[PATCH] Extend MVE patterns
Wed Mar 7 15:40:00 GMT 2007
MVE currently can be applied on insns that are of the form of:
x = x + something
This patch extend MVE to support also insns of the form:
x = something + x. This form can appears when PPC built-in function
builtin_madd is expanded to RTL.
Bootstrapped and tested on ppc.
OK for mainline?

* loop-unroll.c (var_to_expand): New field to support also
insns of the form x = something + x.
(analyze_insn_to_expand_var): Use it.
