Hi all??
About a few months ago, I followed the guidelines of this link to
successfully build M5ops??
https://www.gem5.org/documentation/general_docs/m5ops/
Now I am still using gem5-20.0 and have not updated to the new
version, but when I run this command again:
scons build/X86/out/m5
I received a bug report, the following is the complete content:
/********************************************************/
Warning: Your compiler doesn't support incremental linking and lto at the same
time, so lto is being disabled. To force lto
on anyway, use the
--force-lto option. That will disable partial
linking.
