Applies to the F version as well, but we should not assemble src2 when
we don't need it.
OK, I'll fix this.
- tcg_gen_mov_i64(cpu_fpr[a->rd], cpu_fpr[a->rs1]);
+ tcg_gen_mov_i64(dest, src1);
I think this can just be dest = get_fpr_d(ctx, a->src1), leaving the
final "move" to gen_set_fpr_d.
OK. I'll update this.
