Subject: Rename 'descr' field in regset structure to 'regmap'.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=7fefa8d7d6359ec905dbc59bb4e616f386ea2e3d;p=binutils-gdb.git

Rename 'descr' field in regset structure to 'regmap'.

The regset structure's 'descr' field is intended to represent some
kind of "register map".  Thus, before making more use of it, this
change renames it to 'regmap' and adjusts the comment appropriately.

(See: https://sourceware.org/ml/gdb-patches/2014-05/msg00664.html)
