Hi,

I'd like to replace some code in the binary, currently

I can do function level replacement using Dyninst API's

replaceFunction. Is there any way in Dyninst or other APIs
to do code replacement at a smaller granularity? say at loop
level or basic block level?

Dyninst no, PatchAPI yes, not for the faint of heart, semi-frequently asked question; check the archives re: binary modification for more detailed answers (I need to run now).

Are you sure that *replacement* is precisely what you want?

Thank you very much!
