From 9335d9f8235a13777ae058b1ad59f124b678f4fc Mon Sep 17 00:00:00 2001 From: Mike Frysinger Date: Thu, 8 Jul 2021 02:33:28 -0400 Subject: sim: rename ChangeLog files to ChangeLog-2021 Now that ChangeLog entries are no longer used for sim patches, this commit renames all relevant sim ChangeLog to ChangeLog-2021, similar to what we would do in the context of the "Start of New Year" procedure. The purpose of this change is to avoid people merging ChangeLog entries by mistake when applying existing commits that they are currently working on. Also throw in a .gitignore entry to keep people from adding new ChangeLog files anywhere in the sim tree. --- sim/frv/ChangeLog | 3368 ------------------------------------------------ sim/frv/ChangeLog-2021 | 3368 ++++++++++++++++++++++++++++++++++++++++++++++++ 2 files changed, 3368 insertions(+), 3368 deletions(-) delete mode 100644 sim/frv/ChangeLog create mode 100644 sim/frv/ChangeLog-2021 (limited to 'sim/frv') diff --git a/sim/frv/ChangeLog b/sim/frv/ChangeLog deleted file mode 100644 index 5a5cd4b..0000000 --- a/sim/frv/ChangeLog +++ /dev/null @@ -1,3368 +0,0 @@ -2021-06-30 Mike Frysinger -
