Sebastian Redl 5d43164bc2 Implement the core checking for compatible exception specifications in assignment and initialization.
The exception specification of the assignee must be the same or a subset of the target. In addition, exception specifications on arguments and return types must be equivalent, but this is not implemented yet.
This currently produces two diagnostics for every invalid assignment/initialization, due to the diagnostic produced outside PerformImplicitConversion, e.g. in CheckSingleInitializer. I don't know how to suppress this; in any case I think it is the wrong place for a diagnostic, since there are other diagnostics produced inside the function. So I'm leaving it as it is for the moment.

Chris Lattner 65e69a77e1 use a typedef instead of spelling out an insane type. Yay for auto someday.

Chris Lattner 84095071ea Change jump threading to use the new SSAUpdater class instead of
DemoteRegToStack.  This makes it more efficient (because it isn't
creating a ton of load/stores that are eventually removed by a later
mem2reg), and more slightly more effective (because those load/stores
don't get in the way of threading).

Chris Lattner 60d4e69c81 Implement an efficient and fully general SSA update mechanism that
works on unstructured CFGs.  This implements PR217, our oldest open PR.

Chris Lattner 71db463fcf add some WeakVH::operator='s. Without these, assigning
a Value* to a WeakVH was constructing a temporary WeakVH
(due to the implicit assignment operator).  This avoids
that cost.

Dan Gohman b8120770b4 Create a new InstrEmitter class for translating SelectionDAG nodes
into MachineInstrs. This is mostly just moving the code from
ScheduleDAGSDNodesEmit.cpp into a new class. This decouples MachineInstr
emitting from scheduling.

Dan Gohman a22f2d8614 Make getMachineNode return a MachineSDNode* instead of a generic SDNode*
since it won't do any folding. This will help avoid some inconvenient
casting.

Dan Gohman e919de5acf Replace X86's CanRematLoadWithDispOperand by calling the target-independent
MachineInstr::isInvariantLoad instead, which has the benefit of being
more complete.

Anders Carlsson 7f84ed9287 Add CheckCallReturnType and start using it for regular call expressions. This will improve error messages. For
struct B;

B f();

void g() {

We now get

  f();

Dan Gohman 918ec53c64 The ScheduleDAG framework now requires an AliasAnalysis argument, though
it isn't needed in the ScheduleDAGSDNodes schedulers.

Dan Gohman 50998f4584 Update this test; the code is the same but it gets counted as one
fewer remat.

Dan Gohman 4a72f7ab53 Mark the LDR instruction with isReMaterializable, as it is rematerializable
when loading from an invariant memory location.

llvm-svn: 83688
2009-10-09 23:28:27 +00:00
Dan Gohman 87b02d5bbc Factor out LiveIntervalAnalysis' code to determine whether an instruction
is trivially rematerializable and integrate it into
TargetInstrInfo::isTriviallyReMaterializable. This way, all places that
need to know whether an instruction is rematerializable will get the
same answer.

This enables the useful parts of the aggressive-remat option by
default -- using AliasAnalysis to determine whether a memory location
is invariant, and removes the questionable parts -- rematting operations
with virtual register inputs that may not be live everywhere.

Douglas Gregor 8413751fab Experimental, ultra-hacking Emacs minor mode for Clang-based code completion.
llvm-svn: 83681
2009-10-09 22:17:40 +00:00
Douglas Gregor 58acf32af2 Minor tweaks for code-completion:
- Filter out unnamed declarations
  - Filter out declarations whose names are reserved for the
  implementation (e.g., __bar, _Foo) 
  - Place OVERLOAD: or COMPLETION: at the beginning of each
  code-completion result, so we can easily separate them from other
  compilation results.

Jeffrey Yasskin 307c053f2e ExecutionEngine::clearGlobalMappingsFromModule failed to remove reverse
mappings, which could cause errors and assert-failures.  This patch fixes that,
adds a test, and refactors the global-mapping-removal code into a single place.
