Dan Gohman 53efeb0e45 Fix a bug in the trip-count computation with And/Or. If either of the 
sides is CouldNotCompute, the resulting exact count must be CouldNotCompute.

Bob Wilson 2e076c4e02 Add support for ARM's Advanced SIMD (NEON) instruction set. 
This is still a work in progress but most of the NEON instruction set
is supported.

Ted Kremenek e5e8b0b09b Refactor some of the logic in MemRegionManager for constructing regions using 
member template functions and traits. The idea is to allow MemRegionManager to
construct subclasses of MemRegion that aren't declared in MemRegion.h (e.g.,
checker-specific regions).

Douglas Gregor 77b50e1126 Implement implicit instantiation of the member functions of a class template 
specialization. At present, all implicit instantiations occur at the
end of the translation unit.

 2009-06-22 22:08:45 +00:00
Bob Wilson e67b77028e Add explicit types for shift count constants. This is in preparation for 
another change that makes the types ambiguous (at least as far as tablegen
is concerned).

Dan Gohman 2636693a3c Fix llvm::ComputeNumSignBits to handle pointer types 
conservatively correctly, instead of aborting.

Dale Johannesen 315fb72d36 Fix memcpy expansion so it won't generate invalid 
types for the target (I think).  This was breaking
the PPC32 calling sequence.

Douglas Gregor 0b6a6242ed Rework the way we track which declarations are "used" during 
compilation, and (hopefully) introduce RAII objects for changing the
"potentially evaluated" state at all of the necessary places within
Sema and Parser. Other changes:

  - Set the unevaluated/potentially-evaluated context appropriately
    during template instantiation.
  - We now recognize three different states while parsing or
    instantiating expressions: unevaluated, potentially evaluated, and
    potentially potentially evaluated (for C++'s typeid).
  - When we're in a potentially potentially-evaluated context, queue
    up MarkDeclarationReferenced calls in a stack. For C++ typeid
    expressions that are potentially evaluated, we will play back
    these MarkDeclarationReferenced calls when we exit the
    corresponding potentially potentially-evaluated context.
  - Non-type template arguments are now parsed as constant
    expressions, so they are not potentially-evaluated.

Evan Cheng 8cbbc7944d Fix another register coalescer crash: forgot to check if the instruction being updated has already been coalesced.

Owen Anderson 86837616f7 Banish global state from ScalarEvolution! SCEV uniquing is now done by tables attached to the ScalarEvolution pass. 
This also throws out the SCEV reference counting scheme, as the the SCEVs now have a lifetime controlled by the
ScalarEvolution pass.

Note that SCEVHandle is now a no-op, and will be remove in a future commit.

llvm-svn: 73889
 2009-06-22 18:01:28 +00:00
Fariborz Jahanian 3a36343b88 Remove ImplicitMustBeDefined, use universal 'Used' flag 
instead. Do the implicit default ctor checking in MarkDeclarationReferenced.

 2009-06-22 17:30:33 +00:00
Bob Wilson 360eef0782 Fix llvm-gcc build for armv6t2 and later architectures. The hasV6T2Ops 
predicate does not check if Thumb mode is enabled, and when in ARM mode
there are still some checks for constant-pool use that need to run.

Argyrios Kyrtzidis 49abd4d95b Addressing Doug's suggestions:

Dan Gohman ed627385de Make use of getUMinFromMismatchedTypes when computing backedge-taken 
counts for loops with multiple exits, replacing more conservative code
which only handled constants. This is derived from a patch by
Nick Lewycky.

This also fixes llc aborts in ClamAV and others, as
getUMinFromMismatchedTypes takes care of balancing the types before
working with them.

llvm-svn: 73884
 2009-06-22 15:09:28 +00:00
Dan Gohman 2bc22305d2 Add a getUMinFromMismatchedTypes helper function.

Chris Lattner 1d1fe918de process memory operands with a parenthesized expression for a displacement, 
like "(4+5)(%eax)".

 2009-06-22 06:35:58 +00:00
Chris Lattner 7fdbce7a60 Implement full support for parsing primary expressions. We can now parse 
all of health and voronoi (ignoring directives).  We only get 409 lines into
176.gcc though because we don't have binary operators yet:

Parsing 176.gcc.llc.s:409: unexpected token in operand list
	movsbl	_arityvec+1(,%edi,8), %eax
	      	         ^
