[Lightning] x86_64 and jit_addxi_l

[Denis Washington]

Hi,

I tried to compile GNU Smalltalk with JIT compilation enabled on Linux 
x86_64 and after some fiddling [1] got it almost to compile. However, 
one problem remains:

 xlat.c:1714:8: warning: implicit declaration of function 'jit_mulr_l_'
xlat.c:1714:8: warning: implicit declaration of function 'jit_addci_l'
 xlat.c:1715:8: warning: implicit declaration of function 'jit_addxi_l'

and as a consequence:

 libgst/.libs/libgst.so: undefined reference to `jit_addxi_l'
 libgst/.libs/libgst.so: undefined reference to `jit_addci_l'
 libgst/.libs/libgst.so: undefined reference to `jit_mulr_l_'

I investigated the situation concerning `jit_addxi_l' and the only 
definition I found was in core-common.h, and then only as an alias for 
jit_addxi_l for the case that int has the same size as long (which is 
not the case on Linux x86_64, naturally). So my feeling is that there 
must be a definition of jit_addxi_l in Lightning's x86_64 port, but grep 
doesn't yield any such definition in lightning/i386/*.h. Was it 
forgotten? Is it not implemented yet? Or is this simply a problem on my 
part?

Regards,
Denis

[1] I needed to ensure that the only the installed Lightning from git 
and not the one shipped with gst was used by renaming the lightning/ 
folder, but that is for a bug report in the GNU Smalltalk issue tracker.
