When I create two vectors with different pointer types (e.g.
vector<char*> and vector<int*>), gcc compiles in two instances of vector
code. In SH architecture, it means cca. n * 10K of code, which is quite
big in our project.

The question is, can I somehow force the compiler to use the same code
for the two template instances?


If the object code generated for the two is really identical,
then if you really wanted to, you could write a whole-program
optimizer pass that combined them.

This is a topic for the gcc or libstdc++ mailing lists, though,
where people actually know something about this, so I'm redirecting there.
