Subject: [PATCH v2 26/41] target/hppa: Make hppa_cpu_tlb_fill sysemu only
Date: Sat, 18 Sep 2021 11:45:12 -0700 [thread overview]
Message-ID: <20210918184527.408540-27-richard.henderson@linaro.org> (raw)
In-Reply-To: <20210918184527.408540-1-richard.henderson@linaro.org>
The fallback code in raise_sigsegv is sufficient for hppa-linux-user.
Remove the code from cpu_loop that raised SIGSEGV.
This makes all of the code in mem_helper.c sysemu only, so remove the
ifdefs and move the file to hppa_softmmu_ss.
Signed-off-by: Richard Henderson <richard.henderson@linaro.org>
