[cfe-dev] Use clang tool to do template instantiation

[Hongbin Zheng via cfe-dev]

Hi fe-dev,

Recently I am looking to use clang tool to do template instantiation based
on some command line parameter.

E.g.  given template

template<int N>
static int f(int a) { return a + N; }

by providing the name of function and the list of template parameter, i.e.
f and 4 for the tool, the tool should generate the following cpp file:

template<int N>
static int f(int a) { return a + N; }

static int f_4(int a) { return a + 4; }

Is there any example in clang?
which part of clang I should look at?

Thanks
Hongbin
