[PATCH v2 4/8] Move make_gdb_type functions within file

Alan Hayward
2018-01-24T09:28:43Z

This patch moves the function bodies for the various make_gdb_type
functions outside of the class declaration.
It doesn't not change any functionality and produces the same binary.

In the next patch I will move the class declarations to a different
file. This patch makes the diff of the next patch easier to read.

Alan.
