Hi John Reiser,
Thank you for your reply.
To be more specific, here is my target device spec:
*Processor : ARM926EJ-S rev 5 (v5l) BogoMIPS : 119.19 Features : swp half
thumb fastmult edsp java CPU implementer : 0x41 CPU architecture: 5TEJ CPU
variant : 0x0 CPU part : 0x926 CPU revision : 5 *
Since it uses ARM926EJ-S processor, in an attempt to fix *error: bad value
(cortex-a8) for -mcpu= switch,* I replace cortex-a8 with arm926ej-s for all
files in valgrind-3.13.0 folder. I am able to bypass this error but another
error pops up:
m_dispatch/dispatch-arm-linux.S: Assembler messages:
m_dispatch/dispatch-arm-linux.S:104: Error: selected processor does
not support `movw r1,#47'
m_dispatch/dispatch-arm-linux.S:105: Error: selected processor does

Makefile:3224: recipe for target
'm_dispatch/libcoregrind_arm_linux_a-dispatch-arm-linux.o' faile
So i tried your suggestion, which is "Delete the -mcpu entirely".
Another error pops up:
m_dispatch/dispatch-arm-linux.S: Assembler messages:

I desperately need a tool to check memory leak for binary file on my
device. Is there any workaround for this?
