Re: [MIT-Scheme-devel] MIT Scheme on the AMD x86-64

[Chris Hanson]

I've pushed some OS X changes to git, but I still haven't got a working compile.

The current problem I'm looking at is this:

./makegen/m4.sh  cmpauxmd.m4 > cmpauxmd.s
as -arch x86_64  -o cmpauxmd.o cmpauxmd.s
cmpaux-x86-64.s:309:32-bit absolute addressing is not supported for x86-64
as: fatal error in /usr/bin/../libexec/gcc/darwin/x86_64/as

According to a Google search, this is a deliberate restriction imposed
by Apple.  I think it's easily fixed, but I'll have to spend some time
looking at the assembly-language reference to figure out how.

I note that this is the sole reference to the SDX macro in that file;
all the ABS references are properly formatted.

BTW, I noticed that you preserved most of the random windows/os2 stuff
in the x86-64 files.  I'm not sure about windows, but all of the os2
stuff can be nuked since it doesn't run in 64-bit mode and never will.
