/* Add any extra modes needed to represent the condition code.
|
|
|
|
We have a CCNZ mode which is used for implicit comparisons with zero when
|
|
arithmetic instructions set the condition code. Only the N and Z flags
|
|
are valid in this mode, which means that only the =,!= and <,>= operators
|
|
can be used in conjunction with it.
|
|
|
|
We also have a CCCmode which is used by the arithmetic instructions when
|
|
they explicitly set the C flag (unsigned overflow). Only the unsigned
|
|
<,>= operators can be used in conjunction with it.
|
|
|
|
We also have a CCVmode which is used by the arithmetic instructions when
|
|
they explicitly set the V flag (signed overflow). Only the =,!= operators
|
|
can be used in conjunction with it.
|
|
|
|
We also have two modes to indicate that the relevant condition code is
|
|
in the floating-point condition code register. One for comparisons which
|
|
will generate an exception if the result is unordered (CCFPEmode) and
|
|
one for comparisons which will never trap (CCFPmode).
|
|
|
|
CC modes are used for the 32-bit ICC, CCX modes for the 64-bit XCC. */
