Subject: target/ppc: Set OV32 when OV is set
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=af721a31696a1e08d8dcdabcd14c4cb09f9a5e16;p=qemu.git

target/ppc: Set OV32 when OV is set

According to PowerISA: "OV32 is set whenever OV is implicitly set, and
is set to the same value that OV is defined to be set to in 32-bit
mode".

This patch changes helper_update_ov_legacy to set/clear ov32 when
applicable.
