Brian Gaeke e383a14960 Use C++ math header instead of C version.

Brian Gaeke 20c888fa9f Rearrange #includes ... since there are fewer now I guess it's a win. 
(I also zapped printMachineCode() and printLabel() at the previous checkin,
but forgot to mention it.)

Brian Gaeke e1061018bf Convert PhyRegAlloc into a proper pass. 
PhyRegAlloc.cpp:
 Don't include TargetMachine.h or TargetRegInfo.h, because these are provided
  by PhyRegAlloc.h.
 Merge class RegisterAllocator into class PhyRegAlloc.
 Simplify & move ctor, dtor to PhyRegAlloc.h.
 Make some of PhyRegAlloc's reference members into pointer members,
  so they can be more easily messed with.
 MarkAllocatedRegs() becomes a member method, with fewer args.

PhyRegAlloc.h:
 Include Pass.h, TargetMachine.h and TargetRegInfo.h. Don't declare
  TargetRegInfo forward.
 Give AddedInstrns the obvious clear() method.
 Make some of PhyRegAlloc's reference members into pointer members,
  so they can be more easily messed with.
 Add prototype for markAllocatedRegs().
 Remove unused inline void constructLiveRanges().

    machine-specific code for allocation.
(3) Rename TargetRegInfo::getRegType variants to avoid unintentional

llvm-svn: 7153
 2003-07-10 19:43:33 +00:00
Vikram S. Adve 5224b19deb Several fixes to handling of int CC register: 
(1) An int CC live range must be spilled if there are any interferences,
    even if no other "neighbour" in the interf. graph has been allocated
    that reg. yet.  This is actually true of any class with only one reg!

(2) SparcIntCCRegClass::colorIGNode sets the color even if the LR must
    be spilled so that the machine-independent spill code doesn't have to
    make the machine-dependent decision of which CC name to use based on
    operand type: %xcc or %icc.  (These are two halves of the same
register.)

(3) LR->isMarkedForSpill() is no longer the same as LR->hasColor().
    These should never have been the same, and this is necessary now for #2.

(4) All RDCCR and WRCCR instructions are directly generated with the
    phony number for %ccr so that EmitAssembly/EmitBinary doesn't have to
    deal with this.

Misha Brukman 366494ab0d Do not hastily change the Opcode from 'r' to 'i' type if we're not actually 
SETTING the operand to be an immediate or have verified that one of the operands
is really a SignExtended or Unextended immediate value already, which warrants
an 'i' opcode.

llvm-svn: 6624
 2003-06-05 17:15:04 +00:00
Misha Brukman 4e7bad01ff I have finally seen the light. The code to change the opcode must live higher in 
the loop, and in both cases. In the first case, it is a VReg that is a constant
so it may be actually converted to a constant. In the second case, it is already
a constant, but then if it doesn't change its type (e.g. to become a register
and have the value loaded from memory if it is too large to live in its
instruction field), we must change the opcode BEFORE the 'continue', otherwise
we miss the opportunity.
