Hi,

While looking at something else I realized that we had MEMORY_MOVE_COSTdefined in the backend. However we also have the more recent target hookdefined for this through TARGET_MEMORY_MOVE_COST making it obvious toremove this definition, given that the only use of the macroMEMORY_MOVE_COST is in the default target hook implementation forTARGET_MEMORY_MOVE_COST :)

Ok for stage4 ? Just rebuilt the compiler (cc1 and cc1plus), built a fewlarge enough .i files that I had lying around saw no difference in codegenerated as expected.


regards,
Ramana
