fix smul and sdiv to sign extend, and handle overflow/underflow corretly
Only allow writing/reading of 32 bits of Y Only allow writing/reading 32 bits of pc when pstate.am Put any loaded data on the first half of a micro-op in uReg0 so it can't overwrite the register we are using for address calculation only erase a entry from the lookup table if it's valid Put in a temporary check to make sure that lookup table and tlb array stay in sync if we are interrupted in the middle of a mico-op, reset the micropc/nexpc so we start on the first part of it when we come back src/arch/sparc/isa/decoder.isa: fix smul and sdiv to sign extend, and handle overflow/underflow corretly Only allow writing/reading of 32 bits of Y Only allow writing/reading 32 bits of pc when pstate.am Put any loaded data on the first half of a micro-op in uReg0 so it can't overwrite the register we are using for address calculation src/arch/sparc/isa/formats/mem/blockmem.isa: Put any loaded data on the first half of a micro-op in uReg0 so it can't overwrite the register we are using for address calculation src/arch/sparc/isa/includes.isa: Use limits for 32bit underflow/overflow detection src/arch/sparc/tlb.cc: only erase a entry from the lookup table if it's valid Put in a temporary check to make sure that lookup table and tlb array stay in sync src/arch/sparc/tlb_map.hh: add a print function to dump the tlb lookup table src/cpu/simple/base.cc: if we are interrupted in the middle of a mico-op, reset the micropc/nexpc so we start on the first part of it when we come back --HG-- extra : convert_revision : 50a23837fd888393a5c2aa35cbd1abeebb7f55d4
