Change MRegisterDesc::AliasSet, TargetInstrDescriptor::ImplicitDefs
...
and TargetInstrDescriptor::ImplicitUses to always point to a null
terminated array and never be null. So there is no need to check for
pointer validity when iterating over those sets. Code that looked
like:
if (const unsigned* AS = TID.ImplicitDefs) {
for (int i = 0; AS[i]; ++i) {
// use AS[i]
}
}
was changed to:
for (const unsigned* AS = TID.ImplicitDefs; *AS; ++AS) {
// use *AS
}

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().

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.

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.

Changes to allow explicit physical register arguments that have been
...
preallocated. While reg-to-reg dependences were already handled, this
change required new code for adding edges to/from call instructions.
This was part of the extensive changes to the way code generation occurs
for function call arguments and return values.
See log for CodeGen/PhyRegAlloc.cpp.

Extensive changes to the way code generation occurs for function
...
call arguments and return values:
Now all copy operations before and after a call are generated during
selection instead of during register allocation.
The values are copied to virtual registers (or to the stack), but
in the former case these operands are marked with the correct physical
registers according to the calling convention.
Although this complicates scheduling and does not work well with
live range analysis, it simplifies the machine-dependent part of
register allocation.

and related functions and flags. Fixed several bugs where only
"isDef" was being checked, not "isDefAndUse".

branches and returns explicitly.

This should fix the bug seen with some registers not being allocated
...
correctly: skipping instructions by incorrectly incrementing the pointer.
Also adds support for building a reg-to-regclass map, and splits the function
for saving register to stack into two, one suitable for virtual registers
(which also assigns it a physical register) and one for simply storing back
physical registers.
