registers. The patterns can handle pop multiple with writeback and return (loading into PC directly). To handle return, the patterns use a new special predicate pop_multiple_return, that uses ldm_stm_operation_p function from a previous patch. To output assembly, the patterns use a new function arm_output_multireg_pop. This patch also adds a new function arm_emit_multi_reg_pop that emits RTL that matches the new pop patterns for integer registers. This is a helper function for epilogue expansion. It is used by a later patch. 2012-06-18 Ian Bolton <ian.bolton@arm.com> Sameera Deshpande <sameera.deshpande@arm.com> Greta Yorsh <greta.yorsh@arm.com> * config/arm/arm.md (load_multiple_with_writeback) New define_insn.

README
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.
