I am new to GCC internals.
I'm trying to create a plugin to operate on pragmas. Currently have
this working using c_register_pragma with a callback.
The callback performs pragma_lex and is able to retrieve the string
token of the pragma based on this example.
https://github.com/wh5a/gcc-plugin/blob/master/pragma_plugin.c
How can I determine the line number of the pragma? I tried
DECL_SOURCE_LINE on the tree type but this returns 0. Do I have to
interact with cpplib?

Vanush
