Subject: [PATCH v2 48/74] target/m68k: Eliminate m68k_semi_is_fseek
Date: Tue,  3 May 2022 12:48:17 -0700	[thread overview]
Message-ID: <20220503194843.1379101-49-richard.henderson@linaro.org> (raw)
In-Reply-To: <20220503194843.1379101-1-richard.henderson@linaro.org>

Reorg m68k_semi_return_* to gdb_syscall_complete_cb.
Use the 32-bit version normally, and the 64-bit version
for HOSTED_LSEEK.
