/* Add any extra modes needed to represent the condition code.
|
||
|
|
||
|
On the Visium, we have a "no-overflow" mode which is used when arithmetic
|
||
|
instructions set the condition code. Different branches are used in this
|
||
|
case for some operations.
|
||
|
|
||
|
We also have a "bit-test" mode which is used when the bit-test instruction
|
||
|
sets the condition code.
|
||
|
|
||
|
We also have two modes to indicate that the condition code is set by the
|
||
|
the floating-point unit. One for comparisons which generate an exception
|
||
|
if the result is unordered (CCFPEmode) and one for comparisons which never
|
||
|
generate such an exception (CCFPmode). */
