2403cc41ea Unfortunately we now require C++ code to isel Bcc, conditional moves, etc.

ef8a1bcbc3 Each ARM use predicate operand is now made up of two components. The new component is the CPSR register.

8b0cbaff08 - Added zero_reg def to stand for register 0. 
- Added two variants of PredicateOperand: ImmutablePredicateOperand, whose predicate does not change after isel; PredicateDefOperand, which represent a predicate defintion operand.

Still need to have JIT generate this code.

6599e49230 Add functionality to value number GEP instructions. This also provides the infrastructure that will 
be used for function calls.  NOTE: This does not yet do any transformation of GEPs or function calls.

c40306b84b Remove BFtoLLVM. It was old, and a poor example because it didn't use best practices for making 
a LLVM frontend in C++.  Maybe someday it will be rewritten..

cbbc232425 We really should not have this version number in SO many makefiles. This should also probably change to svn instead of cvs, but leaving it for now.

eb46e6e629 Vector results may be returned in XMM0 and XMM1, not just XMM0. With 
the recent lowering changes, this allows types like <4 x double> to
be returned, using two vector registers.

68f0cbccfb Replace ExpandScalarFormalArgs and ExpandScalarCallArgs with the newly 
refactored getCopyFromParts and getCopyToParts, which are more general.
This effectively adds support for lowering illegal by-val vector call
arguments.

5fe8266d04 Teach GetNegatedExpression to negate 0-B to B in UnsafeFPMath mode, and 
visitFSUB to fold 0-B to -B in UnsafeFPMath mode. Also change visitFNEG
to use isNegatibleForFree/GetNegatedExpression instead of doing a subset
of the same thing manually.

This fixes test/CodeGen/X86/negative-sin.ll.
