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