From: Tom Tromey Date: Thu, 21 Nov 2019 00:04:22 +0000 (-0700) Subject: Restore parameter names in observable.h X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=012fc90932dae0347c03244807b975a57a8448c0;p=binutils-gdb.git Restore parameter names in observable.h Ages ago, when we switched observables to be templates, Joel asked me to restore the parameter names that were used in the old observer.texi. I've finally done this, putting the names into comments. I also updated the comments in this file to use the GNU metasyntactic variable convention as well. gdb/ChangeLog 2019-11-22 Tom Tromey * observable.h: Update comments.
