[Sbcl-devel] x86-64 (aka AMD64, EMT-64) support

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

Hi,

Those who follow CVS will already know that full 64-bit support for
the x86-64 architecture has been merged to CVS HEAD.  Thanks to some
frantic last-minute debugging and firefighting, I hope that
sbcl-0.8.18.15 shows no regressions for people on other platforms
(sbcl-0.8.18.14 was a disaster for little-endian 32-bit users,
unfortunately).

There is still plenty of stuff which could do with work on the x86-64
platform; as well as various failing test files (at last count:
alien.impure.lisp, exhaust.impure.lisp, float.pure.lisp,
foreign.test.sh), the disassembler is somewhat selective in its
understanding of the instruction set; I'm sure there are other
problems lurking, maybe in less-exercised areas of the code such as
ROOM (or its close sibling MAP-OVER-ALLOCATED-OBJECTS).

Please test and enjoy: and many thanks to all who have participated in
this effort.

Cheers,

Christophe
