Douglas Gregor 968d633176 Collect the code that imports all of the members of a declaration context into a single function, ImportDeclContext. Use it rather than explicit loops. No functionality change.

Chandler Carruth 8f2548112e Commiting a revert from dgregor of a bit of destructor logic until we can
figure out how not to break lots of code using this. See PR6358 and PR6359 for
motivating examples. FIXME's left in the code and the test.

Chris Lattner 4e5d6788b3 when a match fails and we have to rollback, make sure to keep 'N' in
sync with the top of stack.  This fixes a bunch of failures on larger
testcases.

Chandler Carruth f50ef6ed9a Make Decl::isOutOfLine() virtual, and use that to determine when definitions
are for out of line declarations more easily. This simplifies the logic and
handles the case of out-of-line class definitions correctly. Fixes PR6107.

Chris Lattner eb3c0435b7 fix a table size miscomputation, target opcodes are 2 bytes.
With this, the matcher actually works reasonably well, but
crashes on larger examples in the scheduler.

Ted Kremenek 2fb89539f7 Clang really intends to reject attribute 'warn_unused_result' on Objective-C methods, but
instead it crashes on them.  We might extend this attribute to work on methods, but for
now fix the crasher.  Addresses <rdar://problem/7670939>.

Johnny Chen a07c9c7c56 Undo r96654. The printing of ARM shift instructions in canonical forms can be
handled in ARMInstPrinter.cpp.

Charles Davis 6184c63f16 Reduce size of 'StackAlignment' field from 5 to 3 bits. Seriously, who needs a
2GB-aligned stack anyway? 256 bytes is plenty. Requested by Chris.

Chris Lattner 132df652a4 Lots of improvements to the new dagisel emitter. This gets it to
the point where it is to the 95% feature complete mark, it just
needs result updating to be done (then testing, optimization 
etc).

More specificallly, this adds support for chain and flag handling
on the result nodes, support for sdnodexforms, support for variadic
nodes, memrefs, pinned physreg inputs, and probably lots of other
stuff.

In the old DAGISelEmitter, this deletes the dead code related to
OperatorMap, cleans up a variety of dead stuff handling "implicit
remapping" from things like globaladdr -> targetglobaladdr (which
is no longer used because globaladdr always needs to be legalized),
and some minor formatting fixes.

Chris Lattner 18a32ce0f3 rename SelectScalarSSELoad -> SelectScalarSSELoadXXX and rewrite
it to follow the mode needed by the new isel.  Instead of returning
the input and output chains, it just returns the (currently only one,
which is a silly limitation) node that has input and output chains.

Since we want the old thing to still work, add a new 
SelectScalarSSELoad to emulate the old interface.  The XXX suffix
and the wrapper will eventually go away.

Douglas Gregor 0286b46702 Only parse C++0x attribute specifiers in declarators when in C++0x
mode. This allows us to detect invalid VLAs in Objective-C++
mode. This should be the last of <rdar://problem/7660386>.

Douglas Gregor 337caf9e3e Implement C++ name lookup for instance variables of Objective-C classes
from an instance method. Previously, we were following the Objective-C
name lookup rules for ivars, which are of course completely different
from and incompatible with the Objective-C++ rules.

For the record, the Objective-C++ rules are the sane ones.

This is another part of <rdar://problem/7660386>.

Duncan Sands d0bf6f640f Revert commits 96556 and 96640, because commit 96556 breaks the
dragonegg self-host build.  I reverted 96640 in order to revert
96556 (96640 goes on top of 96556), but it also looks like with
both of them applied the breakage happens even earlier.  The
symptom of the 96556 miscompile is the following crash:

  llvm[3]: Compiling AlphaISelLowering.cpp for Release build
  cc1plus: /home/duncan/tmp/tmp/llvm/lib/CodeGen/SelectionDAG/SelectionDAG.cpp:4982: void llvm::SelectionDAG::ReplaceAllUsesWith(llvm::SDNode*, llvm::SDNode*, llvm::SelectionDAG::DAGUpdateListener*): Assertion `(!From->hasAnyUseOfValue(i) || From->getValueType(i) == To->getValueType(i)) && "Cannot use this version of ReplaceAllUsesWith!"' failed.
  Stack dump:
  0.	Running pass 'X86 DAG->DAG Instruction Selection' on function '@_ZN4llvm19AlphaTargetLowering14LowerOperationENS_7SDValueERNS_12SelectionDAGE'
  g++: Internal error: Aborted (program cc1plus)

This occurs when building LLVM using LLVM built by LLVM (via
dragonegg).  Probably LLVM has miscompiled itself, though it
may have miscompiled GCC and/or dragonegg itself: at this point
of the self-host build, all of GCC, LLVM and dragonegg were built
using LLVM.  Unfortunately this kind of thing is extremely hard
to debug, and while I did rummage around a bit I didn't find any
smoking guns, aka obviously miscompiled code.

Found by bisection.

Some dag combiner goodness:
Transform br (xor (x, y)) -> br (x != y)
Transform br (xor (xor (x,y), 1)) -> br (x == y)
Also normalize (and (X, 1) == / != 1 -> (and (X, 1)) != / == 0 to match to "test on x86" and "tst on arm"

John McCall b81884d347 More refactoring around constructor/destructor code generation.
Fix some bugs with function-try-blocks and simplify normal try-block
code generation.

This implementation excludes a deleting destructor's call to
operator delete() from the function-try-block, which I believe
is correct but which I can't find straightforward support for at
a moment's glance.
