2012-11-14Provide the correct mangling and linkage for certain unnamed nested classes.David Blaikie
This corrects the mangling and linkage of classes (& their member functions) in cases like this: struct foo { struct { void func() { ... } } x; }; we were accidentally giving this nested unnamed struct 'no' linkage where it should've had the linkage of the outer class. The mangling was incorrecty too, mangling as TU-wide unnamed type mangling of $_X rather than class-scoped mangling of UtX_. This also fixes -Wunused-member-function which would incorrectly diagnose 'func' as unused due to it having no linkage & thus appearing to be TU-local when in fact it might be correctly used in another TU. Similar mangling should be applied to function local classes in similar cases but I've deferred that for a subsequent patch.

mangling of floating-point literals.

2012-01-18constexpr: converted constant expression handling for enumerator values, caseRichard Smith
values and non-type template arguments of integral and enumeration types. This change causes some legal C++98 code to no longer compile in C++11 mode, by enforcing the C++11 rule that narrowing integral conversions are not permitted in the final implicit conversion sequence for the above cases. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@148439 91177308-0d34-0410-b5e6-96231b3b80d8

2011-07-12Improve name mangling for instantiation-dependent types that are notDouglas Gregor
dependent. This covers an odd class of types such as int (&)[sizeof(sizeof(T() + T()))]; which involve template parameters but, because of some trick typically involving a form of expression that is never type-dependent, resolve down to a non-dependent type. Such types need to be mangled essentially as they were written in the source code (involving template parameters), rather than via their canonical type. In general, instantiation-dependent types should be mangled as they were written in the source. However, since we can't do that now without non-trivial refactoring of the AST (see the new FIXME), I've gone for this partial solution: only use the as-written-in-the-source mangling for these strange types that are instantiation-dependent but not dependent. This provides better compatibility with previous incarnations of Clang and with GCC. In the future, we'd like to get this right. Fixes <rdar://problem/9663282>. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@134984 91177308-0d34-0410-b5e6-96231b3b80d8

2011-07-01Just mangle substituted template parameter types as unresolved types.John McCall
This is kindof questionable but seems to do more-or-less the right thing. This is not a particularly friendly part of the ABI. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@134227 91177308-0d34-0410-b5e6-96231b3b80d8
2011-07-01Introduce the notion of instantiation dependence into Clang's AST. ADouglas Gregor
type/expression/template argument/etc. is instantiation-dependent if it somehow involves a template parameter, even if it doesn't meet the requirements for the more common kinds of dependence (dependent type, type-dependent expression, value-dependent expression). When we see an instantiation-dependent type, we know we always need to perform substitution into that instantiation-dependent type. This keeps us from short-circuiting evaluation in places where we shouldn't, and lets us properly implement C++0x [temp.type]p2. In theory, this would also allow us to properly mangle instantiation-dependent-but-not-dependent decltype types per the Itanium C++ ABI, but we aren't quite there because we still mangle based on the canonical type in cases like, e.g., template<unsigned> struct A { }; template<typename T> void f(A<sizeof(sizeof(decltype(T() + T())))>) { } template void f<int>(A<sizeof(sizeof(int))>); and therefore get the wrong answer. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@134225 91177308-0d34-0410-b5e6-96231b3b80d8

2011-05-04Type prefixes of unresolved-names should only be mangled as unresolved-typesJohn McCall
if they match that production, i.e. if they're template type parameters or decltypes (or, as an obvious case not yet described in the ABI document, if they're template template parameters applied to template arguments). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@130824 91177308-0d34-0410-b5e6-96231b3b80d8

Patch authored by John Wiegley. These type traits are used for parsing code that employs certain features of the Embarcadero C++ compiler. Several of these constructs are also desired by libc++, according to its project pages (such as __is_standard_layout). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@130342 91177308-0d34-0410-b5e6-96231b3b80d8

2011-04-24Update the mangler for some of the "new" unresolved-name manglings.John McCall
I've sent off an email requesting clarification on a few things that I wasn't sure how to handle. This also necessitated making prefixes and unresolved-prefixes get mangled separately. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@130083 91177308-0d34-0410-b5e6-96231b3b80d8
2011-04-24The ABI settled on mangling float literals with lowercase hex dumps.John McCall
APInt::toString doesn't do those, but it's easy to postprocess that output, and that's probably better than adding another knob to that method. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@130081 91177308-0d34-0410-b5e6-96231b3b80d8
2011-03-22File-scope static functions need to be mangled with 'L' so thatJohn McCall
they don't collide with file-scope extern functions from the same translation unit. This is basically a matter of applying the same logic to FunctionDecls as we were previously applying to VarDecls. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@128072 91177308-0d34-0410-b5e6-96231b3b80d8
