Changed paths:
M proccontrol/src/linux.C
Log Message:
-----------
In ProccontrolAPI, adding reading & writing mutatee's memory with procfs.
We fall back to use ptrace if procfs read & write fail.
This change is for fixing icache coherence issue for ARM dynamic
instrumentaiton.
ARM architecture does not guarantee icache-dcache coherence. And writes through
ptrace does not seem to invalidate icache contents and caused SIGILLs
