So for function splitting when we outlined the function, we should keep around the clobbers that were at the begining of the bb which will be outlined. So change the last stmt to where we split the bb for where the function call will be to be after the clobbers. Note we have to ignore the debug stmts here otherwise you would get a debug comparison failure. This also fixes some of the warnings about dangling-pointers because the clobbers are now correctly handled while function splitting. The testcases test for the cases where the dangling-pointers pointer warnings would show up too. Note only end of storage clobbers in this case. Bootstrapped and tested on x86_64-linux-gnu.

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.
