-Subject: [PATCH 16/16] Revert one of the force_subreg changes
-
-One of the changes in g:d4047da6a070175aae7121c739d1cad6b08ff4b2
-caused a regression in ft32-elf; see:
-
- https://gcc.gnu.org/pipermail/gcc-patches/2024-June/655418.html
-
-for details. This change was different from the others in that the
-original call was to simplify_subreg rather than simplify_lowpart_subreg.
-The old code would therefore go on to do the force_reg for more cases
-than the new code would.
-
-gcc/
- * expmed.cc (store_bit_field_using_insv): Revert earlier change
- to use force_subreg instead of simplify_gen_subreg.
-
-(cherry picked from commit b694bf417cdd7d0a4d78e9927bab6bc202b7df6c)
