Performance measurement of a C program on Raspberry Pi

Question

My C program (a simple PolarSSL client) runs on a Raspberry Pi. I want to measure the RAM usage and CPU timings of this client. Valgrind doesn't work on the Raspberry Pi. Instead it throws the following exception:

==3199== valgrind: Unrecognised instruction at address 0x4843588.
==3199==    at 0x4843588: ??? (in /usr/lib/arm-linux-gnueabihf/libcofi_rpi.so)

From what I gather, this exception is a well known problem of Valgrind on the Raspberry.

What can I do to solve this problem?

As far as performance goes, oprofile might help you. It needs some work to set up though (kernel modules).
