code that creates the label too.

in the included testcase.

counted objects that maintain their own internal reference count.
This smart pointer implementation is compatible with LLVM-style
down-casting (see in llvm: include/llvm/Support/Casting.h).

Implemented "RefCounted", a base class that objects that wish to be
managed using IntrusiveSPtrs can subclass.

Reference counted objects are being targeted for use in path-sensitive
dataflow analyses where managing many live objects becomes difficult.

asm to die with:

ScheduleDAG.cpp:269: failed assertion `false && "Couldn't find the register class"'

instead of:
failed assertion `RegMap->getRegClass(VReg) == RC && "Register class of operand and regclass of use don't agree!"'

yay.

so that we don't emit an error on the #endif.  Suggestion by Neil.

into a separate header file.

Next step: merging PostDominatorCalculation.h with DominatorCalculation.h.

llvm-svn: 42251

and the PostDomTree version first.

llvm-svn: 42250

llvm-svn: 42249

change is not useful in and of itself, but it lays the groundwork for combining
the dominator and postdominator implementations.

Also, factor a few methods that are common to DominatorTree and PostDominatorTree
into DominatorTreeBase.  Again, this will make merging the two calculation methods
simpler in the future.

-sse to preserve intent of this test.

llvm-svn: 42247

keep f32 in SSE registers and f64 in x87.  This
is effectively a new codegen mode.
Change addLegalFPImmediate to permit float and
double variants to do different things.
Adjust callers.

'dir' exists in 'ocamldep -I dir ...', but recent ones demand that it actually
exists.

integer constant expressions.  The only questionable
thing is that we now reject:

void foo() {
  switch (1) {
  case (int)1.0e10000:
    ;
  }
}

with:

t.c:5:13: error: case label does not reduce to an integer constant
  case (int)1.0e10000:
       ~~~~~^~~~~~~~~

GCC accepts this, emitting the pedwarn:
t.c:5: warning: floating constant exceeds range of 'double'

APFloat straight through to LLVM now.
