This patch add support for Fujitsu A64FX, as the first step of adding A64FX machine model.
A64FX is used in FUJITSU Supercomputer PRIMEHPC FX1000, PRIMEHPC FX700, and supercomputer Fugaku. The official microarchitecture information of A64FX can be read at https://github.com/fujitsu/A64FX. Changelog: 2020-08-03 Qian jianhua <qia...@cn.fujitsu.com> * config/aarch64/aarch64-cores.def: Add the chip name. * config/aarch64/aarch64-tune.md: Regenerated. * config/aarch64/aarch64.c: Add tuning table for the chip. * doc/invoke.texi: Add the new name to the list.
