The header file gcc/config/microblaze/rtems.h has been updated to define the __USE_INIT_FINI__ macro. This macro is necessary for the RTEMS operating system to select the appropriate procedure for executing global constructors when compiling for the MicroBlaze architecture. Without this definition, the correct mechanism for initializing global variables might not be invoked.
