Direct assignments to env during translation do not work.
As it happens, the only way we can get here is if env->pc
is already set to dc->pc.
More to the point, t_gen_helper_raise_exception() does
tcg_gen_movi_tl(dc->cpu_R[R_PC], dc->pc);
before raising the exception (as you would expect it to).
Ah, didn't notice that. My comment works from the other direction:
Within the page, 0x1000-0x1fff, any insn executed will raise the 0xaa exception, which
means pc will be set for that insn.
