen depending on the function/parameter attributes. No functionality change.

* MS ABI: Don't always instantiate all members of dllexported class templates ↵Hans Wennborg2014-08-211-1/+11
| | | | | | | | | | | | | | | | (PR20163) Normally we mark all members of exported classes referenced to get them emitted. However, MSVC doesn't do this for class templates that are implicitly specialized or just have an explicit instantiation declaration. For such specializations, the members are emitted when referenced. The exception is the case when the dllexport attribute is propagated from a base class to a base class template that doesn't have an explicit attribute: in this case all methods of the base class template do get instantiated. llvm-svn: 216145

* Update link strategy for sanitizer runtime libraries on Linux:Alexey Samsonov2014-08-181-26/+33
| | | | | | | | | | | | | | | | | | | 1. Always put static sanitizer runtimes to the front of the linker invocation line. This was already done for all sanitizers except UBSan: in case user provides static libstdc++ we need to make sure that new/delete operator definitions are picked from sanitizer runtimes instead of libstdc++. We have to put UBSan runtime first for similar reasons: it depends on some libstdc++ parts (e.g. __dynamic_cast function), and has to go first in link line to ensure these functions will be picked up from libstdc++. 2. Put sanitizer libraries system dependencies (-ldl, -lpthread etc.) right after sanitizer runtimes. This will ensure these libraries participate in the link even if user provided -Wl,-as-needed flag. This should fix PR15823. 3. In case we link in several sanitizer runtimes (e.g. "ubsan", "ubsan_cxx" and "san"), add system dependencies (-ldl, -lpthread, ...) only once. llvm-svn: 215940
* Fix the rececl chain for redeclarations of predefined declsBen Langmuir2014-08-181-0/+2
| | | | | | | | | Predefined decls like 'Protocol' in objc are not loaded from AST files, so we cannot rely on loading the canonical decl to complete the redecl chain for redeclarations of these decls. The broken redecl chain was non-circular, so looping over redecls() would hang. llvm-svn: 215929

This fixes a crash + malformed AST file seen when loading some modules that import Cocoa on Darwin, which is a module with no contents except imports of other modules. Unfortunately I have not been able to find a reduced test case that reproduces this problem. Also add an assert that we aren't mapping one key to multiple values in CRM. We ought to be able to say there are no duplicate keys at all, but there are a bunch of 0 -> 0 mappings that are showing up, probably coming from the source location table. llvm-svn: 215810
* Make sure that vtables referenced from delay-parsed templates get referenced.Nico Weber2014-08-151-12/+15
| | | | | | | | | | | | | | This fixes PR20671, see the bug for details. In short, ActOnTranslationUnit() calls DefineUsedVTables() and only then PerformPendingInstantiations(). But PerformPendingInstantiations() is what does delayed template parsing, so vtables only references from late-parsed templates weren't marked used. As a fix, move the SavePendingInstantiationsAndVTableUsesRAII in PerformPendingInstantiations() up above the delayed template parsing code. That way, vtables referenced from templates end up in the RAII object, and the call to DefineUsedVTables() in PerformPendingInstantiations() marks them used. llvm-svn: 215786
