Exception table setup is processed by common CPU architecture support. For ARM architecture, it can be found in the file rtems/c/src/lib/libbsp/arm/shared/start/start.S and ends by bsp_vector_table_copy_done label. The actual tabel content can be found at bsp_start_vector_table_begin For ARMv7-A and even other variant with hypervisor mode support, it is even not necessary to copy table to address 0 at all because CP15 register can be used to specify alternative table start address arm_cp15_set_vector_base_address(&)bsp_start_vector_table_begin; ARMv7-M have register to set exception table base as well. Updates #2783
