I should have probably mentioned somewhere that this patch also fixes a resource leak in that function. It is not very obvious when looking at it as a patch, but if you take a look at the original code, you will see that I removed these allocations on purpose: https://github.com/qemu/qemu/blob/d577dbaac7553767232faabb6a3e291aebd348ae/target/ppc/translate/spe-impl.inc.c#L532 > static inline void gen_evmwsmiaa(DisasContext *ctx) > { > TCGv_i64 acc = tcg_temp_new_i64(); > TCGv_i64 tmp = tcg_temp_new_i64(); > > gen_evmwsmi(ctx); /* rD := rA * rB */ > > acc = tcg_temp_new_i64(); > tmp = tcg_temp_new_i64(); I apologize for not making this any more clear in my description. Let me know if this looks correct now, with the full context in mind. Thanks.
