Andrew Trick a52f325c35 Converted LiveRegCycles to LiveRegGens. It's easier to work with and allows multiple nodes per cycle.

Andrew Trick 033efdf4d7 Fixes PR8823: add-with-overflow-128.ll
In the bottom-up selection DAG scheduling, handle two-address
instructions that read/write unspillable registers. Treat
the entire chain of two-address nodes as a single live range.

Ted Kremenek bd5fcdf803 It's amazing what you find when you actually
set the RUN line correctly in a test file!

Mark a bunch of tests for ArrayBoundCheckerV2
as FIXME's, as our current lack of pointer
arithmetic handling causes these to be all
false positives/negatives.

Jim Ingham a2cf2637da For the language check in GetObjectDescription, if we can't find a language runtime for the value we're looking at, BUT it IS at least a pointer, try the ObjCRuntime language. That's currently the only language runtime that has an object description method anyway...

Douglas Gregor ca4d91d9f6 Implement the part of C++0x [temp.arg.explicit]p3 that pertains to
parameter packs. In particular, a parameter pack not otherwise deduced
is deduced to an empty parameter pack.

The C++0x wording here is a bit unfortunate; this should really only
apply to function templates, and it mentions "trailing" parameter
packs, which doesn't really make sense in the context of function
templates. Will file a core issue separately.

Douglas Gregor d0ad2949fa Implement the rest of C++0x [temp.deduct.type]p9, which specifies that
the presence of a pack expansion anywhere except at the end of a

a non-deduced context.

Johnny Chen d5f66fcbac Add a test case for the SBFrame APIs. In particular, it uses the frame API to
get the argument values of the call stacks when stopped on the breakpoint.

Radar has been filed for the expected failures:
test failure: ./dotest.py -v -w -t -p TestFrames (argument values are wrong)

Benjamin Kramer 1f4dfbbcb0 DAGCombine add (sext i1), X into sub X, (zext i1) if sext from i1 is illegal. The latter usually compiles into smaller code.
example code:
unsigned foo(unsigned x, unsigned y) {
  if (x != 0) y--;
  return y;
}

before:
  _foo:                           ## @foo
    cmpl  $1, 4(%esp)             ## encoding: [0x83,0x7c,0x24,0x04,0x01]
    sbbl  %eax, %eax              ## encoding: [0x19,0xc0]
    notl  %eax                    ## encoding: [0xf7,0xd0]
    addl  8(%esp), %eax           ## encoding: [0x03,0x44,0x24,0x08]
    ret                           ## encoding: [0xc3]

after:
  _foo:                           ## @foo
    cmpl  $1, 4(%esp)             ## encoding: [0x83,0x7c,0x24,0x04,0x01]

    adcl  $-1, %eax               ## encoding: [0x83,0xd0,0xff]
    ret                           ## encoding: [0xc3]

Douglas Gregor 0f3feb4e8d Implement template argument deduction for pack expansions whose
pattern is a template argument, which involves repeatedly deducing
template arguments using the pattern of the pack expansion, then
bundling the resulting deductions into an argument pack.

We can now handle a variety of simple list-handling metaprograms using
variadic templates. See, e.g., the new "count" metaprogram.

Douglas Gregor d80ea20411 When performing template argument deduction where the argument is a
dependent template specialization type, the number of template
arguments need not match precisely. Rather than checking the number of
arguments eagerly (which does not consider argument packs), let the
deduction routine for template argument lists cope with too many/too
few arguments.
