Drop the unused dest argument to gen_jr().
Remove most of the calls to gen_jr, and use DISAS_JUMP.
Remove some unused loads of eip for lcall and ljmp.
The only use outside i386_tr_tb_stop is here:
static void gen_goto_tb(DisasContext *s, int tb_num, target_ulong eip)
{
target_ulong pc = s->cs_base + eip;
if (translator_use_goto_tb(&s->base, pc)) {
/* jump to same page: we can use a direct jump */
tcg_gen_goto_tb(tb_num);
gen_jmp_im(s, eip);
tcg_gen_exit_tb(s->base.tb, tb_num);
s->base.is_jmp = DISAS_NORETURN;
} else {
/* jump to another page */
gen_jmp_im(s, eip);
gen_jr(s);
}
}
Should it set s->base.is_jmp = DISAS_JUMP instead, so that gen_jr() can be
inlined into i386_tr_tb_stop() and removed completely? If not,
