Hello.
Right now, we use legacy hashing function in cl_option_hasher and I also
need the change for the future fix of PR102585.
Patch can bootstrap on x86_64-linux-gnu and survives regression tests.
Ready to be installed?
Thanks,
Martin
gcc/ChangeLog:
* tree.c (cl_option_hasher::hash): Use cl_optimization_hash
and remove legacy hashing code.
