-Subject: [PATCH]        PR rtl-optimization/81803       * lra-constraints.c
- (curr_insn_transform): Also reload the whole   register for a strict subreg
- no wider than a word if this is for    a WORD_REGISTER_OPERATIONS target.

-Upstream-Status: Backport
-
-This patch removes changes to Changelog from the original patch upstream. This is
-because we are backporting a patch to a stable version, making changes to Changelog,
-especially up '* GCC 7.2.0 released.', feels a little weird.
