21/* 32-bit signed int remainder. This is not a normal C function. Argument
22 registers are t10 and t11, the result goes in t12. Only t12 and AT may
23 be clobbered.
24
25 The FPU can handle the division for all input values except zero.
26 All we have to do is compute the remainder via multiply-and-subtract.
27
28 The FPCR save/restore is due to the fact that the EV6 _will_ set FPCR_INE
29 for cvttq/c even without /sui being set. It will not, however, properly
30 raise the exception, so we don't have to worry about FPCR_INED being clear
31 and so dying by SIGFPE. */
