Mark these as failing on sparc instead of sparcv9.
The configure script no longer tells us that we're configuring for SparcV9
specifically.
2004-06-17-UnorderedCompares may work on SparcV8, but it's experiental
anyway.
2005-02-20-AggregateSAVEEXPR should fail on any Solaris machine, as Solaris
doesn't provide complex number support.

It is primarily used as a debugging tool to +reduce test cases from larger programs that are triggering a bug. + +In addition to extracting the bytecode of the specified function, +B<llvm-extract> will also remove unreachable global variables, prototypes, and +unused types. + +The B<llvm-extract> command reads its input from standard input if filename is +omitted or if filename is -. The output is always written to standard output, +unless the B<-o> option is specified (see below). + +=head1 OPTIONS + +=over + +=item B<-f> + +Force overwrite. Normally, B<llvm-extract> will refuse to overwrite an +output file that already exists. With this option, B<llvm-extract> +will overwrite the output file and replace it with new bytecode. + +=item B<--func> I<function-name> + +Extract the function named I<function-name> from the LLVM bytecode. + +=item B<--help> + +Print a summary of command line options. + +=item B<-o> I<filename> + +Specify the output filename.
