Work in progress.

New C++ PBQP solver. Currently about as fast (read _slow_) as the old C based solver, but I'll be working to improve that. The PBQP allocator has been updated to use the new solver.

llvm-svn: 78354

produced a CFG it wasn't prepared for.

llvm-svn: 78351

llvm-svn: 78350

with array accesses. In the process, refactor some common logic in
RetrieveElement() and RetrieveField() into RetrieveFieldOrElementCommon().

llvm-svn: 78349

TransformStmt, into the tree transformer.

rtti so we can properly test it.  Refactor code a little.  Still a
work in progress.

llvm-svn: 78343

involving reasoning about unions (which we don't handle yet).

llvm-svn: 78342

module as first argument.

llvm-svn: 78340

guard its report on GNUMode.

llvm-svn: 78338

If we need it one day, there is nothing wrong with putting it back in.

Permit a class to friend its class members in C++ 98, as long as extensions
are enabled (and even when they aren't, only give an extwarn about it).

don't recurs and crash.

llvm-svn: 78322

Add parameter to pattern classes to enable an itinerary to be specified for instructions. For now just use the existing itineraries or NoItinerary.

llvm-svn: 78321

llvm-svn: 78320

creation activity into the target-specific subclasses of TLOF.
Before this, globals with explicit sections could be created by
the base class.

1. make getOrCreateSection protected, add a new getExplicitSectionGlobal
   pure virtual method to assign sections to globals with a specified
   section.
2. eliminate getSpecialCasedSectionGlobals, which is now PIC specific.
3. eliminate the getKindForNamedSection virtual method, which is
   now just a static method for ELF.
4. Add implementions of getExplicitSectionGlobal for ELF/PECOFF/Darwin/PIC16.
   They are now all detangled and understandable, woo! :)

llvm-svn: 78319

- start support for new PEI w/reg alloc, allow running RS from emit{Pro,Epi}logue() target hooks.
- fix minor issue with recursion detection.

llvm-svn: 78318

creating them directly in the pic16 asmprinter.

llvm-svn: 78317

we were going to enter into the scope of a class template or class
template partial specialization, rebuild that type so that it can
refer to members of the current instantiation, as in code like

  template<typename T>
  struct X {
    typedef T* pointer;
    pointer data();
  };

  template<typename T>
  typename X<T>::pointer X<T>::data() { ... }

Without rebuilding the return type of this out-of-line definition, the
canonical return type of the out-of-line definition (a TypenameType)
will not match the canonical return type of the declaration (the
canonical type of T*).

and LowerReturn, to verify that the targets' hooks have respected some
of their postconditions.

llvm-svn: 78312

types don't have any return values, from CodeGen's perspective.
This fixes PR4688.

llvm-svn: 78311

llvm-svn: 78310

optimize and check for non-optimal code, but until the frontend is as
powerful as fold...
