(earith, etrunci, etruncui, ereal_negate, ereal_ldexp, real_value_truncate, esub, eadd, emul, ediv, eremain): Return NaN arg back to caller. (eroundi, eroundui, ereal_to_int): NaN to integer returns -1 and a warning. (target_isnan): Check for NaN. (eneg): No-op if NaN. (eisneg, eisinf): False if NaN. (emovi, emovo): Handle NaN conversions. (esub, eadd): Infinity minus infinity = NaN and INVALID warning. (ediv): 0/0, inf/inf = NaN and INVALID warning. (emul): 0 * inf = NaN and INVALID warning. (e24toe, e53toe, e64toe): Generate e-type NaN for NaN input. (etoe24, etoe53, etoe64): Output NaN in appropriate machine mode. (ecmp): Unordered compare returns -2. (etoasc): NaN produces ASCII string "NaN". (asctoe): Unrecognizable input produces e-type NaN. (eremain): x REM y = NaN if y = 0 or x = infinity. From-SVN: r4401
