Subject: [AArch64] Give some new costs for Cortex-A53 floating-point operations
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=f6dbc402e18a4d8e4f4941c4e7b2f9ec4e3c9ed4;p=gcc.git

[AArch64] Give some new costs for Cortex-A53 floating-point operations

gcc/

	* config/arm/aarch-cost-tables.h (cortexa53_extra_costs): Make FP
	costs relative to the cost of a register move.
