If enabled, this option causes instructions to set the flag (`F'
|
|
bit) in the supervision register. The instructions affected by
|
|
this are `l.add', `l.addc', `l.addi', `l.and' and `l.andi'.

The default is for this to be disabled.

|
Caution: As with `--enable-ov-flag', this appears another
|
|
very dangerous option, to the extent of arguably being a bug.
|
|
It also appears to be only partially implemented--why only
|
|
the instructions early in the alphabet?
|
|
|
|
Whether or not flags are set is part of the OpenRISC 1000
|
|
architectural specification. The only flags which should set

this are the "set flag" instructions: `l.sfeq', `l.sfeqi',

`l.sfges', `l.sfgesi', `l.sfgeu', `l.sfgeui', `l.sfgts',

`l.sfgtsi', `l.sfgtu', `l.sfgtui', `l.sfles', `l.sflesi',

`l.sfleu', `l.sfleui', `l.sflts', `l.sfltsi', `l.sfltu',
|
|
`l.sfltui', `l.sfne' and `l.sfnei'.
|
|
|
|
The flags are correctly set (irrespective of
|
|
`--enable-arith_flag').
|
|
|
|
Correct behavior is thus achieved if this flag is not set.
|
|
`--enable-arith-flag' should never be used.
