From: Tom Tromey Date: Thu, 26 Apr 2018 22:18:07 +0000 (-0600) Subject: Handle var_zuinteger and var_zuinteger_unlimited from Python X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=0489430a0e1a3ea302c22c540f3629e471591f23;p=binutils-gdb.git Handle var_zuinteger and var_zuinteger_unlimited from Python PR python/20084 points out that the Python API doesn't handle the var_zuinteger and var_zuinteger_unlimited parameter types. This patch adds support for these types. Regression tested on x86-64 Fedora 26.
