There is support for the LEON3 processor available in Binutils 2.24 and the GCC 4.8 branch and GCC mainline. GCC 4.8 branch: http://gcc.gnu.org/viewcvs/gcc/branches/?view=log&pathrev=205331 GCC mainline: http://gcc.gnu.org/viewcvs/gcc/trunk/?view=log&pathrev=202664 It is mandatory to use this option for SMP on LEON3 since it enables usage of C11 atomic operations. It makes it also possible to use an inline function for _CPU_SMP_Get_current_processor() which avoids the function call overhead in critical sections.
This is the Real-Time Executive for Multiprocessing Systems (RTEMS). The version number for this software is indicated in the VERSION file.
