+This section describes characteristics of debugging information that

@section Adding a New Symbol Reader to GDB
If you are using an existing object file format (a.out, COFF, ELF, etc),

accurately. The only way to make this work is to get accurate
information about the order that the compiler uses, and to reflect that

@item IS_TRAPPED_INTERNALVAR (name)
This is an ugly hook to allow the specification of special actions that
should occur as a side-effect of setting the value of a variable
internal to GDB. Currently only used by the h8500. Note that this
could be either a host or target conditional.
