| # This library is to override performance-critical routines for aarch64 targets. | ||
| # The implementations are imported from official ARM repo. | ||
| # To reduce dispatching cost, indirect function technique is utilized. Therefore, | ||
| # this library should only be enabled with ELF targets. | ||
|
|
||
| # Considerations: | ||
| # - By Jun, 2022, most enterprise OSs (CentOS 7, CentOS Stream 8 and RHEL 8) still | ||
| # use relatively old glibc on ARM64, where ASIMD, MTE, DC ZVA and SVE are not | ||
| # fully utilized. However, it is becoming increasingly common to use ARM64 instances | ||
| # in cloud-native situations. | ||
| # - `optimized-routines` repo is actively maintained by ARM officials. Therefore, | ||
| # the qualities can be ensured while using it also enables us to keep sync with latest | ||
| # acceleration techniques. | ||

| * \brief | ||
| * Symbol is defined as hidden visibility. Therefore, implementations here are only to override routines with TiFlash | ||
| * binary itself. This is because dependencies like `ld.so`, `libgcc_s.so`, etc will need essential routines like | ||
| * `memcpy` to finish the early loading procedure. Therefore, declare such symbols as visible indirect function will | ||
| * create cyclic dependency. It shall be good enough to override symbols within TiFlash, as most heavy computation works | ||
| * are happening in the main binary. | ||
| * \param NAME: exported symbol name | ||
| * \param SVE: preferred implementation when SVE is available | ||
| * \param MTE: preferred implementation when MTE is available | ||
| * \param ASIMD: preferred implementation for generic aarch64 targets (ASIMD is required by default for Armv8 and above) | ||
