I'm using perf 3.19.0 on Archlinux
[arch@t440s-arch ~/Trash]$ uname -a
Linux t440s-arch 3.18.6-1-ARCH #1 SMP PREEMPT Sat Feb 7 08:44:05 CET
2015 x86_64 GNU/Linux
Recently after updating perf package, I found the 'ip' in 'perf
script' like below is shorter than before. Also feeding that address
(like 57e below) to addr2line does not output filename:lineno
information anymore. How do I fix this issue? Is this a bug?
a.out 26620 [000] 314643.350007: 6825289 cycles:
57e main (/home/arch/Trash/a.out)
20800 __libc_start_main (/usr/lib/libc-2.21.so)
13d6258d4c544155 [unknown] ([unknown])
thank you,
Yuanfang
