Different branches are 28 used in this case for some operations. 29 30 We also have two modes to indicate that the relevant condition code is 31 in the floating-point condition code register. One for comparisons which 32 will generate an exception if the result is unordered (CCFPEmode) and 33 one for comparisons which will never trap (CCFPmode). 34 35 CCXmode and CCX_NOOVmode are only used by v9. */ 36 37CC (CCX) 38CC (CC_NOOV) 39CC (CCX_NOOV) 40CC (CCFP) 41CC (CCFPE) 42 43
