Fariborz Jahanian 9b5528d278 Patch to correctly mangle block helper functions 
when block literal is declared inside a ctor/dtor.
Fixes radr 8096995.

 2010-06-24 00:08:06 +00:00
Fariborz Jahanian 3b83618054 Block Code Gen. API. Call destructor on descriptior 
entry previously constructed via copy constructor.

Fariborz Jahanian a2d7c34e93 Fixed a block regression caused by trying to use 
an existing ir for load of a bock variable. This cannot be
done across basic blocks.
Fixes radar 8064140.

Fariborz Jahanian ea882cd92e Build AST for copy-construction of copied-in 
class object in blocks and carry it to IRGen.

Fariborz Jahanian 64176c2c97 For C++ copied in objects, use copy constructors in 
setting up block's descriptor. This is on going work to
support c++ specific issues in setting up blocks
various APIs.

Douglas Gregor 02df9da2ac Fix compilation failure 
llvm-svn: 104613
 2010-05-25 17:12:30 +00:00
Douglas Gregor 7e10f3699a Improve name mangling for blocks and support mangling of static local 
variables within blocks. We loosely follow GCC's mangling, but since
these are always internal symbols the names don't really matter. I
intend to revisit block mangling later, because GCC's mangling is
rather verbose. <rdar://problem/8015719>.

John McCall 9d42f0f174 Allocate space in a block record for implicit references to the Objective C 
'self' variable arising from uses of the 'super' keyword.  Also reorganize
some code so that BlockInfo (now CGBlockInfo) can be opaque outside of
CGBlocks.cpp.

Fixes rdar://problem/8010633.

John McCall 87fe5d5618 Support implicitly closing on 'this' in a block. Fixed PR7165. 
(the codegen works here, too, but that's annoying to test without execution)

John McCall 4d4dcc8ed7 When synthesizing Objective C records, give the synthetic fields public 
access.  Fixes an assertion.

Fixes rdar://problem/7927811.  Too lazy to reduce a test case.

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.

Rafael Espindola c50c27cca8 the big refactoring bits of PR3782. 
This introduces FunctionType::ExtInfo to hold the calling convention and the
noreturn attribute. The next patch will extend it to include the regparm
attribute and fix the bug.

Blaine Garst f27ab71d9f add support for a 1<<29 bit in the block flags field to mark blocks using alternate struct return ABI 
llvm-svn: 97775
 2010-03-05 01:29:59 +00:00
Blaine Garst fc83aa04db Unconditionally support block introspection data in a new field at the end 
of the block descriptor field.  This field is the ObjC style @encode
signature of the implementation function, and was to this point
conditionally provided in the block literal data structure.  That
provisional support is removed.

Additionally, eliminate unused enumerations for the block literal flags field.
The first shipping ABI unconditionally set (1<<29) but this bit is unused
by the runtime, so the second ABI will unconditionally have (1<<30) set so
that the runtime can in fact distinguish whether the additional data is
present or not.

Fariborz Jahanian 999ddbcf8e Patch to remove arbitrary imporation of 'self' into 
a block without it being used. This causes over release
of objects in certain runtime-senitive apps.
(fixes radar 7581175).

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().

Ken Dyck 40775003e6 Roll out ASTContext::getTypeSizeInChars(), replacing instances of 
"ASTContext::getTypeSize() / 8". Replace [u]int64_t variables with CharUnits
ones as appropriate. 

Also rename RawType, fromRaw(), and getRaw() in CharUnits to QuantityType, 
fromQuantity(), and getQuantity() for clarity.
