Not sure if anyone had tried this but I managed to get LLVM and clang to
build on Nexenta Alpha 7. This is an OpenSolaris/GNU OS.
There wasn't much to change for LLVM, except "#undef"ing a lot of x86
register name equivalents and the like (ie. EAX,ESP,CS,FS...).
There were a couple of similar undef's needed for clang, as well. The
clang testsuite ran fine except for mandel.c again?!? Same file that
wouldn't build on Sparc/Linux, but a different error. I will look at it.
I will try to get llvm-gcc to build but there will probably be some
major issues there We'll see.
Thanks,

P.S. Is there an easier way to do this. Like undef'ing everything once
in some higher level #include?? I had to manually change about 50 files
and I couldn't find where OpenSolaris was #defining these things! Or are
they #defined in gcc somewhere on Solaris?
Well, I managed to get llvm-gcc to build on OpenSolaris/GNU as a
cross-compiler. It was somewhat of a pain since the config files were
mixed up for i386-pc-solaris. I had to manually change some things after
configuration again (this manual changing of stuff is happening because
I don't understand the autoconf/automake toolchain well enough, I
guess).
llvm-gcc produces acceptable binaries that can be linked with the gcc ld
or the native ld. There is an old bug with gcc cross-compilers on
solaris so llvm-gcc doesn't find the native ld automatically, and
it's .o files in /usr/ccs. I had to manually link things with gcc or
native ld. I will see if I can patch things to get a full build of this.
