[cmucl-cvs] CMUCL commit: cross-sol-x86-branch src (compiler/x86/parms.lisp lisp/x86-validate.h)

[Raymond Toy]

    Date: Wednesday, December 15, 2010 @ 07:43:46
  Author: rtoy
    Path: /project/cmucl/cvsroot/src
     Tag: cross-sol-x86-branch

Modified: compiler/x86/parms.lisp lisp/x86-validate.h

Move the spaces around a bit.

compiler/x86/parms.lisp:
o Move the linkage space to #x30000000, which is in the gap between
  the static space and the control stack.

lisp/x86-validate.h:
o Document the memory map for Solaris.
o Set the altstack to the end of the control stack.
.
