[PATCH][AArch64] Wire up Cortex-A57 rtx costs
Thu Jan 30 13:48:00 GMT 2014
This patch wires up the aarch64 backend to use the Cortex-A57 rtx costs table
that is proposed at
It also sets the generic tuning to use the Cortex-A57 costs since they are more
sensible for aarch64 systems than the generic ones that were originally written
with aarch32 code generation in mind.
Tested aarch64-none-elf on a model.
Ok for trunk once the prerequisite goes in?
