Re: current 3.0 on status on embedded targets

[Toshi Morita <tm2 at best dot com>]

My addition:

v850-*:
	AFAIK it's broken in both the 3.0 branch and CVS mainline
        because nobody has reviewed/approved the GCC patch to fix
        the marking of freeable nodes in the v850 backend.

Does RTEMS use newlib? Because the sh-* configurations including
sh-elf now have a dependency on newlib.
