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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/branches/release_16@24155 91177308-0d34-0410-b5e6-96231b3b80d8

// fpcmp is a tool that basically works like the 'cmp' tool, except that it can

// tolerate errors due to floating point noise, with the -r and -a options.
