HI Tariq,

You can fix it and submit a patch to gerrit :). Likely, you just need
#include  at the top of addr_range_map.hh.

See https://gem5.googlesource.com/public/gem5/+/master/CONTRIBUTING.md for
more details.

Cheers,
Jason

[gem5-users] Error when building gem5

[Tariq Azmy]

Hi,

I got a fresh new gem5 from google repo (
https://gem5.googlesource.com/public/gem5) and built the X86 with scons.
But there's an error from xbar:

In file included from build/X86/mem/xbar.hh:57:0,
 from build/X86/mem/noncoherent_xbar.hh:54,
 from build/X86/mem/noncoherent_xbar.cc:50:

been declared
 find(const AddrRange , std::function cond)
const
   ^~~~
build/X86/base/addr_range_map.hh:221:43: error: expected ',' or '...'
before '<' token
 find(const AddrRange , std::function cond)
const
   ^
scons: *** [build/X86/mem/noncoherent_xbar.o] Error 1
scons: building terminated because of errors.

Hope it can get fixed.

Thanks

[gem5-users] Functional Models for ALU

[Riddhi Thakker]

Hi all,

I am looking for the functional units of the ALU for X86 system. I noticed
that there is a class IntAlu, IntMult, IntDiv, and so on (in file
src/cpu/o3/FuncUnitConfig.py). But I could not figure out where the add
instruction for ALU, and other sub, mul instructions are defined.

Can anyone please help me how should I proceed further.

Thanks in advance.

Regards,
Riddhi
