[Qemu-devel] [Bug 1469342] Re: qemu-i386 pentium3 incorrect instruction set

[PeteVine]

Still there in the latest master.

To clarify, running the binary with the -cpu athlon switch (same
instruction set as P3) also exhibits the problem whereas a real athlon
SIGILL's correctly.

** Description changed:

  Running a binary containing a movsd instruction (SSE2) in 32-bit
- qemu-i386 -cpu pentium3 from 20150609 results in flawless execution
- whereas it should crash with SIGILL as P3 only had SSE.
+ 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.

** Summary changed:

- qemu-i386 pentium3 incorrect instruction set
+ qemu-i386 pentium3/athlon incorrect instruction set
