From 09748966c1b65c953971f8e56d7f6113cfbfda95 Mon Sep 17 00:00:00 2001 From: Walfred Tedeschi Date: Wed, 20 Nov 2013 13:03:07 +0100 Subject: Add pretty-printer for MPX bnd registers. Boundary length is simpler implemented by means of a pretty printer. This simplifies users life when examining a bound register. Changelog: 2013-11-20 Walfred Tedeschi * python/lib/gdb/command/bound_register.py: New file. * gdb/data-directory/Makefile.in: copy bond_register.py to the right path to be initialized at gdb startup. testsuite/ * gdb.python/py-pp-maint.exp: Consider new pretty-print added for registers.
