Subject: Remove last cleanups from solib-svr4.c
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=2b6ff1c0474fca286b95be7ae9dcc5a22ff2a0b9;p=binutils-gdb.git

Remove last cleanups from solib-svr4.c

This removes the last cleanups from solib-svr4.c, replacing them with
uses of make_scope_exit.

2019-03-06  Tom Tromey  <tom@tromey.com>

	* solib-svr4.c (svr4_parse_libraries, svr4_current_sos_direct):
	Use make_scope_exit.
