Subject: Remove redundant assignment from dwarf2_find_containing_comp_unit
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=82cb27ff6b4e1ae811e72a02dddc3db4c9ff97b8;p=binutils-gdb.git

Remove redundant assignment from dwarf2_find_containing_comp_unit

dwarf2_find_containing_comp_unit has two assignments to "this_cu" in
quick succession, both of which are just:

  this_cu = dwarf2_per_objfile->all_comp_units[low];

... with no intervening assignments.

This patch removes the second assignment.  I'm checking this in as
obvious.  Tested on x86-64 Fedora 29.
