I had the same error. It seems a recent upgrade to GCC-11 cross compiler
from arm results in this error. The GCC-10 version would work.
Though not the culprit, I want to ask if there is a way to ensure to run
64-bit emulated process.
As I understand, ArmISA.py was not exposed into configuration files. So if
I don't change these py (which seems to require recompilation of gem5), I
will be running the default ArmISA in the SE simulation with following
features
class ArmDefaultSERelease(ArmRelease):
extensions = [
'CRYPTO',
# Armv8.1
'FEAT_LSE', 'FEAT_RDM',
# Armv8.2
'FEAT_SVE',
# Armv8.3
'FEAT_FCMA', 'FEAT_JSCVT', 'FEAT_PAuth',
# Other
'TME'
]
But is there control over AArch64 vs ARMv7 32bit? Is ARMv7 only existing in
older versions of Gem5?
Regards,
Chen
