Branch: refs/heads/pp_springboard Home: https://github.com/dyninst/dyninst Commit: ccb8b7236aff9c757b7cc53daa22969a69813666 https://github.com/dyninst/dyninst/commit/ccb8b7236aff9c757b7cc53daa22969a69813666 Author: Xiaozhu Meng <xmeng@xxxxxxxxxxx> Date: 2019-05-07 (Tue, 07 May 2019) 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 |
