(1) Change the way unused regs. are marked and found to consider regType
...
info (since multiple reg types may share the same reg class).
(2) Remove machine-specific regalloc. methods that are no longer needed.
In particular, arguments and return value from a call do not need
machine-specific code for allocation.
(3) Rename TargetRegInfo::getRegType variants to avoid unintentional
overloading when an include file is omitted.

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.

(1) Added special register class containing (for now) %fsr.
...
Fixed spilling of %fcc[0-3] which are part of %fsr.
(2) Moved some machine-independent reg-class code to class TargetRegInfo
from SparcReg{Class,}Info.
(3) Renamed MachienOperand::opIsDef to MachineOperand::opIsDefOnly()
and related functions and flags. Fixed several bugs where only
"isDef" was being checked, not "isDefAndUse".
