Changes to put all the misc regs within the misc reg file. This includes the FPCR, Uniq, lock flag, lock addr, and IPRs.
They are now accessed by calling readMiscReg()/setMiscReg() on the XC. Old IPR accesses are supported by using readMiscRegWithEffect() and setMiscRegWithEffect() (names may change in the future).
arch/alpha/alpha_memory.cc:
Change accesses to IPR to go through the XC.
arch/alpha/ev5.cc:
Change accesses for IPRs to go through the misc regs.
arch/alpha/isa/decoder.isa:
Change accesses to IPRs to go through the misc regs. readIpr() and setIpr() are now changed to calls to readMiscRegWithEffect() and setMiscRegWithEffect().
arch/alpha/isa/fp.isa:
Change accesses to IPRs and Fpcr to go through the misc regs.
arch/alpha/isa/main.isa:
Add support for all misc regs being accessed through readMiscReg() and setMiscReg(). Instead of readUniq and readFpcr, they are replaced by calls with Uniq_DepTag and Fpcr_DepTag passed in as the register index.
arch/alpha/isa_traits.hh:
Change the MiscRegFile to a class that handles all accesses to MiscRegs, which in Alpha include the FPCR, Uniq, Lock Addr, Lock Flag, and IPRs.
Two flavors of accesses are supported: normal register reads/writes, and reads/writes with effect. The latter are basically the original read/write IPR functions, while the former are normal reads/writes.
The lock flag and lock addr registers are added to the dependence tags in order to support being accessed through the misc regs.
arch/alpha/stacktrace.cc:
cpu/simple/cpu.cc:
dev/sinic.cc:
Change accesses to the IPRs to go through the XC.
arch/alpha/vtophys.cc:
Change access to the IPR to go through the XC.
arch/isa_parser.py:
Change generation of code for control registers to use the readMiscReg and setMiscReg functions.
base/remote_gdb.cc:
Change accesses to the IPR to go through the XC.
cpu/exec_context.hh:
Use the miscRegs to access the lock addr, lock flag, and other misc registers.
cpu/o3/alpha_cpu.hh:
cpu/simple/cpu.hh:
Support interface for reading and writing misc registers, which replaces readUniq, readFpcr, readIpr, and their set functions.
cpu/o3/alpha_cpu_impl.hh:
Change accesses to the IPRs to go through the miscRegs.
For now comment out some of the accesses to the misc regs until the proxy exec context is completed.
cpu/o3/alpha_dyn_inst.hh:
Change accesses to misc regs to use readMiscReg and setMiscReg.
cpu/o3/alpha_dyn_inst_impl.hh:
Remove old misc reg accessors.
cpu/o3/cpu.cc:
Comment out old misc reg accesses until the proxy exec context is completed.
cpu/o3/cpu.hh:
Change accesses to the misc regs.
cpu/o3/regfile.hh:
Remove old access methods for the misc regs, replace them with readMiscReg and setMiscReg. They are dummy functions for now until the proxy exec context is completed.
kern/kernel_stats.cc:
kern/system_events.cc:
Have accesses to the IPRs go through the XC.
kern/tru64/tru64.hh:
Have accesses to the misc regs use the new access methods.
