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.

Use, to complement the version that takes a use_iterator.

John McCall 6538c93050 Qualified lookup through using declarations. Diagnose a new type of ambiguity.
Split the various ambiguous result enumerators into their own enum.  Tests
for most of C++ [namespace.qual].

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();
  ^~~
t.cpp:3:3: note: 'f' declared here
B 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.

Kevin Enderby a2b99107c4 Added another bit of the ARM target assembler to llvm-mc to parse register
lists.  Changed ARMAsmParser::MatchRegisterName to return -1 instead of 0 on
errors so 0-15 values could be returned as register numbers.  Also added the
rest of the arm register names to the currently hacked up version to allow more
testing.  Some changes to ARMAsmParser::ParseOperand to give different errors
for things not yet supported and some additions to the hacked
ARMAsmParser::MatchInstruction to allow more testing for now.

Douglas Gregor 7f34baeb4b When declaring a friend class template, we may end up finding an
injected-class-name (e.g., when we're referring to other
specializations of the current class template). Make sure that we see
the template rather than the injected-class-name. Fixes PR4768.

Dan Gohman e19c1810d7 isTriviallyReMaterializable checks the
TargetInstrDesc::isRematerializable flag, so it isn't necessary to do
this check in its callers.

Dan Gohman 7d9dffb413 Fix the x86 test-shrink optimization so that it doesn't shrink comparisons
when one of the bits being tested would end up being the sign bit in the
narrower type, and a signed comparison is being performed, since this would
change the result of the signed comparison. This fixes PR5132.

Fariborz Jahanian 0fe5e0308e Produce good looking diagnostics on ambiguous built-in operators.
Now we produce things like:
bug1.cpp:21:11: error: use of overloaded operator '->*' is ambiguous
        int i = c->*pmf;        // expected-error {{use of overloaded operator '->*' is ambiguous}} \
                ~^  ~~~
bug1.cpp:21:11: note: built-in candidate operator ->* ('struct A volatile *', 'int const struct A::*')
bug1.cpp:21:11: note: built-in candidate operator ->* ('struct A volatile *', 'int restrict struct A::*')
...
