This patch try to fix a bug[116347]. I change the name of the
micro-arch,
because I think micro-arch and core have the same name that caused
the error.
gcc/ChangeLog:
* config/riscv/riscv-cores.def (RISCV_TUNE): Rename.
(RISCV_CORE): Ditto.
Conceptually tuning means things like costs and scheduler model while
core defines what instructions can be used. So why are core entries
showing up under known arguments for the -mtune option?
Jeff
In the current definition, different cores need to be configured with
corresponding tuning in `riscv-cores.def`, so we can reuse the core name
in '-mtune' option.
