[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=]
