typedef struct Context_Control_fp | Context_Control_fp |
Generally there are 2 types of context to save.
This means we have the following 3 context items:
On the SPARC, we are relatively conservative in that we save most of the CPU state in the context area. The ET (enable trap) bit and the CWP (current window pointer) fields of the PSR are considered system wide resources and are not maintained on a per-thread basis.
#define _CPU_Context_Get_SP | ( | _context | ) | (_context)->o6_sp |
This macro provides a CPU independent way for RTEMS to access the stack pointer in a context structure. The actual name and offset is CPU architecture dependent.
