* CodeGen: Skip unnamed bitfields when handling designated initializersDavid Majnemer2014-08-231-1/+9

We previously had *no record* in the scope for class template declarations, once those declarations completed and their template parameter scopes were popped. This in turn caused us to be unable to merge class template declarations that were declared in the global scope (where we use scope lookup rather than DeclContext lookup for merging), when loading a module. llvm-svn: 216311

* Fix PR17239 by changing the semantics of the RemainingArgsClass Option kindReid Kleckner2014-08-221-2/+5
| | | | | | | | | | | | | | | | | | | | | | | This patch aims at fixing PR17239. This bug happens because the /link (clang-cl.exe argument) is marked as "consume all remaining arguments". However, when inside a response file, /link should only consume all remaining arguments inside the response file where it is located, not the entire command line after expansion. The LLVM side of the patch will change the semantics of the RemainingArgsClass kind to always consume only until the end of the response file when the option originally came from a response file. There are only two options in this class: dash dash (--) and /link. This is the Clang side of the patch in http://reviews.llvm.org/D4899 Reviewered By: rafael, rnk Differential Revision: http://reviews.llvm.org/D4900 Patch by Rafael Auler! llvm-svn: 216281

* Fixing MSVC warning: "warning C4373: 'blah': virtual function overrides ↵Aaron Ballman2014-08-221-4/+2
| | | | | | | | 'blah', previous versions of the compiler did not override when parameters only differed by const/volatile qualifiers." This warning is basically useless because the "previous versions" being referred to is MSVC 2005 and earlier, and we obviously do not care about them. However, this warning isn't particularly chatty (I don't recall ever seeing it previously), and it has the opportunity to point out cases where the cv-qualifiers differ unintentionally (like this case), so I am leaving it enabled for now. llvm-svn: 216267
* [AArch64, inline-asm] Improve diagnostic that is printed when the size of aAkira Hatanaka2014-08-223-15/+67
| | | | | | | | | | | | | | | | | variable that has regiser constraint "r" is not 64-bit. General register operands are output using 64-bit "x" register names, regardless of the size of the variable, unless the asm operand is prefixed with the "%w" modifier. This surprises and confuses many users who aren't familiar with aarch64 inline assembly rules. With this commit, a note and fixit hint are printed which tell the users that they need modifier "%w" in order to output a "w" register instead of an "x" register. <rdar://problem/12764785> llvm-svn: 216260
* 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
