aarch64: Add support for Ampere-1B (-mcpu=ampere1b) CPU
This patch adds initial support for Ampere-1B core.
The Ampere-1B core implements ARMv8.7 with the following (compiler
visible) extensions:
- CSSC (Common Short Sequence Compression instructions),
- MTE (Memory Tagging Extension)
- SM3/SM4
gcc/ChangeLog:
* config/aarch64/aarch64-cores.def (AARCH64_CORE): Add ampere-1b
* config/aarch64/aarch64-cost-tables.h: Add ampere1b_extra_costs
* config/aarch64/aarch64-tune.md: Regenerate
* config/aarch64/aarch64.cc: Include ampere1b tuning model
* doc/invoke.texi: Document -mcpu=ampere1b
* config/aarch64/tuning_models/ampere1b.h: New file.
