Andrew Lenharth 107a0a7690 Testing a variable before it is defined doesn't work so well. It is a fairly small thing, so just let everyone build the .a file

Chris Lattner 6e709c1318 PHINode::hasConstantValue should never return the PHI itself, even if the 
PHI is its only operand.

Chris Lattner 1749aaa5e6 Fix an iterator invalidation problem when we decide a phi has a constant value

Chris Lattner 37774affb1 Invoke instructions do not dominate all successors 
llvm-svn: 22671
 2005-08-05 01:03:27 +00:00
Chris Lattner 6f58350daf Now that hasConstantValue is more careful w.r.t. returning values that only 
dominate the PHI node, this code can go away.  This also makes passes more
aggressive, e.g. implementing Transforms/CondProp/phisimplify2.ll

llvm-svn: 22670
 2005-08-05 01:02:04 +00:00
Chris Lattner bcd8d2c6e5 Use the bool argument to hasConstantValue to decide whether the client is 
prepared to deal with return values that do not dominate the PHI.  If we
cannot prove that the result dominates the PHI node, do not return it if
the client can't cope.

Nate Begeman b392321cae Fix a fixme in CondPropagate.cpp by moving a PhiNode optimization into 
BasicBlock's removePredecessor routine.  This requires shuffling around
the definition and implementation of hasContantValue from Utils.h,cpp into
Instructions.h,cpp

Reid Spencer 294715b33e Some cleanups for compilation with GCC 4.0.0 to remove warnings: 
* Use C++ style casts, not C style casts
* Abstract base classes should have virtual destructor.

Andrew Lenharth 5e177826fd Implement count leading zeros (ctlz), count trailing zeros (cttz), and count 
population (ctpop).  Generic lowering is implemented, however only promotion
is implemented for SelectionDAG at the moment.

More coming soon.

Reid Spencer 8edc8beacf Older compilers won't like the inline virtual destructor in the header file 
so we put the destructor in Pass.cpp and make it non-inline.

Chris Lattner 531f9e92d4 This mega patch converts us from using Function::a{iterator|begin|end} to

Chris Lattner 290d881f84 Delete the really inefficient method: void remove(const Type* Typ); 
Speed up the symbol stripping code by avoiding a linear search of the
type table.

Get rid of removeEntry(type_iterator), since 'remove' is exactly the same
operation.
