John McCall 32f44bd0fc Ignore indirect field declarations. Fixes PR9570. 
llvm-svn: 129337
 2011-04-12 01:01:22 +00:00
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 0c63350b0b If there's an invoke destination, we should use invoke instead of call when calling the __cxa_bad_typeid function. Fixes PR7400.

Anders Carlsson 8a01a751c9 Remove CK_DynamicToNull. 
llvm-svn: 129265
 2011-04-11 02:03:26 +00:00
Anders Carlsson c1c9971cab When we know that a dynamic_cast always returns null, we can make 
CodeGenFunction::EmitDynamicCast always return null or throw a bad_cast 
exception.

llvm-svn: 129261
 2011-04-11 00:30:07 +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);
}

Eli Friedman 493c34a86c PR9580: Handle vectors correctly in ScalarExprEmitter::EmitRem. 
While I'm here, FileCheck-ize the ext-vector test, so we actually check
what it is generating.

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.

Andrew Trick 15e36e8edd Added *hidden* flags -print-options and -print-all-options so 
developers can see if their driver changed any cl::Option's. The
current implementation isn't perfect but handles most kinds of
options. This is nice to have when decomposing the stages of
compilation and moving between different drivers. It's also a good
sanity check when comparing results produced by different command line
invocations that are expected to produce the comparable results.

Note: This is not an attempt to prolong the life of cl::Option. On the
contrary, it's a placeholder for a feature that must exist when
cl::Option is replaced by a more appropriate framework. A new
framework needs: a central option registry, dynamic name lookup,
non-global containers of option values (e.g. per-module,
per-function), *and* the ability to print options values and their defaults at
any point during compilation.
