Subject: gdb: make-target-delegates.py: add Entry type
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=c6cf3ced973b8fea7d45c0f751cf9724a6a6e5b7;p=binutils-gdb.git

gdb: make-target-delegates.py: add Entry type

Add the Entry type and use it in the `entries` map, rather than using an
ad-hoc str -> str map that comes from the re.match.  This will make it
easier to make typing work in a subsequent patch, but it also helps
readers know what attributes exist for entries, which is not clear
currently.
