From: Soumya AR <soum...@nvidia.com> Hi,
This RFC is a continuation of previous patches sent here: https://gcc.gnu.org/pipermail/gcc-patches/2025-May/682702.html As suggested in the earlier thread, I've now added a python script to generete the printing and parsing routines for the JSON tuning parameters from the schema. With this, if changes are made to tune_params, the user can simply regenerate the routines by running the script (albeit after updating the schema). Additionally, instead of removing 'const' from all predfined tune_params structures, I've reworked the patch to only clear 'const' from the individual tuning fields and instead update the structures using temporaries. Best, Soumya Soumya AR (6): aarch64 + arm: Remove const keyword from tune_params members and nested members aarch64: Enable dumping of AArch64 CPU tuning parameters to JSON json: Add get_map() method to JSON object class aarch64: Enable parsing of user-provided AArch64 CPU tuning parameters aarch64: Regression tests for parsing of user-provided AArch64 CPU tuning parameters aarch64: Script to auto generate JSON tuning routines gcc/config.gcc | 2 +- .../aarch64-generate-json-tuning-routines.py | 370 ++++++++++++ gcc/config/aarch64/aarch64-json-schema.h | 261 ++++++++
