[4.9] Backport of patch fixing PR61672.
2014-08-05 Richard Biener <rguenther@suse.de> PR rtl-optimization/61672 * emit-rtl.h (mem_attrs_eq_p): Declare. * emit-rtl.c (mem_attrs_eq_p): Export. Handle NULL mem-attrs. * cse.c (exp_equiv_p): Use mem_attrs_eq_p. * cfgcleanup.c (merge_memattrs): Likewise. Include emit-rtl.h. Without this patch build of art with 4.9 is broken (at least on x86). Here is the error msg: art/runtime/interpreter/interpreter_goto_table_impl.cc:2437:1: error: the frame size of 3328 bytes is larger than 1728 bytes [-Werror=frame-larger-than=] Change-Id: I1a33cff567ae91bdbd34a4df6e6360594ae75993 Signed-off-by: Alexander Ivchenko <alexander.ivchenko@intel.com>
