Chris Lattner 79b8c79242 verify that alignments are always a power of 2

 2005-11-05 21:57:54 +00:00
Nate Begeman 848622f87f Add support alignment of allocation instructions. 
Add support for specifying alignment and size of setjmp jmpbufs.

No targets currently do anything with this information, nor is it presrved
in the bytecode representation.  That's coming up next.

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

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

Chris Lattner 2c7d177d25 Allow these methods to take a generic Value* to simplify clients. Use 
const_cast instead of c casts.

Chris Lattner f711f8db41 Make sure that we always grow a multiple of 2 operands.

Chris Lattner afdb3de4d7 Merge InstrTypes.cpp into this file 
Adjust to changes in the User class, operand handling is very different.
PHI node and switch statements must handle explicit resizing of operand
lists.

Alkis Evlogimenos 531e901deb Make ReturnInst accept a value of type void as the return value. The 
ReturnInst constructed is the same as if NULL was passed instead of
the void value.

Chris Lattner f22be93428 Move the implementation of the instructions clone methods to this file so 
that the vtables for these classes are only instantiated in this translation
unit, not in every xlation unit they are used.
