[Valgrind-users] Clarification on functions in pub_tool_tooliface.h

[Mike L. <mik...@gm...>]

Being unable to search through gmane for now, I turn to the users group.

I'd like some clarification regarding some functions I'm seeing in the tool
interface.


   - track_new_mem_startup
   - ....
   - track_new_mem_mmap
   - ...
   - track_pre_mem_read
   - track_pre_mem_write
   - track_post_mem_write
   - track_post_reg_write

These callbacks specifically refer to events within the *core*, right? Does
this mean that they bear no relevance to profiling the user application?

Am I correct that a "mem_write" callback only gets called for memory write
that happens during translation, internal signal handling, etc, along with
the "new_mmap" calls? If I were to instrument the *application under test* then
I'd go through the callback given in "basic_tool_funcs", correct?

I only asks because I just noticed these functions, and the wording in the
comments wasn't incredibly clear.

Thanks,
Mike
