How to characterize a workload by obtaining the instruction type breakdown?

I want to obtain the percentage of memory read-write instructions in a test program, preferably dynamically. Apart from counting instructions in the gdb asm dump, which is static anyway, is there an easier way to obtain it? Valgrind provides total…
