+
+	PR rtl-optimization/99905
+	* combine.c (expand_compound_operation): If pos + len > modewidth,
+	perform the right shift by pos in inner_mode and then convert to mode,
+	instead of trying to simplify a shift of rtx with inner_mode by pos
+	as if it was a shift in mode.

+	defer queueing reg save for hfp and just assert the offset is 0.

+	require both type and TREE_TYPE (@1) to be integral types and either
+	type having smaller or equal precision, or TREE_TYPE (@1) being
+	unsigned type, or type being signed type.  If TREE_TYPE (@1)
+	doesn't have wrapping overflow, perform the subtraction of one in
+	unsigned type.
