[Gcl-devel] native relocation on Mac OS X

[Aurelien Chanudet]

Hi all,

As a first step towards using BFD to perform native relocation on Mac 
OS X, I've written some code to load, link and natively relocate object 
files on Mac OS X. As a result, fasloading can now be achieved without 
using the external ld linker.

This took me longer than expected, because I had to manually address 
relocation overflows that might occur when the branch displacement does 
not fit in 24 bits. I know gcc 3.3 has a "-mlongcall" flag but I'm 
still using gcc 3.1 for some other reason. (Apple's gcc has its own 
"-mlongbranch" flag, but this didn't help, though.)

The first good news is that Maxima 5.9.0 now successfully compiles 
without the alternate linking mechanism. "make check" chokes on 
"Problem 43". I suspect this corresponds to the 3rd issue listed under 
the "Know issues" section of the "NEWS" file included in the source 
directory.

The second good news is that acl2 also compiles fine. I've run "make 
check" yet for acl2, as this took me over one night the last time I did 
it, but I'm planning to.
