[Qemu-devel] [Bug 1283519] [NEW] PowerPC altivec rounding instructions vrfi(m|n|z)not correctly mapped

[Mathias Gaunard]

Public bug reported:

When using ppc-linux-user/qemu-ppc on a ppc ELF executable, I see that
QEMU wrongly recognizes the vrfim, vrfin and vrfiz instructions:

If the binary contains vrfim QEMU sees vrfiz
If the binary contains vrfin QEMU sees vrfim
If the binary contains vrfiz QEMU sees vrfin
The vrfip instruction is correctly recognized.

Those instructions normally round a floating-point altivec vector to
zero (z), infinity (p), minus infinity (m) or nearest (n).

** Affects: qemu
