[Sbcl-devel] SPARC/Linux port

[Christophe R. <cs...@ca...>]

I just thought I'd give you a status update on the SPARC/Linux SBCL
porting effort. As it currently stands, there are issues with
internal-error, and with arithmetic[*] at the very least; however, by
turning gc off I can get to a top-level prompt (it gets all the way
through cold-init).

I'm therefore hopeful that it won't take too long to fix up these
remaining infelicities; however, I wouldn't advocate holding up 0.7.0
for it -- I'm not that confident about getting the 0.6.13 port up
there, then doing the renamings in the 0.7pre branch...

There is one `invasive' change I've had to make, and I just think I
should run it past you; it concerns the rounding in
src/code/target-hash-table.lisp I've previously mentioned. I propose
the attached patch to get round the bootstrapping issues on the SPARC.

Cheers,

Christophe
