Since the FP area pointer is passed by reference in _CPU_Context_Initialize_fp() the optional FP area adjustment via _CPU_Context_Fp_start() is superfluous. It is also wrong with respect to memory management, e.g. pointer passed to _Workspace_Free() may be not the one returned by _Workspace_Allocate(). Close #1400.
A lot of explanation needed, will do when known. The score/cpu/sparc64 contains only code that can execute without accessing privileged registers or using privileged instructions. This was done because the privileged registers differ between the sun4u and sun4v models. The model specific and privileged code that would normally be found in score/cpu/sparc64 resides in libcpu/sparc64/@RTEMS_CPU_MODEL@/score or in libcpu/sparc64/shared/score directory. This is primarily the interrupt handling code.
