The following type defines an entry in the SPARC's trap table.
NOTE: The instructions chosen are RTEMS dependent although one is obligated to use two of the four instructions to perform a long jump. The other instructions load one register with the trap type (a.k.a. vector) and another with the psr.
uint32_t CPU_Trap_table_entry::jmp_to_low_of_handler_plus_l4 |
This will contain a "jmp %l4 + %lo(_handler)" instruction.
uint32_t CPU_Trap_table_entry::mov_psr_l0 |
This will contain a "mov %psr, %l0" instruction.
uint32_t CPU_Trap_table_entry::mov_vector_l3 |
This will contain a " mov _vector, %l3" instruction.
uint32_t CPU_Trap_table_entry::sethi_of_handler_to_l4 |
This will contain a "sethi %hi(_handler), %l4" instruction.
