If by compatible you mean "can be used with":

I don't see anything that would prevent you from using llvm-d 
together
with deimos bindings for other libraries.

If by compatible you mean "can be integrated into":

Afaik Deimos projects are linked with the libraries, instead of 
loading
them at runtime. This is something I do not want because of the 
coff/omf
hassle with optlink (on win32), which I can avoid by sidestepping 
the linker.

The next problem would be that afaik deimos is for pure C 
bindings only, but as mentioned under "Planned Features" on the 
github page I do plan on more or less recreating LLVM's OOP 
structure (as much as the C API exposes, anyway) in D around the 
C API as close to the original as sensible and feasible. Keeping 
two seperate projects for that seemed inefficient to me, even 
more so when one of them would only change for bug fixes (if any) 
and for new LLVM versions.

Another pro for using runtime loading is that I can move the 
names of the libraries into llvm-d (which is what I did), so 
someone using llvm-d does not have to worry about library names, 
prefixes and suffixes. The most they have to do it to give -ldl 
to the linker on posix.

These are the main reasons as to why I decided against making 
another deimos project in the first place and I can't think of a 
compelling reason for deviating from that decision right now, 
sorry. Correct me if I'm wrong, though, there's much about D I 
don't know yet.

If, however, there are enough people that *really* want a deimos 
version I could fork the project, strip out the shared lib stuff 
and change a few calls in the code generation to create extern 
functions instead of extern function pointers (The process is 
automated via CTFE, a mixin version of the "map" function and 
associative array enums) and that would be it, although I don't 
really see any real benefit to that (other than it being in 
deimos, which I don't think is a key factor now that we have dub 
with its package registry around).
