You can install dejagnu, and run 'make check' in the llvm objdir.
All tests except one pass for me on Solaris10/x86 (LLVMHello.so is not
copied to the correct location for some reason, so that test fails),
it would be interesting to see what happens on Sparc.

Wow, where did you get a 4.3.x compiler for Solaris? Latest I've seen
packaged are 3.4.x and 4.0.x.

I tried building on Solaris10/x86, and I had to use something like
--with-as=/usr/sfw/bin/gas --with-gnu-as --with-ld=/usr/ccs/bin/ld
--without-gnu-ld.

However it failed with an undefined reference to 'copysignl'.
