Tanya Lattner f9d41df093 Merge constant array and structures. This will create a global variables for arrays and structs that are constant and their initializer is constant. It is on by default but can be disable with the flag -fno-merge-all-constants.

Mike Stump 71609a2874 Split out return adjustments in thunks from this adjustment in thunks 
so the optimizer can tailcall into the return value adjustment thunk.
This improves codesize for complex hierarchies.

 2009-11-03 23:50:34 +00:00
Mike Stump 53f9ded62b Refine volatile handling, specifically, we must have the canonical 
type to look at the volatile specifier.  I found these all from just
hand auditing the code.

Anders Carlsson 32e1b1c169 Get throws limping along, still a bunch of FIXMEs. Too bad we don't support catching anything yet :)

Nuno Lopes 09bd8656c3 make clang emit undefs for padding of structs and unions instead of zeros. this enables constant compaction optimizations.

Chris Lattner 6c4d255bf3 Implement clang support for indirect branch and address of label 
using the new LLVM support for this.  This is temporarily hiding
behind horrible and ugly #ifdefs until the time when the optimizer
is stable (hopefully a week or so).  Until then, lets make it "opt in" :)

Douglas Gregor 05925031f7 Mangle based on the declaration we're given, not the canonical 
declaration, since attributes that affect mangling may have been added
to subsequent declarations. However, to determine the linkage of the
declaration, we need to look at the canonical declaration. Fixes PR4412.

 2009-10-27 23:36:26 +00:00
Douglas Gregor b7e5c847c4 Implement proper linkage for explicit instantiation declarations of 
inlined functions. For example, given

  template<typename T>
  class string {
    unsigned Len;

  public:
    unsigned size() const { return Len; }
  };

  extern template class string<char>;

we now give the instantiation of string<char>::size
available_externally linkage (if it is ever instantiated!), as
permitted by the C++0x standard.

Mike Stump 876387ba4f __builtin_object_size refinements. Ensure we handle expressions with 
side-effects up front, as when we switch to the llvm intrinsic call
for __builtin_object_size later, it will have two evaluations.

We also finish off the intrinsic version of the code so we can just
turn it on once llvm has the intrinsic.

Mike Stump 7a484dd6a9 Prep for future __builtin_object_size refinements. The theory is that 
someone will add an llvm intrinsic for us to use, so the optimizer can
figure out the hard cases.  WIP.

For those that want to help, double check with Eric before starting.
He has a bit of code this will plug into.
