Accessing Global variables

[zahed khurasani <sdzahed@xxxxxxxxx>]

Hi,

I know that we can access the function parameters using DECL_ARGUMENTS
and similary we can use gimple_bind_vars to access other variable
declarations attached to a bind expression. But how about Global
definitions? How can I access variables defined outside the scope of
any function.

Thanks for your help.
