The QEMU project is currently considering to move its bug tracking to
another system. For this we need to know which bugs are still valid
and which could be closed already. Thus we are setting older bugs to
"Incomplete" now.
If you still think this bug report here is valid, then please switch
the state back to "New" within the next 60 days, otherwise this report
will be marked as "Expired". Or please mark it as "Fix Released" if
the problem has been solved with a newer version of QEMU already.
Thank you and sorry for the inconvenience.
** Changed in: qemu
Status: New => Incomplete

Title:
qemu64 CPU model is incorrect
Status in QEMU:
Incomplete
Bug description:
At the moment the "qemu64" CPU is defined as follows:
```
.vendor = CPUID_VENDOR_AMD,
.family = 6,
.model = 6,
.stepping = 3,
```
According to Wikipedia [1] this means the CPU is defined as part of the
K7 family while the AMD64 ISA was only introduced with the K8 series!
This causes some software such as LLVM to notice the problem (32-bit cpu
with 64-bit capability reported in the cpuid flag) and produce various
error messages.
The simple solution would be to upgrade this definition to use the
Sledgehammer
family (15) instead.
