In this patch, I also comment out some syscalls which isn't handled by GDB now. With this patch applied, two fails are fixed. -FAIL: gdb.reverse/fstatat-reverse.exp: continue to breakpoint: marker2 -FAIL: gdb.reverse/recvmsg-reverse.exp: continue to breakpoint: marker2 gdb: 2016-03-17 Yao Qi * arm-linux-tdep.c (arm_canonicalize_syscall): Canonicalize more syscalls. --- gdb/arm-linux-tdep.c | 375 +++++++++++++++++++++++++++++++++++++++++++++++++-- 1 file changed, 365 insertions(+), 10 deletions(-) diff --git a/gdb/arm-linux-tdep.c b/gdb/arm-linux-tdep.c index 22f2aca..9b68315 100644 --- a/gdb/arm-linux-tdep.c +++ b/gdb/arm-linux-tdep.c @@ -1283,16 +1283,371 @@ struct linux_record_tdep arm_linux_record_tdep;
