NAKAMURA Takumi 226e10edff [CMake] Let add_public_tablegen_target() provide intrinsics_gen, too. 
I think, in principle, intrinsics_gen may be added explicitly.
That said, it can be added incidentally, since each target already has dependencies to llvm-tblgen.
Almost all source files depend on both CommonTaleGen and intrinsics_gen.

Explicit add_dependencies() have been pruned under lib/Target.

Juergen Ributzka d12ccbd343 [weak vtables] Remove a bunch of weak vtables 
This patch removes most of the trivial cases of weak vtables by pinning them to
a single object file. The memory leaks in this version have been fixed. Thanks
Alexey for pointing them out.

Alexey Samsonov 49109a279c Revert r194865 and r194874. 
This change is incorrect. If you delete virtual destructor of both a base class
and a subclass, then the following code:
  Base *foo = new Child();
  delete foo;
will not cause the destructor for members of Child class. As a result, I observe
plently of memory leaks. Notable examples I investigated are:
ObjectBuffer and ObjectBufferStream, AttributeImpl and StringSAttributeImpl.

Tim Northover 31d093c705 ISelDAG: spot chain cycles involving MachineNodes 
Previously, the DAGISel function WalkChainUsers was spotting that it
had entered already-selected territory by whether a node was a
MachineNode (amongst other things). Since it's fairly common practice
to insert MachineNodes during ISelLowering, this was not the correct
check.

Looking around, it seems that other nodes get their NodeId set to -1
upon selection, so this makes sure the same thing happens to all
MachineNodes and uses that characteristic to determine whether we
should stop looking for a loop during selection.

This should fix PR15840.

Venkatraman Govindaraju 55ecb10e99 [Sparc] Correctly handle call to functions with ReturnsTwice attribute. 
In sparc, setjmp stores only the registers %fp, %sp, %i7 and %o7. longjmp restores
the stack, and the callee-saved registers (all local/in registers: %i0-%i7, %l0-%l7)
using the stored %fp and register windows. However, this does not guarantee that the longjmp
will restore the registers, as they were when the setjmp was called. This is because these
registers may be clobbered after returning from setjmp, but before calling longjmp.

This patch prevents the registers %i0-%i5, %l0-l7 to live across the setjmp call using the register mask.

Also clean up the arguments to all the MOVCC instructions so the
operands always are (true-val, false-val, cond-code).

Venkatraman Govindaraju 3320e5a921 [Sparc] Rearrange integer registers' allocation order so that register allocator will use I and G registers before using L and O registers. 
Also, enable registers %g2-%g4 to be used in application and %g5 in 64 bit mode.

Venkatraman Govindaraju 641b0b5a21 [Sparc] Implements hasReservedCallFrame and hasFP. 
This is to generate correct framesetup code when the function
 has variable sized allocas.

Rafael Espindola 227144c23c Remove the MachineMove class. 
It was just a less powerful and more confusing version of
MCCFIInstruction. A side effect is that, since MCCFIInstruction uses
dwarf register numbers, calls to getDwarfRegNum are pushed out, which
should allow further simplifications.

I left the MachineModuleInfo::addFrameMove interface unchanged since
this patch was already fairly big.

Jakob Stoklund Olesen 84ebe25db7 Passing arguments to varags functions under the SPARC v9 ABI. 
Arguments after the fixed arguments never use the floating point
registers.

Jakob Stoklund Olesen a41f91ea8e Compile varargs functions for SPARCv9. 
With a little help from the frontend, it looks like the standard va_*
intrinsics can do the job.

Also clean up an old bitcast hack in LowerVAARG that dealt with
unaligned double loads. Load SDNodes can specify an alignment now.

Still missing: Calling varargs functions with float arguments.
