Hi,
I'm trying to use perf record/report on a non-stripped, Haskell binary
(i.e. compiled using GHC). Unfortunately, not all symbols are
decoded*:
75.28% bench ./bench [.] 0x000000002b612b
7.11% bench /lib/libc-2.11.1.so [.] memcpy
5.47% bench ./bench [.] 0x0000000000438f
3.47% bench ./bench [.] allocate
1.86% bench ./bench [.] s1Ol_info
1.65% bench ./bench [.] s1Ok_info
0.62% bench ./bench [.] memcpy@plt
0.48% bench ./bench [.] clearNurseries
0.33% bench ./bench [.] evacuate1
0.24% bench ./bench [.] GarbageCollect
How can I figure out what 0x000000002b612b corresponds to?
perf version: 0.0.2.PERF (installed from Ubuntu package)
Kernel version: 2.6.32
$ cat /proc/cpuinfo
processor : 0
vendor_id : GenuineIntel
cpu family : 6
model : 44
model name : Intel(R) Xeon(R) CPU X5650 @ 2.67GHz
* It could be the case that GHC is generating symbols that perf cannot
interpret somehow. If we can confirm this is the case we can try to
fix that.
