I really wonder if we should simply move the tcg_gen_concat_i64_i128() into the op and use
a generic "allocate out_128" instead.
At least that part here confused me heavily.
Just the prep_r1_D64 bit of it?
Better for you as
C(0xeb3e, CDSG, RSY_a, Z, la2, r3_D64, 0, r1_D64, cdsg, 0)
static DisasJumpType op_cdsg(DisasContext *s, DisasOps *o)
{
int r1 = get_field(s, r1);
+ o->out_128 = tcg_temp_new_i128();
+ tcg_gen_concat_i64_i128(o->out_128, regs[r1 + 1], regs[r1]);
The existing generic "allocate out_128" is named "new_x", which I thought was also
confusing, since this isn't an "x" format operation. Since there's only one use, I did it
inline.
