Hi,
While looking at something else I realized that we had MEMORY_MOVE_COST
defined in the backend. However we also have the more recent target hook
defined for this through TARGET_MEMORY_MOVE_COST making it obvious to
remove this definition, given that the only use of the macro
MEMORY_MOVE_COST is in the default target hook implementation for
TARGET_MEMORY_MOVE_COST :)
Ok for stage4 ? Just rebuilt the compiler (cc1 and cc1plus), built a few
large enough .i files that I had lying around saw no difference in code
generated as expected.
regards,
Ramana
