they are re-checked on instantiation.

Dan Gohman fefbff9cd8 When testing whether a given SCEV depends on a temporary symbolic 
name, test whether the SCEV itself is that temporary symbolic name,
in addition to checking whether the symbolic name appears as a
possibly-indirect operand.

Chris Lattner b02cdaaa9c Check in the first big step of rewriting DAGISelEmitter to 
produce a table based matcher instead of gobs of C++ Code.

Though it's not done yet, the shrinkage seems promising,
the table for the X86 ISel is 75K and still has a lot of 
optimization to come (compare to the ~1.5M of .o generated
the old way, much of which will go away).

The code is currently disabled by default (the #if 0 in
DAGISelEmitter.cpp).  When enabled it generates a dead
SelectCode2 function in the DAGISel Header which will
eventually replace SelectCode.

There is still a lot of stuff left to do, which are
documented with a trail of FIXMEs.

Chris Lattner 8fd1fe1612 give SDValue an operator->, allowing V->isTargetOpcode() and 
many other natural things.

Chris Lattner f0520da7a1 don't make insanely large node numbers for no reason, 
packing somewhat densely is better than not.

Mikhail Glushenkov 5352f07f2c Revert r96130 ("Forward parameter options as '-option=param'"). 
This behaviour must be configurable.

Chris Lattner 115158fa4f enhance raw_svector_ostream::write_impl to work with unbuffered streams, 
which may call write_impl on things that are not the usual buffer.

llvm-svn: 96209

Chris Lattner f733d75892 make PadToColumn return the stream so you can use: 
OS.PadToColumn(42) << "foo";

John McCall 7538eec67b When emitting an aggregate into a temporary, make sure we set the alignment 
on the alloca.

The fact that codegen makes this class of bug so wonderfully easy to make is
embarrassing.

llvm-svn: 96204

Dan Gohman 4d8feb11dd When restoring a saved insert location, check to see if the saved 
insert location has become an "inserted" instruction since the time
it was saved. If so, advance to the first non-"inserted" instruction.

Ted Kremenek 4ba99bee2a clang::Attr objects should be treated as AST nodes as well by 
the LLVMConventionsChecker.

Chris Lattner 53c39ba3c1 clean up a bunch of code, move some random predicates 
on TreePatternNode to be methods on TreePatternNode.

Chris Lattner 4aa57ba3ef mark "addr" as having type "iPTR", eliminating some type comparisons 
in hte generated dag isel fil.

llvm-svn: 96193
 2010-02-14 21:53:19 +00:00
Chris Lattner b3d9942c51 remove the DisablePatternForFastISel predicate, which is a check 
that predated -fast-isel which attempted to speed up the dag pattern
matchers at -O0.  Since fast-isel is around, this is basically 
obsolete and removing it shrinks the generated dag isels.

Ted Kremenek 4853131459 Add LLVM conventions check that scans for AST elements (types, stmts, decls) 
that allocate heap memory.

llvm-svn: 96184

Ted Kremenek 988805c81e Change LLVMConventionsChecker to accept an entire translation unit instead 
of operating on each code decl.  This exposes two flaws in AnalysisConsumer
that should eventually be fixed:

(1) It is not possible to associate multiple "actions" with a single
    command line argument.  This will require the notion of an
	"analysis" group, and possibly tablegen support.  (although eventually
    we want to support dynamically loading analyses as well)

(2) AnalysisConsumer may not actually be scanning the declarations in namespaces.
    We'll experiment first in LLVMConventionsChecker before changing the
    behavior in AnalysisConsumer.

 2010-02-14 18:51:20 +00:00
Dan Gohman bb7d52213c When complicated expressions are broken down into subexpressions 
with multiplication by constants distributed through, occasionally
those subexpressions can include both x and -x. For now, if this
condition is discovered within LSR, just prune such cases away,
as they won't be profitable. This fixes a "zero allocated in a
base register" assertion failure.
