*	Port of RTEMS to the Texas Instruments C3x/C4x DSP families including	Joel Sherrill	2000-07-26	1	-0/+2
\| \| \| \| \| \| \| \| \| \| \|	a BSP (c4xsim) supporting the simulator included with gdb. This port was done by Joel Sherrill and Jennifer Averett of OAR Corporation. Also included with this port is a space/time optimization to eliminate FP context switch management on CPUs without hardware or software FP. An issue with this port was that sizeof(unsigned32) = sizeof(unsigned8) on this CPU. This required addressing alignment checks and assumptions as well as fixing code that assumed sizeof(unsigned32) == 4.

\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	Problem: a posix thread which is created by pthread_attr_init(&tattr); pthread_attr_setinheritsched(&tattr, PTHREAD_EXPLICIT_SCHED); pthread_attr_setschedpolicy(&tattr, SCHED_RR); pthread_create(&th, &tattr, func, arg); has a first timeslice of 2^32 ticks (changing a running thread to SCHED_RR id ok). I use RTEMS-4.0.0. I am not sure if the problem exists in the current CVS head revision. If it's not fixed, the patch at the end should do it.
