Devang Patel e67eca43d6 We need pointer size in bits here.

Argyrios Kyrtzidis ae40e4e10e Gcc pads the size of an array using the alignment of its elements. 
The size of the array may not be aligned according to alignment of its elements if an alignment attribute is
specified in a typedef. Fixes rdar://8665729 & http://llvm.org/PR5637.

John McCall 0009fcc39e Make yet another placeholder type, this one marking that an expression is a bound 
member function, i.e. something of the form 'x.f' where 'f' is a non-static
member function.  Diagnose this in the general case.  Some of the new diagnostics
are probably worse than the old ones, but we now get this right much more
universally, and there's certainly room for improvement in the diagnostics.

Chris Lattner f03406f103 don't use compound literals in MM macros, since they will be instantiated 
into user code which may warn about them with -pedantic.  Patch by Jonathan Sauer!

Chris Lattner cdb591af03 fix PR9474, a crash with -fshort-enum and C++ templates: when instantiating 
the enum decl, we need to use an integer type the same size as the enumerator,
which may not be the promoted type with packed enums.

Douglas Gregor b90f5185b6 When Sema::ClassifyName() finds an invalid ivar reference, return an 
invalid expression rather than the far-more-generic "error". Fixes a
mild regression in error recovery uncovered by the GCC testsuite.

Patch authored by David Abrahams.

These two expression traits (__is_lvalue_expr, __is_rvalue_expr) are used for
parsing code that employs certain features of the Embarcadero C++ compiler.

Sebastian Redl fa1f370b7d Fix adding an anonymous namespace in a chained PCH to a namespace from a previous PCH. 
Fix anonymous namespaces in PCH.

Sebastian Redl ab238a7d18 Synthesizing the definition of an implicit member is an AST modification, so notify any mutation listeners of it. This fixes a crasher in chained PCH, where an implicit destructor in a PCH gets a definition in a chained PCH, which is then lost. However, any further use of the destructor would cause its definition to be regenerated in the final file, hiding the bug. 
llvm-svn: 130103

Sebastian Redl f830df4e9d On reading DeclContexts from PCH, check for visible updates even if the context was empty in the original version. Also, if there are any, tell the context that it has external visible decls. This fixes the problem that a namespace that was empty in the initial PCH (could also happen if the initial PCH didn't include any std header but caused implicit creation of namespace std, e.g. due to implicit declaration of a virtual destructor) never found any declaration declared in *any* chained PCH. Very ugly when the chained PCH includes all that std stuff, as the errors were effectively the same as not including std headers.

Sebastian Redl 83f3b859ab Make the invalid declarator recovery when parsing members work the same as when parsing global decls. It's still rather broken (skipping much too far when the declarator belongs to a function definition), but at least not so broken as to mismatch braces. Tested by the removal of the fixme in the template test case. 
llvm-svn: 130101
 2011-04-24 16:27:48 +00:00
Sebastian Redl 14afaf0093 Store the full list of pending instantiations in a chained PCH. Previously we attempted to store only new pending instantiations, but our filter was incorrect, dropping implicit instantiations of class template members. It's just not worth coming up with a complex filter that is correct, when the only cost is PCH files that are a few hundred bytes (at most) larger.

Francois Pichet dd876125df Downgrade unnecessary "typename" from error to warning in Microsoft mode. 
This fixes 1 error when parsing MSVC 2008 headers with clang. 

Must "return true;" even if it is a warning because the rest of the code path assumes that SS is set to something. The parser will get back on its feet and continue parsing the rest of the declaration correctly so it is not a problem.

John McCall 617339e692 GCC seems to create address-of expression manglings when passing *any* 
function as a template argument where a pointer to function is wanted.

John McCall 6dc0a2b467 Update the mangler for some of the "new" unresolved-name manglings. 
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.
