[Sbcl-devel] self-compilation improvement

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

Hi,

As part of my penance for slowing down the compiler, find attached a
patch that (I think) speeds up the "./make.sh 'lisp -batch'" process by
a factor of approximately two.

On my laptop, using this patch reduced build time to 35 minutes (from
something closer to 70; I'm measuring that now...) I hope it's obvious
why, and I hope that I haven't missed something in the process...

Cheers,

Christophe
