(bfin_expand_epilogue): Ask do_unlink to restore FP and RETS
with saveall attribute.
+ * config/bfin/bfin.c (bfin_expand_builtin,
+ case BFIN_BUILTIN_MULT_1X32X32): Force constants to registers for the
+ operands.
+ From Jie Zhang <jie.zhang@analog.com>:
+ * config/bfin/bfin.c (bfin_expand_builtin): Initialize icodes
+ before use in two places.
+ * config/bfin/bfin.md (AREG): Define mode iterator.
+ (reload_in, reload_out): Use mode iterator AREG.
