Subject: Use std::string in execute_script_contents
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=a37a2ae7080898244de86d136961de81fe28a434;p=binutils-gdb.git

Use std::string in execute_script_contents

This changes execute_script_contents to use a std::string, allowing
the removal of a cleanup.

2018-02-09  Tom Tromey  <tom@tromey.com>

	* auto-load.c (execute_script_contents): Use std::string.
