commit r16-1494-g59fbc99f8ee35fc1a7bcae4bed3e7bfaec38b538 Author: Kito Cheng <[email protected]> Date: Tue Jun 10 11:17:45 2025 +0800 driver: Try to read spec from gcc_exec_prefix if possible GCC will try to read the spec file from the directory where it is installed, but it should try to read from gcc_exec_prefix rather than standard_exec_prefix, because the latter is not the right one if compiler has been relocated into other places other than the path specfied at configuration time. gcc/ChangeLog: * gcc.cc (driver::set_up_specs): Use gcc_exec_prefix to read the spec file rather than standard_exec_prefix.
