gdb-10.2.patch | 12822 +++++++++++++++++++++++++++++++++++++++++-
This is really a big change for the gdb, there are 12822 lines of code.
:-) Is it possible to support the LoongArch64 feature if a very smaller
change is made in the gdb patch? For example: trying to remove
redundant(unnecessary) changes, as I mentioned in the V1.
Or is it hard to implement this feature based on the gdb-10.2? Looks
like all code changes are backported from the latest gdb?
Thanks
