John McCall 1c456c89dc Abstract out member-pointer creation. I'm really unhappy about the current 
duplication between the constant and non-constant paths in all of this.

Implement ARM ABI semantics for member pointer constants and conversion.

John McCall a8bbb82c55 Abstract out member-pointer conversions. 
Pretty much everything having to do with member pointers is ABI-specific.

John McCall 86353416a7 The ARM C++ ABI is sufficiently different from the Itanium C++ ABI that 
it deserves its own enumerator.  Obviously the implementations should
closely follow the Itanium ABI except in cases of divergence.

Daniel Dunbar b657ac51cf IRgen/CGValue: Add getQuals(), so qualifiers can be modified on an LValue.

Daniel Dunbar e50dda95ee IRgen/LValue: Add LValue::setNonGC instead of SetObjCNonGC, for consistency with isNonGC(). 
llvm-svn: 111718
 2010-08-21 03:22:38 +00:00
Daniel Dunbar 2e442a00b3 IRgen: Switch more MakeAddr() users to MakeAddrLValue; this time for calls which were previously not computing the qualifier list. In most cases, I don't think it matters, but I believe this is conservatively more correct / consistent.

Daniel Dunbar 93b00a98a3 IRgen: Add an LValue::MakeAddr variant which takes a type and uses that to build 
the qualifiers.

Also, add CodeGenFunction::MakeAddrLValue() helper function which passes in the
ASTContext.

Daniel Dunbar 0381634a61 IRgen: Change Emit{Load,Store}OfScalar to take a required Alignment argument and 
update callers as best I can.
 - This is a work in progress, our alignment handling is very horrible / sketchy -- I am just aiming for monotonic improvement.
 - Serious review appreciated.

Dan Gohman 196f71006e Introduce a new temporary MDNode concept. Temporary MDNodes are 
not part of the IR, are not uniqued, and may be safely RAUW'd.
This replaces a variety of alternate mechanisms for achieving
the same effect.

Douglas Gregor e3b3464d4e Fix a major regression with value-initialization of class types with 
trivial default constructors. We're weren't zero-initializing them,
which manifested as <rdar://problem/8320532> (a regression in the GCC
test suite) and is likely to have caused significant other breakage.

Charles Davis 6bcb07ad71 Add some enum goodness as requested by Chris. Now instead of storing the 
active C++ ABI as a raw string, we store it as an enum. This should improve
performance somewhat.

And yes, this time, I started from a clean build directory, and
all the tests passed. :)

Alexis Hunt dcfba7b35b Generate Attr subclasses with TableGen. 
Now all classes derived from Attr are generated from TableGen.
Additionally, Attr* is no longer its own linked list; SmallVectors or
Attr* are used. The accompanying LLVM commit contains the updates to
TableGen necessary for this.

Some other notes about newly-generated attribute classes:

 - The constructor arguments are a SourceLocation and a Context&,
   followed by the attributes arguments in the order that they were
   defined in Attr.td

 - Every argument in Attr.td has an appropriate accessor named getFoo,
   and there are sometimes a few extra ones (such as to get the length
   of a variadic argument).

Additionally, specific_attr_iterator has been introduced, which will
iterate over an AttrVec, but only over attributes of a certain type. It
can be accessed through either Decl::specific_attr_begin/end or
the global functions of the same name.

John McCall 78fbb61ed7 Contextual arity is a feature of mangling expressions; kill off 
mangleCallExpression.  Also, operator names with unknown arity should
be mangled as binary operators;  this is actually covered by an oddly-
positioned sentence in the ABI document.  Fixes PR7891.

John McCall b3732bb3b7 Just disable the hidden-visibility optimization for now by hiding it behind 
a -cc1 option.  The Darwin linker complains about mixed visibility when linking
gcc-built objects with clang-built objects, and the optimization isn't really
that valuable.  Platforms with less ornery linkers can feel free to enable this.
