Commit r253825 which introduced some sanity checks for sbitmap revealed a bug in the conversion of cmse_nonsecure_entry_clear_before_return () to using bitmap structure. bitmap_and expects that the two bitmaps have the same length, yet the code in cmse_nonsecure_entry_clear_before_return () have different size for to_clear_bitmap and to_clear_arg_regs_bitmap, with the assumption that bitmap_and would behave has if the bits not allocated were in fact zero. This commit makes sure both bitmap are equally sized. 2017-11-17 Thomas Preud'homme <thomas.preudhomme@arm.com> gcc/ * config/arm/arm.c (cmse_nonsecure_entry_clear_before_return): Allocate to_clear_arg_regs_bitmap to the same size as to_clear_bitmap.
