Add RTTIBuilder::GetAddrOfTypeName which uses the newly added CreateOrReplaceCXXRuntimeVariable.

Set the visibility for typeinfo names.

llvm-svn: 124548

Change CodeGenModule::setTypeVisibility to take a TypeVisibilityKind enum instead of an "IsForRTTI" flag.

llvm-svn: 124546

Replace an isa/cast with a dyn_cast.

llvm-svn: 124542

Get rid of an unneeded parameter from setGlobalVisibility.

llvm-svn: 124541

Use CGM.CreateOrReplaceCXXRuntimeVariable in CGVTables.cpp

llvm-svn: 124538

Add a new function, to be used by CGRTTI, CGVTables and CGVTT (which each has their own copy of this code).

llvm-svn: 124537

Replace a literal '8' with getCharWidth().

llvm-svn: 124536

Remove IsDefinition from CodeGenModule::setTypeVisibility; it is always true.

llvm-svn: 124529

Mark VTables and RTTI data linkonce_odr instead of weak_odr, with the exception of explicit template instantiations, which have to be weak_odr.

This fixes PR6996.

llvm-svn: 124089

Use a FunctionType::get overload that doesn't require an empty vector.

llvm-svn: 124029

Add unnamed_addr in CreateRuntimeVariable.

llvm-svn: 123773

Replace calls to CharUnits::fromQuantity() with ones to
ASTContext::toCharUnitsFromBits() when converting from bit sizes to char units.

llvm-svn: 123720

More unnamed_addr.

llvm-svn: 123681

merge strings created by
const NSConstantString *appKey = @"MyApp";

llvm-svn: 123680

Add unnamed_addr to the special strings created by
__builtin___CFStringMakeConstantString
This fixes PR8993. A darwin expert might want to check that this is safe.

Move name mangling support from CodeGen to AST. In the
process, perform a number of refactorings:

- Move MiscNameMangler member functions to MangleContext
- Remove GlobalDecl dependency from MangleContext
- Make MangleContext abstract and move Itanium/Microsoft functionality
to their own classes/files
- Implement ASTContext::createMangleContext and have CodeGen use it

No (intended) functionality change.

Set unnamed_addr for type infos that we are confortable marking as hidden. I
think it is safe to mark all type infos with unnamed_addr, but I am not sure.

llvm-svn: 123275

Add unnamed_addr to constructors and destructors.

llvm-svn: 123197

Add unnamed_addr when creating artificial string globals. For example, in

static const char foo[] = "foo";
static const char *bar = "bar";

Add unnamed_addr when creating artificial string globals. For example, in

Set the "implicitly inline" bit on a method as soon as we see a definition
within the class. Teach IR gen to look for function definitions in record
lexical contexts when deciding whether to emit a function whose address
was taken. Fixes PR8789.

Simplify the logic for emitting guard variables for template static
data members by delaying the emission of the initializer until after
linkage and visibility have been set on the global. Also, don't
emit a guard unless the variable actually ends up with vague linkage,
and don't use thread-safe statics in any case.

Better solution: calculate the visibility of functions and variables
independently of whether they're definitions, then teach IR generation to
ignore non-explicit visibility when emitting declarations. Use this to
make sure that RTTI, vtables, and VTTs get the right visibility.
