To allow runtime updates to tuning parameters, the const keyword is removed
from aarch64 tune_params and all its nested structures and structure members.
Since this patch also touches tuning structures in the arm backend, it was
bootstrapped on aarch64-linux-gnu as well as arm-li

This patch adds support for loading custom CPU tuning parameters from a JSON
file for AArch64 targets. The '-muser-provided-CPU=' flag accepts a user
provided JSON file and overrides the internal tuning parameters at GCC runtime.

This patch adds functionality to dump AArch64 CPU tuning parameters to a JSON
file. The new '-fdump-tuning-model=' flag allows users to export the current
tuning model configuration to a JSON file.

This patch adds a get_map () method to the JSON object class to provide access
to the underlying hash map that stores the JSON key-value pairs.
It also reorganizes the private and public sections of the class to expose the
map_t typedef, which is the return type of get_map().

Hi,
This RFC and subsequent patch series introduces support for printing and parsing
of aarch64 tuning parameters in the form of JSON.
It is important to note that this mechanism is specifically intended for power
users to experiment with tuning parameters. This proposal does no
