CRIS: Slight performance improvement for flag evaluation.

Translate sub and cmp ops separately when evaluating flags to avoid checking
for them at runtime.

  • break 8 sets ERP to the current insn.
  • First shot at S flag single-stepping.
  • Make it easier to use the local disasm.

CRIS: Improve ASID related TLB flushes.

  • Speedup and correct ASID (PID) related TLB flushes.

cf1d97f0 05/13/2008 01:59 pm edgar_igl CRIS: Improve TLB management and handle delayslots at page boundaries.
  • Dont flush the entire qemu tlb when the $pid changes. Instead we go through
    the guests TLB and choose entries that need to be flushed.
  • Add env->dslot and handle delayslots at pageboundaries....
dceaf394 05/07/2008 06:24 pm edgar_igl CRIS: More TCG conversion.
  • Convert moves to/from support function regs (including TLB updates) to TCG.
  • SCC no longer requires T0 to strictly be 0 or 1, relaxed to 0 or non-zero.
  • Convert the the condition code evaluation to TCG.
  • Convert rfe into a helper and TCG....
b41f7df0 05/03/2008 01:16 am edgar_igl CRIS updates:
  • Support both the I and D MMUs and improve the accuracy of the MMU model.
  • Handle the automatic user/kernel stack pointer switching when leaving or entering user mode.
  • Move the CCS evaluation into helper funcs.
  • Make sure user-mode cannot change flags only writeable in kernel mode....
