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.

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.

This directory contains the GNU Compiler Collection (GCC). The GNU Compiler Collection is free software. See the files whose names start with COPYING for copying permission. The manuals, and some of the runtime libraries, are under different terms; see the individual source files for details. The directory INSTALL contains copies of the installation information as HTML and plain text. The source of this information is gcc/doc/install.texi. The installation information includes details of what is included in the GCC sources and what files GCC installs. See the file gcc/doc/gcc.texi (together with other files that it includes) for usage and porting information. An online readable version of the manual is in the files gcc/doc/gcc.info*. See http://gcc.gnu.org/bugs/ for how to report bugs usefully. Copyright years on GCC source files may be listed using range notation, e.g., 1987-2012, indicating that every year in the range, inclusive, is a copyrightable year that could otherwise be listed individually.
