-Subject: [PATCH 14/16] Add force_lowpart_subreg
-
-optabs had a local function called lowpart_subreg_maybe_copy
-that is very similar to the lowpart version of force_subreg.
-This patch adds a force_lowpart_subreg wrapper around
-force_subreg and uses it in optabs.cc.
-
-The only difference between the old and new functions is that
-the old one asserted success while the new one doesn't.
-It's common not to assert elsewhere when taking subregs;
-normally a null result is enough.
-
-Later patches will make more use of the new function.
-
-gcc/
-	* explow.h (force_lowpart_subreg): Declare.
-	* explow.cc (force_lowpart_subreg): New function.
-	* optabs.cc (lowpart_subreg_maybe_copy): Delete.
-	(expand_absneg_bit): Use force_lowpart_subreg instead of
-	lowpart_subreg_maybe_copy.
-	(expand_copysign_bit): Likewise.
-
-(cherry picked from commit 5f40d1c0cc6ce91ef28d326b8707b3f05e6f239c)
