/* Add any extra modes needed to represent the condition code.
|
|
|
|
On the SPARC, we have a "no-overflow" mode which is used when an add or
|
|
subtract insn is used to set the condition code. Different branches are
|
|
used in this case for some operations.
|
|
|
|
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).
|
|
|
|
CCXmode and CCX_NOOVmode are only used by v9. */
