Segher Boessenkool 6e21f3b52e rs6000: Separate shrink-wrapping for FPRs
This patch implements separate shrink-wrapping for the non-volatile
floating point registers (FPR14..FPR31).  It is pretty much exactly
analogous to the code for GPRs.


	* config/rs6000/rs6000.c (struct machine_function): Add field
	fpr_is_wrapped_separately.
	(rs6000_get_separate_components): Use 64 components.  Handle the
	new FPR components.
	(rs6000_components_for_bb): Handle the FPR components.
	(rs6000_emit_prologue_components): Handle the FPR components.
	(rs6000_emit_epilogue_components): Handle the FPR components.
	(rs6000_set_handled_components): Handle the FPR components.
	(rs6000_emit_prologue): Don't output prologue code for those FPRs
	that are already separately shrink-wrapped.
	(rs6000_emit_epilogue): Don't output epilogue code for those FPRs
	that are already separately shrink-wrapped.

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.
