John McCall 61d8258fa3 Roll back r104941.
llvm-svn: 104990
2010-05-28 18:25:28 +00:00
John McCall 2177a9b65a Add a new attribute on records, __attribute__((adl_invisible)), and define
the x86-64 __va_list_tag with this attribute.  The attribute causes the
affected type to behave like a fundamental type when considered by ADL.

(x86-64 is the only target we currently provide with a struct-based
__builtin_va_list)

Fixes PR6762.

Douglas Gregor c4df407604 Keep track of the actual storage specifier written on a variable or
function declaration, since it may end up being changed (e.g.,
"extern" can become "static" if a prior declaration was static). Patch
by Enea Zaffanella and Paolo Bolzoni.

Douglas Gregor b2ccf010fb Feed proper source-location information into Sema::LookupSingleResult,
in case it ends up doing something that might trigger diagnostics
(template instantiation, ambiguity reporting, access
reporting). Noticed while working on PR6831.

John McCall 3e11ebebc8 Remember declaration scope qualifiers in the AST. Imposes no memory overhead
on unqualified declarations.

Patch by Enea Zaffanella!  Minimal adjustments:  allocate the ExtInfo nodes
with the ASTContext and delete them during Destroy().  I audited a bunch of
Destroy methods at the same time, to ensure that the correct teardown was
being done.

Ted Kremenek 2fb89539f7 Clang really intends to reject attribute 'warn_unused_result' on Objective-C methods, but
instead it crashes on them.  We might extend this attribute to work on methods, but for
now fix the crasher.  Addresses <rdar://problem/7670939>.

Charles Davis 163855f46d dllimport and dllexport are declspec attributes, too. They're also
Win32-specific.

Also, fix a test to use FileCheck instead of grepping LLVM IR.

Ted Kremenek 510ee2594e Use the allocator associated with ASTContext to allocate the args
array associated with NonNullAttr.  This fixes yet another leak when
ASTContext uses a BumpPtrAllocator.

Ted Kremenek 7f4945aa9c Remove use of 'std::string' from Attr objects, using instead a byte
array allocated using the allocator in ASTContext.  This addresses
these strings getting leaked when using a BumpPtrAllocator (in
ASTContext).

John McCall ab26cfa58d Standardize the parsing of function type attributes in a way that
follows (as conservatively as possible) gcc's current behavior:  attributes
written on return types that don't apply there are applied to the function
instead, etc.  Only parse CC attributes as type attributes, not as decl attributes;
don't accepet noreturn as a decl attribute on ValueDecls, either (it still
needs to apply to other decls, like blocks).  Consistently consume CC/noreturn
information throughout codegen;  enforce this by removing their default values
in CodeGenTypes::getFunctionInfo().

Chandler Carruth 72343706c1 Correctly treat 64 bit integers specified via the mode attribute as the 'long'
type when that type is 64 bits wide, and the 'long long' type when 'long' is
only 32 bits wide. This fixes PR6108.

Also adds a bunch of test cases to ensure proper conversion between equally
sized standard types and mode-specified types on both 32 and 64 bit targets.

Mike Stump feb1945fee This patch should fix PR2461. It allows clang to apply the noreturn

pointers for the noreturn attribute when checking for fallthrough.

John McCall bcd035061d DeclaratorInfo -> TypeSourceInfo. Makes an effort to rename associated variables,

John McCall e66edc18ae Rip out TemplateIdRefExpr and make UnresolvedLookupExpr and
DependentScopeDeclRefExpr support storing templateids.  Unite the common   
code paths between ActOnDeclarationNameExpr and ActOnTemplateIdExpr.

This gets us to a point where we don't need to store function templates in
the AST using TemplateNames, which is critical to ripping out OverloadedFunction.

Also resolves a few FIXMEs.

Alexis Hunt 96d5c76498 Added rudimentary C++0x attribute support.
The following attributes are currently supported in C++0x attribute
lists (and in GNU ones as well):
 - align() - semantics believed to be conformant to n3000, except for
   redeclarations and what entities it may apply to
 - final - semantics believed to be conformant to CWG issue 817's proposed
   wording, except for redeclarations
 - noreturn - semantics believed to be conformant to n3000, except for
   redeclarations
 - carries_dependency - currently ignored (this is an optimization hint)
