Simple question related to modifying a GCC pass

[Sandeep K Chaudhary]

Hi guys,

If I make some modification to a gcc pass (tree-ssa-ccp.c for
example), is it possible to only build this pass, and load it (the
shared lib) while invoking gcc?

I mean, is it possible to be able to make this kind of modification,
and use the executables without having to build gcc from source? The
same way a custom written GIMPLE pass is built and loaded.

Thanks and regards,
Sandeep.
