[Softpear-cvs] softpear/src/cpu/cpu_generic ppc_cpu.cc,1.13,1.14

[<mas...@us...>]

Update of /cvsroot/softpear/softpear/src/cpu/cpu_generic
In directory sc8-pr-cvs1.sourceforge.net:/tmp/cvs-serv7141/src/cpu/cpu_generic

Modified Files:
	ppc_cpu.cc 
Log Message:
Little changes to the threading concept: CPU can now be started by either calling
"ppc_cpu_run_threaded" or "ppc_cpu_run_unthreaded". In the first case, the memory
allocated by "ppc_cpu_init" is free'ed automatically, in the latter case, it is not
so that the caller has access to the register contents after the CPU has finished.

Added qsort.c example.
