llvm dev - Feb 2009 - [LLVMdev] llvm-gcc (pre-release and svn sources) fails to compile on Solaris10/SPARC

I am totally inexperienced with testing using dejagnu, but here's the
output summary that's dumped on my screen >>
                ===  Summary ==
# of expected passes            1774

I see a lot of "FAIL:" messages, and they are somehow always related
to -march=x86 flag for llc. Following is an example of these kind of
errors>>

I'm not really sure what's going on! It'd be great if soemone can
provide some insight into this for me.

I compiled gcc-4.3 from sources.

dejagnu tests all backends. It seems, that you enabled only some  
(sparc only?)

Yes, I compiled llvm with --enable-targets=host-only

I just now re-compiled for all targets, and following are the results
of make check>>

		===  Summary ==
# of expected passes		3104
# of unexpected failures	110
# of unexpected successes	2
# of expected failures		19
