Bob Wilson aff96b2132 Rename SuccessorNumber to GetSuccessorNumber.

 2010-02-16 21:06:42 +00:00
David Greene 9641d06809 Add support for emitting non-temporal stores for DAGs marked 
non-temporal.  Fix from r96241 for botched encoding of MOVNTDQ.

Add documentation for !nontemporal metadata.

Add a simpler movnt testcase.

Bob Wilson 6bfacb7393 Testcase for critical edge splitting with load PRE. 
llvm-svn: 96385
 2010-02-16 20:48:55 +00:00
Jim Grosbach 2284ddab56 Update Thumb2 to not use CarryDefIsUnused or CarryDefIsUsed predicates, but 
to have the predicate on the pattern itself instead. Support for the new
ISel. Remove definitions of CarryDefIsUnused and CarryDefIsUsed since they are
no longer used anywhere.

 2010-02-16 20:42:29 +00:00
Jim Grosbach 756ab53e60 Remove redundant setting of Defs. CPSR is already marked by the block level set of Defs.

Dan Gohman 6deab96c81 Refactor rewriting for PHI nodes into a separate function. 
llvm-svn: 96382
 2010-02-16 20:25:07 +00:00
Jim Grosbach 0a334d0df9 First step in eliminating the CarryDefIsUnused and CarryDefIsUsed predicates. 
They won't work with the new ISel mechanism, as Requires predicates are no
longer allowed to reference the node being selected. Moving the predicate to
the patterns instead solves the problem.

This patch handles ARM mode. Thumb2 will follow.

Johnny Chen 46c39d4f1f Added for disassembly the following instructions: 
o Store Return State (SRSW, SRS)
o Load/Store Coprocessor (LDC/STC and friends)
o MSR (immediate)

llvm-svn: 96376
 2010-02-16 19:45:20 +00:00
Daniel Dunbar 29a32dab4a Disable warn_unused_function for now, its breaking various project builds due to 
false positives.

llvm-svn: 96375
 2010-02-16 19:44:56 +00:00
Daniel Dunbar d004918ccb IRgen: Add CreateIRTemp, which creates a temporary alloca but with type converted "not-for-memory". Dunno a better name.

Douglas Gregor 71ad477ab3 Do not try to instantiate invalid declarations. It's a recipe for 
disaster. Fixes PR6161.

Chris Lattner 6c132331ee simplify this code. In the new world order there is no 
need to scan the entire subtree of the pattern anymore.

 2010-02-16 19:19:58 +00:00
Chris Lattner f8695c1ee9 convert the new matcher to check intermediate nodes for a single 
use and only call IsProfitableToFold/IsLegalToFold on the load
being folded, like the old dagiselemitter does.  This 
substantially simplifies the code and improves opportunities for
sharing.

llvm-svn: 96368
 2010-02-16 19:15:55 +00:00
Douglas Gregor fe17d2550b Improve parsing and instantiation of destructor names, so that we can 
now cope with the destruction of types named as dependent templates,
e.g.,

  y->template Y<T>::~Y()

Nominally, we implement C++0x [basic.lookup.qual]p6. However, we don't
follow the letter of the standard here because that would fail to
parse

  template<typename T, typename U>
  X0<T, U>::~X0() { }

properly. The problem is captured in core issue 339, which gives some
(but not enough!) guidance. I expect to revisit this code when the
resolution of 339 is clear, and/or we start capturing better source
information for DeclarationNames.

Fixes PR6152.

Chris Lattner 300048631b change dag isel emitter to only call 'IsProfitableToFold' on nodes 
with chains.  On interior nodes that lead up to them, we just directly
check that there is a single use.  This generates slightly more
efficient code.

Chris Lattner fff5ed4b55 when a diagnostic is an extension and has no other -W flag, 
indicate that it was enabled with -pedantic so people know
why they're getting them:

$ printf "int x;" | clang -xc - -pedantic
<stdin>:1:7: warning: no newline at end of file [-pedantic]
int x;
      ^

Charles Davis 163855f46d dllimport and dllexport are declspec attributes, too. They're also 
Win32-specific.

Also, fix a test to use FileCheck instead of grepping LLVM IR.

Fariborz Jahanian b6a68c0465 Minor rewriter cleanup and a test for a block rewriting bug. 
llvm-svn: 96361
 2010-02-16 17:26:03 +00:00
Bob Wilson 70aa8d0745 Fix pr6111: Avoid using the LR register for the target address of an indirect 
branch in ARM v4 code, since it gets clobbered by the return address before
it is used.  Instead of adding a new register class containing all the GPRs
except LR, just use the existing tGPR class.

Ted Kremenek 3eac2454dc Add test case showing that a recursive block that captures a block pointer that 
isn't marked '__block' is bad.

Anders Carlsson bc91b44a23 Add an extreme vbase offsets test. I'm kinda amazed that this works myself ;)

Fariborz Jahanian e1ff123214 Fix rewriter bug when function call inside block with block parameter 
causes C++ compile error (radar 7651312).

llvm-svn: 96352
 2010-02-16 16:21:26 +00:00
Anders Carlsson 14157939ab Fix a bug where we would not emit secondary vtables for bases of a primary base.

Duncan Sands cbd43f89ac Introduce isOpaqueTy and use it rather than isa<OpaqueType>. Also, move some 
methods to try to have the type predicates be more logically positioned.

llvm-svn: 96349
 2010-02-16 14:50:09 +00:00
Duncan Sands 19d0b47b1f There are two ways of checking for a given type, for example isa<PointerType>(T) 
and T->isPointerTy().  Convert most instances of the first form to the second form.
Requested by Chris.

 2010-02-16 07:26:36 +00:00
Chris Lattner 5ce8303950 generate code for node and pattern predicates. Note that this won't 
build if enabled, it will fail with constness issues. I'll resolve 
these next.

Anders Carlsson dc2dba306c More work on the new layout code. 
llvm-svn: 96328
 2010-02-16 04:49:44 +00:00
John McCall 6ce747220a When emitting complete destructors for classes with virtual bases, compute 
the offset to the virtual bases statically inside of relying on the virtual
base offsets in the object's vtable(s).  This is both more efficient and
sound against the destructor's manipulation of the vtables.

Also extract a few helper routines.

Oh and we seem to pass all tests with an optimized clang now.
