I think I may have found the culprit - athlon is defined as
'PPRO_FEATURES + some additional features'.
If PPRO_FEATURES is what I think it is (pentium pro) why does it have
SSE and SSE2 defined? It should end with MMX.

Title:
qemu-i386 pentium3/athlon incorrect instruction set
Status in QEMU:
Won't Fix
Bug description:
Running a binary containing a movsd instruction (SSE2) in 32-bit
qemu-i386 from 20150609 using the -cpu pentium3 switch results in
flawless execution whereas it should crash with SIGILL as P3 only had
SSE and not SSE2.
