From d521906965b3e94648a723a13576236aaba301d0 Mon Sep 17 00:00:00 2001 From: Yao Qi Date: Fri, 19 Feb 2016 15:54:03 +0000 Subject: [PATCH] aarch64-linux process record: more syscalls The last patch supports several syscalls in linux-record.c, so now GDB aarch64-linux backend can return these canonicalized syscall numbers per aarch64 syscall number. This patch fixes the following fails, Process record and replay target doesn't support syscall number 59^M Process record: failed to record execution log.^M ^M Program stopped.^M 0x00000020000eab28 in pipe () from /lib/aarch64-linux-gnu/libc.so.6^M (gdb) FAIL: gdb.reverse/pipe-reverse.exp: continue to breakpoint: marker2 Process record and replay target doesn't support syscall number 59^M Process record: failed to record execution log.^M ^M Program stopped.^M 0x00000020000eab28 in pipe () from /lib/aarch64-linux-gnu/libc.so.6^M (gdb) FAIL: gdb.reverse/readv-reverse.exp: continue to breakpoint: marker2 gdb: 2016-02-29 Yao Qi * aarch64-linux-tdep.c (aarch64_canonicalize_syscall): Support eventfd2, eventfd2, dup3, inotify_init1, fallocate and pipe2.
