Eli Friedman 1efaaeaa69 Initial implementation of arbitrary fixed-width integer types.
Currently only used for 128-bit integers.

Note that we can't use the fixed-width integer types for other integer 
modes without other changes because glibc headers redefines (u)int*_t 
and friends using the mode attribute.  For example, this means that uint64_t
has to be compatible with unsigned __attribute((mode(DI))), and 
uint64_t is currently defined to long long.  And I have a feeling we'll 
run into issues if we try to define uint64_t as something which isn't 
either long or long long.

This doesn't get the alignment right in most cases, including 
the 128-bit integer case; I'll file a PR shortly.  The gist of the issue 
is that the targets don't really expose the information necessary to 
figure out the alignment outside of the target description, so there's a 
non-trivial amount of work involved in getting it working right.  That 
said, the alignment used is conservative, so the only issue with the 
current implementation is ABI compatibility.

This makes it trivial to add some sort of "bitwidth" attribute to make 
arbitrary-width integers; I'll do that in a followup.

We could also use this for stuff like the following for compatibility 
with gcc, but I have a feeling it would be a better idea for clang to be 
consistent between C and C++ modes rather than follow gcc's example for 
C mode.
struct {unsigned long long x : 33;} x;
unsigned long long a(void) {return x.x+1;}

Douglas Gregor adb0201418 Add mangling for variadic functions and conversion functions
llvm-svn: 64425
2009-02-13 01:28:03 +00:00
Douglas Gregor 5fec5b0495 Add basic support for C++ name mangling according to the Itanium C++
ABI to the CodeGen library. Since C++ code-generation is so
incomplete, we can't exercise much of this mangling code. However, a
few smoke tests show that it's doing the same thing as GCC. When C++
codegen matures, we'll extend the ABI tester to verify name-mangling
as well, and complete the implementation here.

At this point, the major client of name mangling is in the uses of the
new "overloadable" attribute in C, which allows overloading. Any
"overloadable" function in C (or in an extern "C" block in C++) will
be mangled the same way that the corresponding C++ function would be
mangled.

Mike Stump ab3afd8f2d Initial codegen for block literals. This is a work in progress. I've

Steve Naroff b76051534c Several cleanups:
- rename isObjCIdType/isObjCClassType -> isObjCIdStructType/isObjCClassStructType. The previous name didn't do what you would expect.
- add back isObjCIdType/isObjCClassType to do what you would expect. Not currently used, however many of the isObjCIdStructType/isObjCClassStructType clients could be converted over time.
- move static Sema function areComparableObjCInterfaces to ASTContext (renamed to areComparableObjCPointerTypes, since it now operates on pointer types).

Douglas Gregor 8bf4205c70 Start processing template-ids as types when the template-name refers
to a class template. For example, the template-id 'vector<int>' now
has a nice, sugary type in the type system. What we can do now:

  - Parse template-ids like 'vector<int>' (where 'vector' names a
    class template) and form proper types for them in the type system.
  - Parse icky template-ids like 'A<5>' and 'A<(5 > 0)>' properly,
    using (sadly) a bool in the parser to tell it whether '>' should
    be treated as an operator or not.

This is a baby-step, with major problems and limitations:
  - There are currently two ways that we handle template arguments
  (whether they are types or expressions). These will be merged, and,
  most likely, TemplateArg will disappear.
  - We don't have any notion of the declaration of class template
  specializations or of template instantiations, so all template-ids
  are fancy names for 'int' :)

Daniel Dunbar 1e8052b36d Add -femit-all-decls codegen option.
- Emits all declarations, even unused (static) ones.
 - Useful when doing minimization of codegen problems (otherwise

Daniel Dunbar 4d22e4975a Change construction of common ObjC functions to use CGCall
infrastructure to construct function type.
 - For consistencty, we should probably always use this to construct
   function types, but these are absolutely necessary to ensure that
   we can emit calls to these functions.

Daniel Dunbar fc7c76159c x86_64 ABI: Initial implementation of ABI compliant parameter passing.
- Now only 27/500 failures on ABITest single argument tests; from

 - As with return types, a large percentage of these are likely to be
   gcc bugs, not yet reviewed.

Also, fix bug in handling of Ignore ABI type in argument lists.
