Hi All,
This patch adjusts the cost model for Cortex-A53 to increase the costs of
an integer division. The reason for this is that we want to always expand
the division to a multiply when doing a division by constant.
On the Cortex-A53
Hi All,
This patch adjusts the cost model for Cortex-A53 to increase the costs of
an integer division. The reason for this is that we want to always expand
the division to a multiply when doing a division by constant.
On the Cortex-A53 shifts are modeled to cost 1 instruction,
when doing the exp
