Hi all,
I'm trying to take checkpoints from SimPoints for SPEC CPU 2017 in SE
mode. I would like to generate checkpoints for different ISAs (RISCV and
X86).
So far, I did the following:
1) BBV files created using "qpoints" tool
(https://github.com/pranith/qpoints), since "--simpoint-profile", from
se.py, was taking too long.
2) For the SimPoints, I used the tool from UCSD
(https://cseweb.ucsd.edu/~calder/simpoint/).
3) For the checkpoint generation I used the "--take-simpoint-checkpoint"
option from se.py.
With RISCV I had no problem to take checkpoints for all the benchmarks
of IntRate suite (apart from 502.gcc_r).
On the other hand, using X86 I am not able to run several benchmarks of
IntRate suite. In particular, the benchmarks that give me problems are:
* 500.perlbench_r
* 502.gcc_r
* 520.omnetpp_r
* 523.xalancbmk_r
* 557.xz_r
I noticed that all the benchmarks that fail with X86 display the
following warning several times:
"build/X86/arch/x86/generated/exec-ns.cc.inc:27: warn: instruction
'palignr_Vdq_Wdq_Ib' unimplemented"
Any hints on how to solve this? Is there a solution other than
implementing the "palignr" instruction
I am using the last stable version of gem5 (v22.1, commit 5fa484e)
Thanks in advance,
Mirco
