2017-07-26Use visitor pattern for "maint print c-tdesc"Yao Qi1-2/+2
Target description can be modeled as a tree, the target description is the root node, features are children nodes, registers and types are grand-children nodes. So command "maint print c-tdesc" in effect traverse/visit each node, and print them in c. This can be implemented by visitor pattern, this is the first reason. Secondly, I want to this command prints c files in a different way for some specific xml files, but still print c files the same way for the rest of xml files. Third, I even want to print xml files from target descriptions, so that GDBserver can use it to reply GDB's query qXfer:features:read:target.xml. gdb: 2017-07-26 Yao Qi <yao.qi@linaro.org> * target-descriptions.c (tdesc_element_visitor): New class.
