Language-design credit goes to a lot of people, but I particularly want
to single out Blaine Garst and Patrick Beard for their contributions.

Compiler implementation credit goes to Argyrios, Doug, Fariborz, and myself,
in no particular order.

Douglas Gregor 6ab2fa8f78 Introduce Type::isSignedIntegerOrEnumerationType() and
Type::isUnsignedIntegerOrEnumerationType(), which are like
Type::isSignedIntegerType() and Type::isUnsignedIntegerType() but also
consider the underlying type of a C++0x scoped enumeration type.

Audited all callers to the existing functions, switching those that
need to also handle scoped enumeration types (e.g., those that deal
with constant values) over to the new functions. Fixes PR9923 /
<rdar://problem/9447851>.

Argyrios Kyrtzidis b2ed28ea4b For
double data[20000000] = {0};

we would blow out the memory by creating 20M Exprs to fill out the initializer.

To fix this, if the initializer list initializes an array with more elements than
there are initializers in the list, have InitListExpr store a single 'ArrayFiller' expression
that specifies an expression to be used for value initialization of the rest of the elements.

Fixes rdar://9275920.

Peter Collingbourne 9114759641 C1X: implement generic selections
As an extension, generic selection support has been added for all
supported languages.  The syntax is the same as for C1X.

John McCall 2979fe01da After some discussion with Doug, we decided that it made a lot more sense
for __unknown_anytype resolution to destructively modify the AST.  So that's
what it does now, which significantly simplifies some of the implementation.
Normal member calls work pretty cleanly now, and I added support for
propagating unknown-ness through &.

Anders Carlsson 8a01a751c9 Remove CK_DynamicToNull.
llvm-svn: 129265
2011-04-11 02:03:26 +00:00
Anders Carlsson c602006638 As a first step towards fixing PR9641, add a CK_DynamicToNull cast kind which
represents a dynamic cast where we know that the result is always null.

For example:

struct A {
  virtual ~A();
};
struct B final : A { };
struct C { };

bool f(B* b) {
  return dynamic_cast<C*>(b);
}

John McCall 319963434c Basic, untested implementation for an "unknown any" type requested by LLDB.
The idea is that you can create a VarDecl with an unknown type, or a
FunctionDecl with an unknown return type, and it will still be valid to
access that object as long as you explicitly cast it at every use.  I'm
still going back and forth about how I want to test this effectively, but
I wanted to go ahead and provide a skeletal implementation for the LLDB
folks' benefit and because it also improves some diagnostic goodness for
placeholder expressions.

Peter Collingbourne 599cb8e430 Add support for language-specific address spaces. On top of that,
add support for the OpenCL __private, __local, __constant and
__global address spaces, as well as the __read_only, _read_write and
__write_only image access specifiers.  Patch originally by ARM;
language-specific address space support by myself.

Ken Dyck 1c80fd1346 Introduce a CharUnits FieldOffsetInChars variable in AppendField() to
replace some uses of FieldOffsetInBytes. The remaining uses of
FieldOffsetInBytes will be replaced once NextFieldOffsetInBytes is converted
to CharUnits. No change in functionality intended.
