Subject: [PATCH] target/ppc: Set OV32 when OV is set
|
||
|

Content-Type: text/plain; charset=UTF-8

|
|
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.
