Chris Lattner 6fb0ccfa0f Enhance the IR type lowering code to be much smarter about recursively lowering
types.  Fore xample, we used to lower:

struct bar { int a; };
struct foo {
 void (*FP)(struct bar);
} G;

to:

%struct.foo = type { {}* }

since the function pointer would cause recursive translation of bar and
we didn't know if that would get us into trouble.  We are now smart enough
to know that it is fine, so we get this type instead:

%struct.foo = type { void (i32)* }

Codegen still needs to be prepared for uncooperative types at any place,
which is why I let the maximally uncooperative code sit around for awhile to
help shake out the bugs.

John McCall 7c454bb8ce Create a new expression node, SubstNonTypeTemplateParmExpr,
to represent a fully-substituted non-type template parameter.
This should improve source fidelity, as well as being generically
useful for diagnostics and such.

Richard Trieu cfe3926ae9 Remove warnings of constant operands of logical operators from template instantiations. Upon instantiation of template, value-dependent parameters are replaced by equivalent literals, so code like:
template<unsigned int A, unsigned int B> struct S {
  int foo() {
    int x = A && B;
  }
}

will not warn on A && B on every instantiation.  This will still warn on other cases inside templates, which will be caught on checking the template definition.

Richard Smith 7b8c3c91f4 PR10359: Template declarations which define classes are not permitted to also contain declarators. Previously we would accept code like this:
template<typename T> struct S { } f() { return 0; }

This case now produces a missing ';' diagnostic, since that seems like a much more likely error than an attempt to declare a function or variable in addition to the class template.

Treat this

Argyrios Kyrtzidis 84b528f3b1 [arcmt] Emit an error for unused -autorelease messages.
An unused autorelease is badness. If we remove it the receiver
will likely die immediately while previously it was kept alive
by the autorelease pool. This is bad practice in general, so leave it
and emit an error to force the user to restructure his code.

Sebastian Redl 9c61809c23 For C++11, do more checking of initializer lists up-front, enabling some subset of the final functionality. C just leaves the function early. C++98 runs through the same code path, but has no changed functionality either.
This is a first baby step towards supporting generalized initializer lists. This also removes an aggregate
test case that was just plain wrong, assuming that non-aggregates couldn't be initialized with initializer lists
in C++11 mode.

Chandler Carruth 6d900dff2d Clean up some comments I missed when switching from
NestedMacroInstantiations -> NestedMacroExpansions.

those APIs.

Chandler Carruth de81fc8557 NestedMacroInstantiations -> NestedMacroExpansions
This is switches all the interfaces points (and most of the commenst
/ local variables I saw on my way through) regarding the
NestedMacroInstantiations bit.

The libclang enums corresponding to this state were renamed, but
a legacy enum was added with the old name, and the same value to keep
existing clients working. I've added a documentation blurb for it, but
let me know if there is a canonical way to document legacy elemenst of
the libclang interface.

No functionality changed here, even in tests.

Chandler Carruth 9e4704ab07 Update all of the libclang code corresponding to the preprocessor
MacroInstantiation -> MacroExpansion rename. Internally, everything is
switched.

Introduce a new cursor kind enum with the new name, but retain the old
name as an alias so that we don't break backwards compatibility.

Also update the debug printing routine to use 'macro expansions' as its
explicitly not guaranteed to be stable, and mechanically switch the test
cases over to that.

2011-07-14 08:41:15 +00:00
Chandler Carruth a88a221855 Move the rest of the preprocessor terminology from 'instantiate' and
variants to 'expand'. This changed a couple of public APIs, including
one public type "MacroInstantiation" which is now "MacroExpansion". The
rest of the codebase was updated to reflect this, especially the
libclang code. Two of the C++ (and thus easily changed) libclang APIs
were updated as well because they pertained directly to the old
MacroInstantiation class.

No functionality changed.
