Subject: [PATCH 16/46] [gdb/tdep] Handle syscall clock_gettime64 for arm-linux
|
|
|
|
When running test-case gdb.reverse/time-reverse.exp on arm-linux, I run into:
|
|
...
|
|
(gdb) continue^M
|
|
Continuing.^M
|
|
Process record and replay target doesn't support syscall number 403^M
|
|
Process record does not support instruction 0xdf00 at address 0xf7ebf774.^M
|
|
Process record: failed to record execution log.^M
|
|
^M
|
|
Program stopped.^M
|
|
0xf7ebf774 in ?? () from /lib/arm-linux-gnueabihf/libc.so.6^M
|
|
(gdb) FAIL: $exp: mode=c: continue to breakpoint: marker2
|
|
...
|
|
|
|
Syscall number 403 stands for clock_gettime64 on arm-linux.
|
|
|
|
Fix this by handling 403 in arm_canonicalize_syscall, and handling
|
|
gdb_sys_clock_gettime64 elsewhere.
|
|
|
|
Since i386_canonicalize_syscall is the identity function, enum value
|
|
gdb_sys_clock_gettime64 gets a value to match i386, which also happens to be
|
|
403.
|
|
|
|
Tested on arm-linux.
