[ltt-dev] Can I use LTTng for auto-discovery of build dependencies?

[vesselin kavalov]

I am a consultant and constantly have to deal with new environments, where I 
have to build RTL netlists (and testbenches)? for simulation or synthesis or 
emulation and usually these involve thousands of files, most of which are passed 
to the corresponding EDA sw tools as search paths - in general - unknown till 
compile/run time of that tool.


I would like to be able to "snoop" on a flow and detect which executable uses 
which files as inputs/outputs and build the dependency tree, such that can be 
fed in some form to a make/make-like sw build tool for incremental compiles.

Most of the executables are just dynamically linked, stripped binaries, so I 
cannot compile them with some tracing beacon in them - gotta be something that 
runs on the side or creates a shell that intercepts syscalls like file open() 
etc.

Any help will be greatly appreciated!
Thanx
vess
