Hi
I want to look into the register value when register is ready in rename
stage.
What can I do for it?
Specifically, I want to check the register value at line number 1022 in
file src/cpu/o3/rename_impl.hh.
Thanks,
Ed
file src/cpu/o3/rename_impl.hh
973 template <class Impl>
974 inline void
975 DefaultRename<Impl>::renameSrcRegs(DynInstPtr &inst, ThreadID tid)
976 {
977 assert(renameMap[tid] != 0);
978
979 unsigned num_src_regs = inst->numSrcRegs();
980
981 // Get the architectual register numbers from the source and
982 // destination operands, and redirect them to the right
register.
983 // Will need to mark dependencies though.
984 for (int src_idx = 0; src_idx < num_src_regs; src_idx++) {
985 RegIndex src_reg = inst->srcRegIdx(src_idx);
.......
.......
1006 inst->flattenSrcReg(src_idx, flat_src_reg);
1007
1008 // Look up the source registers to get the phys. register
they've
1009 // been renamed to, and set the sources to those registers.
1010 PhysRegIndex renamed_reg =
renameMap[tid]->lookup(flat_src_reg);
1011
1012 DPRINTF(Rename, "[tid:%u]: Looking up arch reg %i, got "
1013 "physical reg %i.\n", tid, (int)flat_src_reg,
1014 (int)renamed_reg);
1015
1016 inst->renameSrcReg(src_idx, renamed_reg);
1017
1018 // See if the register is ready or not.
1019 if (scoreboard->getReg(renamed_reg) == true) {
1020 DPRINTF(Rename, "[tid:%u]: Register %d is ready.\n",
1021 tid, renamed_reg);
1022 /* ================== looking into the register value here
================= */
1023 inst->markSrcRegReady(src_idx);
1024 } else {
1025 DPRINTF(Rename, "[tid:%u]: Register %d is not ready.\n",
1026 tid, renamed_reg);
1027 }
