Subject: [PATCH v4 16/28] cpu: Restrict "hw/core/sysemu-cpu-ops.h" to target/cpu.c
Date: Wed,  3 Mar 2021 22:46:56 +0100	[thread overview]
Message-ID: <20210303214708.1727801-17-f4bug@amsat.org> (raw)
In-Reply-To: <20210303214708.1727801-1-f4bug@amsat.org>

Somehow similar to commit 78271684719 ("cpu: tcg_ops: move to
tcg-cpu-ops.h, keep a pointer in CPUClass"):

We cannot in principle make the SysEmu Operations field definitions
conditional on CONFIG_SOFTMMU in code that is included by both
common_ss and specific_ss modules.

Therefore, what we can do safely to restrict the SysEmu fields to
system emulation builds, is to move all sysemu operations into a
separate header file, which is only included by system-specific code.

This leaves just a NULL pointer in the cpu.h for the user-mode builds.
