2010-09-12When performing overload resolution, only compare the final conversionDouglas Gregor
sequences for two conversion functions when in fact we are in the text of initialization by a user-defined conversion sequences. Fixes PR8034. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@113724 91177308-0d34-0410-b5e6-96231b3b80d8
2010-09-12Diagnose the instantiation of variables (including static dataDouglas Gregor
members) with function type. Fixes PR8047. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@113723 91177308-0d34-0410-b5e6-96231b3b80d8
2010-09-12Don't complain about useless user-defined conversion functions whenDouglas Gregor
they were instantiated from a template. In template metaprogramming, stuff happens. Fixes PR8065. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@113722 91177308-0d34-0410-b5e6-96231b3b80d8
2010-09-12When diagnosing C++ [temp.expl.spec]p3 in C++98/03 mode, downgrade theDouglas Gregor
error to a warning if we're in a case that would be allowed in C++0x. This "fixes" PR8084 by making Clang accept more code than GCC and (non-strict) EDG do. Also, add the missing test case for the C++0x semantics, which should have been in r113717. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@113718 91177308-0d34-0410-b5e6-96231b3b80d8
2010-09-12Implement C++0x semantics for [temp.expl.spec]p2, which loosens theDouglas Gregor
restrictions on out-of-line specializations to allow them anywhere in an enclosing context. Motivated by PR8084. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@113717 91177308-0d34-0410-b5e6-96231b3b80d8
2010-09-12Add basic support for Microsoft enum forward declaration. Francois Pichet
Assigning an underlying integral type to an enum forward declaration will come in a next patch. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@113716 91177308-0d34-0410-b5e6-96231b3b80d8
2010-09-12Implement the "note" in C++ [over.built]p1, which is actually meant toDouglas Gregor
be a semantic requirement that a built-in overloaded operator is not added to the overload set of there is already a user-defined overloaded operator with the same parameter types. Fixes PR8087. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@113713 91177308-0d34-0410-b5e6-96231b3b80d8
2010-09-12Don't perform integral promotions from an incompletion enumerationDouglas Gregor
type. Fixes PR8089 in a slightly different way than had been suggested. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@113711 91177308-0d34-0410-b5e6-96231b3b80d8
2010-09-11Teach the EvaluatedExprVisitor and its client, which marksDouglas Gregor
declarations in potentially-evaluated subexpressions, about recursion. Fixes the release-mode self-host failure I introduced in r113700. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@113708 91177308-0d34-0410-b5e6-96231b3b80d8

2010-09-11Update documentation to reflect the addition of support for in-classDouglas Gregor
initialization of static const floating-point data membmers (John's patch, in r113663). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@113701 91177308-0d34-0410-b5e6-96231b3b80d8
2010-09-11When parsing default function arguments, do not mark any declarationsDouglas Gregor
used in the default function argument as "used". Instead, when we actually use the default argument, make another pass over the expression to mark any used declarations as "used" at that point. This addresses two kinds of related problems: 1) We were marking some declarations "used" that shouldn't be, because we were marking them too eagerly. 2) We were failing to mark some declarations as "used" when we should, if the first time it was instantiated happened to be an unevaluated context, we wouldn't mark them again at a later point. I've also added a potentially-handy visitor class template EvaluatedExprVisitor, which only visits the potentially-evaluated subexpressions of an expression. I bet this would have been useful for noexcept... Fixes PR5810 and PR8127. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@113700 91177308-0d34-0410-b5e6-96231b3b80d8

2010-09-11The two libclang crash-recovery tests that involve precompiledDouglas Gregor
preambles end up leaving the precompiled preambles around. This is by design, since we do minimal cleanup during crash recovery. However, it's unfortunate for testing, so introduce a hook that allows these two tests to put the precompiled preamble somewhere where we can delete them after testing. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@113698 91177308-0d34-0410-b5e6-96231b3b80d8
2010-09-11If we fail to create a temporary file for the precompiled preamble,Douglas Gregor
just abort creation of the precompiled preamble rather than doing silly things. This is the second part of the fix for the weird preamble-related failures on Windows. Big thanks to Francois Pichet for the great detective work! git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@113697 91177308-0d34-0410-b5e6-96231b3b80d8

Windows GetTempPath() function, and be sure to create the directory in which the precompiled preamble will reside before creating the temporary file itself. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@113695 91177308-0d34-0410-b5e6-96231b3b80d8
