[M3devel] [M3commit] CVS Update: cm3

[Daniel Alejandro Benavides D.]

Hi all:
this is very bad news, sounds like we had a old RT.
I wonder how parallelized was DEC-SRC Vulcan or alike environments.
Thanks in advance

If we are talking about turning on optimizations in the m3makefile, then the
answer is:

Yes!  At least with CM3 it makes a huge difference in runtime.  Without
the optimizer CM3-produced code runs far slower than PM3-produced code
(I've seen 3X I think.)  With it, CM3 can sometimes keep up.  Unless you
use a lot of TYPECASE or other constructs that have a much less efficient
implementation in the CM3 libraries than in the PM3 libraries.
