Hi,
Here are the 2nd version of fix bugs in process_fetch_insn_*(). The previous version is here;
https://lore.kernel.org/all/168830922841.2278819.9165254236027770818.stgit@mhiramat.roam.corp.google.com/
The first patch [1/4] just updated the description. [2/4] has been changed because previous one did not consider to store the array data. So instead of exit, just clear the 'ret' if it has any error code. [3/4] reverts the patch which did not work. And [4/4] makes each fetch_store_string*() always updates the data_loc, instead of clearing it in store_trace_args().
Thank you,
---
