Subject: [PATCH] Process record for aarch64-linux syscall
Date: Tue, 23 Feb 2016 09:19:00 -0000 [thread overview]
Message-ID: <1456219131-2781-1-git-send-email-yao.qi@linaro.org> (raw)
This patch updates the syscalls in sync with syscalls/aarch64-linux.xml.
Some syscalls are still not supported by gdb/linux-record.c yet. Mark
them UNSUPPORTED_SYSCALL_MAP.
This patch fixes the following test fail,
Process record and replay target doesn't support syscall number 56^M
Process record: failed to record execution log.^M
^M
Program stopped.^M
0x00000020000e9dfc in open () from /lib/aarch64-linux-gnu/libc.so.6^M
(gdb) FAIL: gdb.reverse/fstatat-reverse.exp: continue to breakpoint: marker2
I'll push it in.
