Hi,
These are the patches for fixing PR109071 for GCC16 stage1:
Adding -fdiagnotics-details into GCC to provide more hints to the
end users on how the warnings come from, in order to help the user
to locate the exact location in source code on the specific warnings
due to compiler optimizations.

indirect calls when a direct call would suffice.
