PR rtl-optimization/44194 * calls.c (expand_call): In the PARALLEL case, copy the return value into pseudos instead of spilling it onto the stack. * emit-rtl.c (adjust_address_1): Rename ADJUST into ADJUST_ADDRESS and add new ADJUST_OBJECT parameter. If ADJUST_OBJECT is set, drop the underlying object if it cannot be proved that the adjusted memory access is still within its bounds. (adjust_automodify_address_1): Adjust call to adjust_address_1. (widen_memory_access): Likewise. * expmed.c (store_bit_field_1): Call adjust_bitfield_address instead of adjust_address. Do not drop the underlying object of a MEM. (store_fixed_bit_field): Likewise. (extract_bit_field_1): Likewise. Fix oversight in recursion. (extract_fixed_bit_field): Likewise. * expr.h (adjust_address_1): Adjust prototype. (adjust_address): Adjust call to adjust_address_1. (adjust_address_nv): Likewise. (adjust_bitfield_address): New macro. (adjust_bitfield_address_nv): Likewise. * expr.c (expand_assignment): Handle a PARALLEL in more cases. (store_expr): Likewise. (store_field): Likewise. * dse.c: Fix typos in the head comment. From-SVN: r191302
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.
