* PR16091: Error when attempting to emit debug info for undeduced auto return ↵David Blaikie2013-05-241-2/+7
| | | | | | | | | | | | types Perhaps we should just suppress this, rather than erroring, but since we have the infrastructure for it I figured I'd use it - if this is determined to be not the right thing we should probably remove that infrastructure entirely. I guess it's lying around from the early days of implementing debug info support. llvm-svn: 182673
* [PATCH] Generate cold attribute for functions marked __atribute__((cold))Diego Novillo2013-05-241-2/+3
| | | | | | | | | | | | | This removes a FIXME in CodeGenModule::SetLLVMFunctionAttributesForDefinition. When a function is declared cold we can now generate the IR attribute in addition to marking the function to be optimized for size. I tried adding a separate CHECK in the existing test, but it was failing. I suppose CHECK matches one line exactly once? This would be a problem if the attributes are listed in a different order, though they seem to be sorted. llvm-svn: 182666

* Implement __declspec(selectany) under -fms-extensionsReid Kleckner2013-05-201-1/+7
| | | | | | | | | | | | | | | | selectany only applies to externally visible global variables. It has the effect of making the data weak_odr. The MSDN docs suggest that unused definitions can only be dropped at linktime, so Clang uses weak instead of linkonce. MSVC optimizes away references to constant selectany data, so it must assume that there is only one definition, hence weak_odr.

* Revert "Revert "Debug Info: Using declarations/DW_TAG_imported_declaration ↵David Blaikie2013-05-203-11/+74
| | | | | | | | | | | | | | | | | | | | | of variables, types, and functions."" This reverts commit r181947 (git d2990ce56a16050cac0d7937ec9919ff54c6df62 ) This addresses one of the two issues identified in r181947, ensuring that types imported via using declarations only result in a declaration being emitted for the type, not a definition. The second issue (emitting using declarations that are unused) is hopefully an acceptable increase as the real fix for this would be a bit difficult (probably at best we could record which using directives were involved in lookups - but may not have been the result of the lookup). This also ensures that DW_TAG_imported_declarations (& directives) are not emitted in line-tables-only mode as well as ensuring that typedefs only require/emit declarations (rather than definitions) for referenced types. llvm-svn: 182231

| | | | | | | | | | | | | variables, types, and functions." This reverts commit r181393 (git 3923d6a87fe7b2c91cc4a7dbd90c4ec7e2316bcd). This seems to be emitting too much extra debug info for two (known) reasons: * full class definitions are emitted when only declarations are expected * unused using declarations still produce DW_TAG_imported_declarations llvm-svn: 181947
* Use only explicit bool conversion operatorDavid Blaikie2013-05-151-1/+1
| | | | | | | | | | | | | | | | | | | The most common (non-buggy) case are where such objects are used as return expressions in bool-returning functions or as boolean function arguments. In those cases I've used (& added if necessary) a named function to provide the equivalent (or sometimes negative, depending on convenient wording) test. DiagnosticBuilder kept its implicit conversion operator owing to the prevalent use of it in return statements. One bug was found in ExprConstant.cpp involving a comparison of two PointerUnions (PointerUnion did not previously have an operator==, so instead both operands were converted to bool & then compared). A test is included in test/SemaCXX/constant-expression-cxx1y.cpp for the fix (adding operator== to PointerUnion in LLVM). llvm-svn: 181869

* Cleanup handling of UniqueExternalLinkage.Rafael Espindola2013-05-133-4/+3
| | | | | | | | | | | | | This patch renames getLinkage to getLinkageInternal. Only code that needs to handle UniqueExternalLinkage specially should call this. Linkage, as defined in the c++ standard, is provided by getFormalLinkage. It maps UniqueExternalLinkage to ExternalLinkage. Most places in the compiler actually want isExternallyVisible, which handles UniqueExternalLinkage as internal. llvm-svn: 181677

Simple constant integer values for member pointers (offset within the object) and address for the value pointer case. GCC doesn't provide a value for the member function pointer case so I'm not sure how, if at all, GDB supports encoding that. & non-member function pointers should follow shortly in a subsequent patch. * Null pointer value encodings of all of these types, including correctly encoding null data member pointers as -1. llvm-svn: 181634

* [ms-cxxabi] Implement member pointer conversionsReid Kleckner2013-05-094-35/+314
| | | | | | | | | | | | | | | | | | | | | | | | | | Summary: This only supports converting along non-virtual inheritance paths by changing the field offset or the non-virtual base adjustment. This implements three kinds of conversions: - codegen for Value conversions - Constant emission for APValue - Constant folding for CastExprs In almost all constant initialization settings EmitMemberPointer(APValue) is called, except when the expression contains a reinterpret cast. reinterpret casts end up being a big corner case because the null value changes between different kinds of member pointers.

* Debug Info: Remove unnecessary check for dependent array typesDavid Blaikie2013-05-091-1/+1
| | | | | | | | | | This was added, untested (though the relevant crash was tested), in r128725/PR9600. Removing it doesn't cause failures & nothing I can imagine could cause this check to ever return 'true' (we should never be dealing with dependent types here). The subsequent change to check "isIncompleteType" (r128855/PR9608) makes a lot more sense. llvm-svn: 181542
* CodeGen for CapturedStmtsBen Langmuir2013-05-094-8/+171
| | | | | | | | | | | | | | | | | EmitCapturedStmt creates a captured struct containing all of the captured variables, and then emits a call to the outlined function. This is similar in principle to EmitBlockLiteral. GenerateCapturedFunction actually produces the outlined function. It is based on GenerateBlockFunction, but is much simpler. The function type is determined by the parameters that are in the CapturedDecl. Some changes have been added to this patch that were reviewed as part of the serialization patch and moving the parameters to the captured decl.

* Forward #pragma comment(lib/linker) through as flags metadataReid Kleckner2013-05-086-17/+92
| | | | | | | | | | | | | | | | | | | | | | Summary: Most of this change is wiring the pragma all the way through from the lexer, parser, and sema to codegen. I considered adding a Decl AST node for this, but it seemed too heavyweight. Mach-O already uses a metadata flag called "Linker Options" to do this kind of auto-linking. This change follows that pattern. LLVM knows how to forward the "Linker Options" metadata into the COFF .drectve section where these flags belong. ELF support is not implemented, but possible. This is related to auto-linking, which is http://llvm.org/PR13016. CC: cfe-commits Differential Revision: http://llvm-reviews.chandlerc.com/D723 llvm-svn: 181426
