NewCC - an alternate cc front-end for the microware compiler
==============================================================
NewCC is originally intended for a different compiler but during the
development phase, I saw that it was a minor step to adapt the
cc to the microware compiler-system.
I needed especially the benefits of the pipe-option, because the pair
c68<->o68 used up my whole ram-disk I am using as a fast temp-dir.
At this moment Newcc implements nearly all standard options besides
two I never used (therefore no need for that :-):
-K=n[W|L|CW|CL|F]
and
-W=<dir>
Both can be easily implemented using the arg-parsing scheme, and this
is left to the interested reader :-).
Tests have shown, that compiling with the -p[ipe] option is about
15-20% percent slower than compiling with a sufficient ramdisk as
temp-dir and 20-25% quicker than compiling without a fast ram-disk.
(These values are system-dependant, I do have a quick Harddisk)
For good performance, you have to change the default pipe-buffer-size
to a reasonable value (I use 1K buffers). The bigger the pipe-buffer
the better the performance ...
To install the new cc just compile it with the following line
'cc -ix -f=ccn cc.c'
