could I use opreport --symbols to analysis the log from arm target?

[Zhe X. <adr...@gm...>]

hi, I've used the opcontrol and opfiled to generate a log on my ARM board.
And I want to analysis this log on my host x86 machine.
Suppose my log got from ARM board is under folder "sample/" .I've already
used "opimport -a sample/abi xxx" to convert the log to my host binary
format.
Then I use "opreport -l --session-dir xxx --root xxx" to generate report.
"--root xxx" specify the path which contains all my arm binary files on ARM
board.
However, I find the result generated like this:

  197       0.1548  cg                       /bin/cg
  127036   99.8452  cg                       /bin/cg
84590    42.5084  libc-2.3.2.so            /lib/libc-2.3.2.so
  84590    66.4838  libc-2.3.2.so            /lib/libc-2.3.2.so
  39169    30.7850  libc-2.3.2.so          /lib/libc-2.3.2.s
  3475      2.7312  libc-2.3.2.so           /lib/libc-2.3.2.s

the symbol column shows the binary path not the symbol of binary. I
don't know the reason for that.
Could I use opreport that way? or opreport couldn't read arm binary
files correctly?
My oprofile version is 0.9.4

Thanks!
