From: Simon Marchi Date: Fri, 15 Sep 2017 15:59:36 +0000 (+0200) Subject: Deduplicate require_running macros and move them up X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=f8a4e1192032044cdae544848865636f6e07a925;p=binutils-gdb.git Deduplicate require_running macros and move them up I find it very confusing to define the require_running in the middle of the file, and re-define it to something else later in the middle of the same file. I think it would be better if those macros had different names so that we know exactly what they do. gdb/gdbserver/ChangeLog: * server.c (require_running): Rename to ...
