AKCL on a DS5000 and volatile declarations
I am trying to use AKCL on a DECStation 5000 PX. I noticed that there was
no machine definition for it, but went ahead and used the definition for
the 3100. The make was successful, but was not without incident. I had
several failures that either required a minor fix or (gasp) appeared to fix
themselves after typing make again (things like core dumps due to
modification of text space during an autoload).
I proceeded to use AKCL to build Mike Gordon's HOL theorem prover. In
compiling the LISP files, three of them failed during C compilation. After
some research, I determined that it was the volatile declaration
(-DVOL=volatile) that was causing problems. I would get a "bad structure
offset" error message on any object that was declared as volatile and then
referenced using any CMPc*r macro.
I don't understand why this is so (based on my limited understanding of the
volatile declaration) and am concerned that just removing the -D switch
from the string that AKCL uses to compile files will break things somewhere
down the line. (For those files that failed, I added (setq compiler::*cc*
"cc -O G ") to the front and proceeded to build HOL.)
Can anyone offer any explaination? Is there a better AKCL port to a DS5000
than the DS3100 port that exists (i.e. in the works)?
Thanks.
