[Qemu-devel] [PATCH 5/5] gdb: provide the name of the architecture in the target.xml |
Date: |

From: David Hildenbrand <address@hidden>
This patch provides the name of the architecture in the target.xml if available.
This allows the remote gdb to detect the target architecture on its own - so
there is no need to specify it manually (e.g. if gdb is started without a
binary) using "set arch *arch_name*".
The name of the architecture has been added to all archs that provide a
target.xml (by supplying a gdb_core_xml_file) and have a unique architecture
name in gdb's feature xml files.
