[PATCH v3 05/25] target/arm: Move the reference to arm-core.xml

Posted by Akihiko Odaki 2 years, 5 months ago

Some subclasses overwrite gdb_core_xml_file member but others don't.
Always initialize the member in the subclasses for consistency.

This especially helps for AArch64; in a following change, the file
specified by gdb_core_xml_file is always looked up even if it's going to
be overwritten later. Looking up arm-core.xml results in an error as
it will not be embedded in the AArch64 build.
