I'm looking at two functions - __dcache_flush and __icache_flush
found in bsp/sparc/cache-sparcl.S. What puzzles me is that they
are both missing 'retl' instruction. Is it by design, or what?
Could somebody clarify this mystery for me please?
Thanks.

In case anyone is wondering, this file is part of our customer source
release that includes the sources for the Cygmon ROM monitor. I've sent the
necessary fix direct to Gene.

To avoid confusion, the file bsp/sparc/cache-sparcl.S is not part of
eCos, it is part of cygmon. You are correct in that the retl
instructions are missing. An updated version of the file is being sent
separately.
