Ah, hreset_excp_prefix vs excp_prefix. My bad. I was thinking of excp_prefix.

The SPR I was thinking of was HIOR:

static void spr_write_hior (void *opaque, int sprn, int gprn)
{
    TCGv t0 = tcg_temp_new();
    tcg_gen_andi_tl(t0, cpu_gpr[gprn], 0x3FFFFF00000ULL);
    tcg_gen_st_tl(t0, cpu_env, offsetof(CPUPPCState, excp_prefix));
    tcg_temp_free(t0);
}
